Description

The present invention relates to an apparatus and a program for personally practicing an action of making a sound or a sound.
More particularly, the present invention relates to an apparatus and a program for personal practice of telephone reception and the like.

There is a competition called “Telephone Answering (CTI) Competition” organized by Nippon Telegraph and Telephone User Association (http://www.jtua.or.jp/). It is held for the purpose of studying the telephone reception skills of customer service representatives.
In this contest, how to respond to the customer is determined as an issue in advance, but the competitors themselves must think about what kind of response they should make in order to become such a response, and respond in their own words. I must.
As an example, FIG. 29 shows problems in the 2006 competition. The respondent is equivalent to the participating player himself. You must think about this content yourself and speak in a natural way.

In addition, although it is not telephone answering practice, patent document 1 is shown as prior art literature regarding the practice system of English conversation.
JP 2005-31207 A

Now, consider practicing for the telephone reception competition.
If you rely on human resources, you need at least two people in total, a responder and a grader who scores the quality of the practitioner, in addition to the practitioner himself. Since time measurement is also required, three people are required if the grader does not have time measurement.
In other words, those who wanted to participate in the competition needed to gather at least two collaborators.
Naturally, relying on human resources is very time-consuming, so it is difficult to practice just by the convenience of the practitioner.

  The present invention has been made in view of the above points, and an object of the present invention is to provide an audio data reproducing apparatus and an audio data reproducing program that enable only one trainer to practice telephone answering.

  The present invention for solving the above problems includes a plurality of audio data groups, a reference pattern management table for managing reproduced audio data, and a flag indicating whether the reproduced audio data starts from its own side or from the other side. The present invention relates to an audio data device that reads data comprising the above and reproduces audio data and displays a plurality of audio data groups based on the description of the reference pattern management table.

  Unlike a system in which a model has been created in advance as in Patent Document 1 and the like, there is no model in the case of a telephone reception competition. In other words, the practitioner himself must create the model. Therefore, in order to make it easy to create a model and to easily extract only the respondent's part from the model, the voice data of the model is clearly divided between the trainer side and the responder side. Adopted a mechanism.

  According to the present invention, the voice data stored in the apparatus is divided into the other side (response part) and the own side (practice part) and managed by classifying them into two systems of a reference pattern and an input pattern, and the input pattern is brought close to the reference pattern. As described above, it is possible to provide a voice data device, a program, and an utterance practice device capable of efficiently realizing a telephone answering practice alone by performing repeated practice.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

[appearance]
FIG. 1 is a diagram showing a state when a telephone answering practice support program (hereinafter abbreviated as “practice support software”) according to an embodiment of the present invention is activated. In FIG. 1, the reference pattern display area 151, the input pattern display area 152, and the detailed display area 153, which will be described later, are white because of displaying the names of the respective parts. As shown in FIG. 5, it is displayed in an intermediate color. For example, gray ground.
The practice support software 101 is an application program that can be executed on a personal computer running Windows (registered trademark) of Microsoft Corporation. The practice support software 101 requires that the personal computer is equipped with an audio interface due to its nature. As will be described later, PCs record voices when users record voices during telephone reception exercises, play recorded voice data files, and check their progress. This is because a reproduction function is required.

The practice support software 101 reads the task file and expands and displays the contents on the display screen 102.
Then, by pressing the “reference playback” button 103 and the “input playback” button 104 with respect to the displayed contents, the audio is played back.
The task file includes a plurality of audio data files, table data indicating the reproduction order, and the like. Details of the task file will be described later.

There are three main areas in the display screen 102.
One is a reference pattern display area 151.
The reference pattern display area 151 is an area where voice data of a model for telephone reception is displayed.
The other is an input pattern display area 152.
The input pattern display area 152 is an area in which audio data when a telephone answering practice is performed is displayed.
Finally, there is a detailed display area 153.
The detail display area 153 is an area for displaying the audio data relating to the current reproduction position in the reference pattern display area 151 and the input pattern display area 152 while enlarging the time axis and displaying a similarity score which will be described later. . In addition, when a text display mode to be described later is valid, a sentence (text) indicating the content of the conversation is displayed.

The “create new task” button 105 is a button for creating a new task file.
The “task read” button 106 is a button for reading an existing task file.
The “task export” button 107 is a button for creating a task file from the created audio data or the like.
The task file name display field 108 is an area where the name of the read task file is displayed.

The “record” button 109 is a button for recording a reference pattern, which is an example of telephone reception.
When the reference pattern is recorded, the content is displayed in the reference pattern display area 151.
The “continuous” check box 110 is a check box for selecting whether to continuously record the reference pattern.
The “reference reproduction” button 103 is a button for reproducing the recorded reference pattern.

FIG. 2 shows a state in which some empty parts are created.
When the “part addition” button 111 in FIG. 1 is pressed, squares are displayed one after another in the reference pattern display area 151 and the input pattern display area 152. This square is the part.
The part displayed in light color is the practice part 202. The practice part 202 is displayed on, for example, a white background on the actual display screen. This is an utterance portion of the operator who answers the telephone, that is, the user of the practice support software 101.
The part displayed in dark color is the response part 203. The response part 203 is displayed in, for example, an ultramarine background on the actual display screen. This is the utterance part of the other party answering the call. In other words, it is a customer behind the phone.

Returning again to FIG.
The “part addition” button 111 is a button for newly adding a part immediately after the part selected by the cursor.
The “part insertion” button 112 is a button for inserting a new part immediately before the part selected by the cursor.
The “part delete” button 113 is a button for deleting the part selected by the cursor.
The “Create MP3” button 114 is a button for generating an MP3 (MPEG Audio Layer-3: one of audio compression methods used in the MPEG-1 video data compression method) file from the created reference pattern. . This is for practicing by taking the file into a portable music player or the like.

The “practice start” button 115 is a button for practicing telephone reception. Corresponding to the display in the input pattern display area 152, playback of the response part and recording of the practice part are executed alternately.
The “input playback” button 104 plays back the recorded practice pattern.
The “response speed” change field 116 is a numerical value change field for changing the playback speed of the response part in the input pattern in practice.

The “evaluation” button 117 is a button for comparing the part in the reference pattern detail display area 154 with the part in the input pattern detail display area 156 in the detail display area 153 and displaying the result.
The “comparison playback” button 118 is a button for simultaneously playing back the part corresponding to the time axis of the part in the reference pattern detail display area 154 and the part in the input pattern detail display area 156. This time axis correspondence is obtained from the result displayed in the time association area 155.
The “automatic evaluation” check box 119 is automatically selected when a part selection operation is performed and the part in the reference pattern detail display area 154 and the part in the input pattern detail display area 156 are rewritten in the detail display area 153. This is a check box for executing the same operation as when the “evaluation” button 117 is pressed.
The “text display” check box 120 is a check box for displaying the text of the current part in the detail display area 153. When this check box is checked (clicking with the mouse to display “Re”), the entire detail display area 153 is switched to the text display screen.

  The “metronome” check box 121 is a check box for generating a metronome sound, which is an additional function of the practice support software 101. If this check box is checked, a click sound of the tempo set in the tempo setting field 125 next to the practice part is recorded during practice. The click sound is not recorded during recording of the reference pattern and practice of the input pattern.

The timer check box 122 is a check box for selecting a function for displaying the remaining minutes and seconds by calculating backward from the playback time of the practice part in the reference pattern during practice.
The telephone conversation can be too early or too late. In other words, it is desirable that the timing of the model conversation can be faithfully reproduced. Therefore, such a timer function is provided so that the user who is practicing remembers the timing of the conversation.
The “time limit” setting field 123 sets a time that serves as a guideline for defining the total elapsed time during practice. That is, the total elapsed time is set. When this time limit is set, the back of the timer display field 124 turns yellow when the total elapsed time exceeds 90% of the set value. When the total elapsed time exceeds the set value, the back of the timer display field 124 changes to red.
The timer display column 124 shows two elapsed times.
The display column on the left side of the slash (“/”) indicates the elapsed time in the part currently being played back or recorded.
The display content on the right side of the slash (“/”) boundary differs depending on the operation mode.
When the reference pattern and the input pattern are reproduced, the accumulated elapsed time from the beginning of each pattern to the position currently being reproduced is displayed.
When only one part is recorded in the reference pattern, the total playback time of all parts except the part is displayed as the elapsed time of the part being recorded.
During continuous mode recording in the reference pattern, the total playback time of the part ahead of the part is displayed as the elapsed time of the part being recorded.
When practicing, the total playback time of the part ahead of the part is displayed as the elapsed time of the part being recorded or played.
The elapsed time of the part currently being played back or recorded is indicated by the task control unit 908 inside the A / D conversion unit 910 during recording and the D / A conversion unit 911 during playback. The exact elapsed time is obtained by looking at the ring buffer and counting the audio data in bytes.

The “end” button 130 is a button for ending the practice support software 101.
The time axis change buttons 126, 127, and 128 change the width of the time axis of the waveform display in the reference pattern display area 151, the input pattern display area 152, and the detailed display area 153, respectively.

Here, an outline of the practice support software 101 will be described.
The practice support software 101 records a model in advance so that the practitioner can practice the telephone answering alone.
Then practice your side of the example.
The model consists of a collection of voice data on the telephone responder side and the telephone responder side. Since the conversations are alternately performed, the utterance on the telephone responder side follows the utterance on the telephone responder side, and thereafter, voice data is arranged on the telephone responder side, the telephone responder side, and so on.
This abstract concept in the model is called a “reference pattern”.
Therefore, a table is prepared in which voice data is alternately arranged on the telephone responder side and the telephone responder side.
This is the reference pattern management table. The reference pattern management table is the center of the concept of reference patterns.

When practicing on the basis of a model, the voice responder side, that is, the other party's voice data is brought from the model, and the telephone answerer side, that is, oneself listens to the model and practices the answering. Record the results of the practice, listen to them later, and self-judge improvement points.
In order to practice on the basis of an example, an “input pattern” is introduced as an abstract concept different from the reference pattern.
Copy the contents of the reference pattern management table and empty the practice part. A table describing this correspondence is prepared in the same manner as the reference pattern management table. This is the input pattern management table.
In practice, the copied response part is reproduced based on the description of the input pattern management table, and recording is performed on the practice part which has become empty.

Hereafter, the outline of the basic usage of the practice support software 101 will be described with reference to FIGS.
First, when the practice support software 101 is activated, if a task file exists in the usage history, it is read and displayed as shown in FIG. If there is no usage history or the task file does not exist, the initial state is displayed as shown in FIG.
When the “insert part” button 112 or the “add part” button 111 is pressed from the state of FIG. 1, practice parts and response parts are added one after another as shown in FIG.
When recording is performed by pressing the “record” button 109 from the state of FIG. 2, the reference pattern is recorded, and the reference pattern display area 151 is in a state as shown in FIG. When the recording of the reference pattern is completed, the same content as the response part in the reference pattern is displayed in the response part in the input pattern display area 152.
In FIG. 3, since the cursor points to the first part (practice part), the audio data of the first part in the reference pattern is displayed in the reference pattern detail display area 154.
When the “practice” button is pressed from the state of FIG. 3 to start the practice, the practice part in the input pattern display area 152 is recorded, and the response part in the input pattern display area 152 is played back. It becomes a state like 4.
In FIG. 4, since the cursor points to the first part (practice part), the audio data of the first part in the reference pattern is displayed in the reference pattern detail display area 154. Further, the audio data of the first part in the input pattern is displayed in the input pattern detail display area 156.
When the “evaluation” button 117 is pressed from the state of FIG. 4, the evaluation is executed and the display state as shown in FIG. 5 is obtained.
In FIG. 5, since the cursor points to the first part (practice part), the audio data of the first part in the reference pattern is compared with the audio data of the first part in the input pattern. .
As a result, in the time association display area 155, the association of the time axes of both audio data is displayed with fine lines.
In addition, the similarity between both audio data is calculated, and the result is displayed in the similarity score display area 157.

FIG. 6 is a partially enlarged view of the reference pattern display area 151 and the input pattern display area 152.
In the reference pattern display area 151 and the input pattern display area 152, parts are displayed on a gray background color.
In the practice part, a dark waveform is displayed on a light background. For example, it is an ultramarine waveform on a cream base.
In contrast to the practice part, the response part displays a light waveform on a dark background. For example, it is a cream-colored waveform on an ultramarine base.
The waveform displayed in each part is a visualization of the contents of the corresponding audio data file. The vertical axis of the display waveform corresponds to the amplitude value at each time, and the horizontal axis corresponds to relative time.
A number is displayed in the lower left of each part, for example, in red as a noticed color. This is the part number.
“No data” displayed in the practice part in the input pattern display area 152 (“no data” display 602) indicates that there is no corresponding audio data file. The “no data” display part is displayed with a certain width, which is the default value of the practice support software.
The first part of the reference pattern display area 151 and the input pattern display area 152 is displayed in a light color (for example, yellow), unlike other parts displayed in gray. This is the cursor display.
The cursor indicates the reference position when starting recording / practice / playback, which will be described later, and the position of the part to be evaluated.
Apart from the cursor, the part currently being recorded or reproduced is displayed in different colors according to the color of interest. For example, it is displayed in red for recording and green for reproduction.
The cursor is changed by left-clicking the part displayed in the reference pattern display area 151 or the input pattern display area 152 with the mouse when recording / practice / playback is not performed. That is, the position of the cursor is changed only by the user's intention.

[Relationship between data structure, display contents, and internal functions]
FIG. 7 shows the internal data structure of the telephone answering practice support apparatus.
FIG. 8 shows a correspondence relationship between internal data of the telephone answering practice support device and display contents of the reference pattern display area 151 and the input pattern display area 152.
FIG. 9 shows a functional block diagram of the telephone answering practice support apparatus.

First, FIG. 7 and FIG. 9 will be described together.
The practice support software 101 is loaded into a personal computer and executed to constitute a telephone answering practice support apparatus 901.
A task file 903 stored in a non-volatile storage 902 made up of a known hard disk device, flash memory, or the like includes an audio data 702, a reference pattern management table 701, and text data 704 among the respective data shown in FIG. Is stored. The task file 903 is a compressed archive file, and a plurality of files are compressed to form one file. An example is LHA (http://en.wikipedia.org/wiki/LHA).
The audio data 702 is a collection of audio data files 904. It is an audio data file corresponding to each part of the reference pattern display area 151 and the input pattern display area 152, and as an example is a wav file. Note that only the audio data file corresponding to the reference pattern management table 701 is stored in the task file 903.

The reference pattern management table 701 lists the file names of the audio data files 904 for each part displayed in the reference pattern display area 151. When the file is stored in the task file 903, the display order flag 705 includes a line where the file name of the first part is described, that is, the file name described in the first line, and a single space. After “0” or “1” is written, it is written in the form of a plain text file.
The display order flag 705 is a flag indicating whether the reference pattern and the input pattern start from the practice part or the response part. “0” indicates that the practice part starts, and “1” indicates that the response part starts.

  When the reference pattern management table 701 is stored in the task file 903, a line with the file name of the first part, that is, the file name described in the first line, followed by one half-width space is displayed. Along with the description of “0” or “1” in the order flag 705, the file names of the audio data files 904 of each part are listed and output in a text file. An example of the contents of this text file is shown below. In the first line, “0” is written with a space after the file name, so that the first part is a practice part.

ref061101153035005.wav 0
ref061101153036006.wav
ref061101153037007.wav
ref061101153038008.wav

The input pattern management table 703 lists the file names of the audio data files 904 for each part displayed in the input pattern display area 152. It is not stored in the task file 903. When the telephone answering practice support apparatus 901 reads the task file 903, the telephone answering practice support apparatus 901 reads the reference pattern management table 701 from the reference pattern management table text file (not shown) into the RAM 905, and then inputs the input pattern from the reference pattern management table 701. A management table 703 is generated. That is, the input pattern management table 703 is newly generated every time the task file 903 is read.
Text data 704 is plain text. This describes the lines of each part.

Of each data shown in FIG. 7, the audio data 702 is stored in the nonvolatile storage 902 as an individual audio data file 904. The other reference pattern management table 701, input pattern management table 703, text data 704, and display order flag 705 are stored in the RAM 905. The RAM 905 stores counter variables related to operation control described later.
A GUI (Graphical User Interface: a user interface that uses a lot of graphics to display information to the user and can perform most basic operations with a pointing device such as a mouse) functions as an operation unit 906 and a display unit. It can be roughly divided into 907. The operation unit 906 and the display unit 907 constitute the display screen 102.
When the operation unit 906 receives a user operation, the control signal is transmitted to the task control unit 908.
The task control unit 908 provides a function that forms the core of the telephone answering practice support device 901. A user operation is received from the operation unit 906, and the following operation is performed as necessary.
One is to read the data in the RAM 905 and operate the audio signal processing unit 912 for recording / practice / playback operations to be described later.
The other is that the size of the audio data file 904 in the non-volatile storage 902 is acquired, and the accurate elapsed time of recording and playback from the timer unit 909, the A / D conversion unit 910, and the D / A conversion unit 911 which will be described later And so on.
Furthermore, display control of the display unit 907 is performed according to various operations.

The audio signal processing unit 912 performs transmission / reception of digital audio signals and signal processing between the A / D conversion unit 910 and the D / A conversion unit 911 and the nonvolatile storage 902. That is, recording and playback, and speech speed conversion processing described later are performed as necessary.
When recording, the digital audio signal obtained from the A / D conversion unit 910 is recorded in the audio data file 904 designated by the task control unit 908 in the nonvolatile storage 902.
For reproduction, a digital audio signal is generated from the audio data file 904 specified by the task control unit 908 in the nonvolatile storage 902 and supplied to the D / A conversion unit 911.

The timer unit 909 provides a fine timer function in milliseconds.
The A / D conversion unit 910 converts the analog audio signal input from the microphone 913 into a digital signal and supplies the digital signal to the audio signal processing unit 912.
The D / A conversion unit 911 converts the digital signal output from the audio signal processing unit 912 into an analog audio signal and outputs the analog audio signal to the speaker 914.
The A / D conversion unit 910 and the D / A conversion unit 911 incorporate a ring buffer therein, and digital audio data is read from and written to the ring buffer. The task control unit 908 obtains the reading start position of the ring buffer, and calculates an accurate reproduction time or recording time together with accurate time information obtained from the timer unit 909.
The display unit 907 receives various instructions from the task control unit 908. mainly,
Display of each part in the reference pattern display area 151 and the input pattern display area 152;
Timer display,
Text display,
Performs display switching for enabling / disabling buttons.

The file name of the audio data file 904 is devised so that it is always a unique file name. Specifically, it is composed of “year / month / day” + “time” + “count value up to 999”.
In order to generate a new file name of the audio data file 904 in the reference pattern, the character string “ref” indicating the audio data file 904 for the reference pattern, the date and time when generating the file name, and practice support A value obtained by incrementing the count value of the file name generation counter inside the software 101 is added.
In order to newly generate the file name of the audio data file 904 in the input pattern, the date and time when generating the file name and the practice support are added to the character string “obj” indicating the audio data file 904 for the input pattern. A value obtained by incrementing the count value of the file name generation counter inside the software 101 is added.
Suppose that it was 15:30:35 on November 1, 2006. Assume that the count value of the file name generation counter in the practice support software 101 is “003”. At this point, when the audio data file 904 for the reference pattern is generated, the file name ref061101153035004.wav is generated.
Similarly, it is now assumed that it was 15:30:35 on November 1, 2006. Assume that the count value of the file name generation counter in the practice support software 101 is “003”. At this time, when the audio data file 904 for the input pattern is generated, the file name obj061101153035004.wav is generated.
That is, unless the counter value is repeated 1000 times per second, it is almost impossible to generate the same audio data file 904 by human operation.

FIG. 8 shows that the audio data file 904 is associated with all the parts in the reference pattern, but only the response part is associated with the input pattern. This state is immediately after reading the task file 903 or immediately after recording a new reference pattern.
The audio data file 904 corresponding to the response part in the reference pattern display area 151 has the same contents as the audio data file 904 corresponding to the response part having the same number in the input pattern display area 152. For this reason, a copy process is performed to generate an audio data file 904 of the response part of the input pattern from the audio data file 904 of the response part of the reference pattern. Specifically, processing corresponding to the following MS-DOS (registered trademark) command is performed.
> copy ref061101153035004.wav obj061101153035004.wav
That is, a file name starting with “ref” is converted into a file name starting with “obj”, and the contents are copied as they are.
The detailed operation of this process will be described later.

[Initial operation]
FIG. 10 is a flowchart showing the flow of processing immediately after starting the practice support software 101. This process is mainly performed by the task control unit 908.
When the practice support software 101 is activated (S1001), the task control unit 908 checks whether the history of the task file 903 exists from the history information of the data file stored in the Windows (registered trademark) registry or the like. (S1002).
If the history of the task file 903 is in the history information, it is confirmed whether or not the file name actually exists (S1003).
If the task file 903 does not exist or does not exist, default setting is performed (S1004).
If the task file 903 in the history exists, the task control unit 908 reads the task file 903, expands the audio data file 904 to a predetermined directory in the non-volatile storage 902, and stores other data. Read into the RAM 905. At this time, a reference management table text file (not shown) included in the task file 903 is taken into the RAM 905 and converted into a reference pattern management table 701. With this operation, the total number of parts is obtained from the number of records in the reference pattern management table 701, and this is set as a variable N (S1005). At this point, the reference pattern management table 701 has been generated in step S1004 or S1005.
Next, the task control unit 908 performs processing for generating the input pattern management table 703 from the reference pattern management table 701 (S1006).
When the reference pattern management table 701 and the input pattern management table 703 are prepared, the task control unit 908 controls the display unit 907 to perform a process of displaying a part in each display area for each table (S1008). The process ends (S1009).
The screen display state immediately after step S1009 is shown in FIGS.
When the task file 903 is not read (S1004), the screen display state shown in FIG. That is, since there is no task file 903 to be read, only one blank practice part is provided and displayed.
When the task file 903 is read (S1005), the screen display state shown in FIG.
That is, since there is a task file 903 to be read, a predetermined number of parts are displayed in the reference pattern display area 151, and only the response part is displayed in the input pattern display area 152 in the same manner as the display contents of the reference pattern display area 151. Become.

FIG. 11 is a flowchart showing the detailed operation of default setting. This corresponds to step S1004 in FIG. This process is mainly performed by the task control unit 908.
When the process is started (S1101), the task control unit 908 sets the display order flag 705 in the RAM 905 to “0” as a specified value (S1102).
Next, the task control unit 908 newly generates a unique file name for the first part of the reference pattern management table 701 (S1103). The generated file name is stored in the first part of the reference pattern management table 701 (S1104), and the process is terminated (S1105).

FIG. 12 is a flowchart of processing for generating the input pattern management table 703. This corresponds to step S1006 in FIG. This process is mainly performed by the task control unit 908.
When the process is started (S1201), the task control unit 908 first sets 1 to a variable i constituting the counter (S1202). In the following flowcharts, some variables appear. All of these variables are variables provided by the task control unit 908 in the RAM 905. In particular, the variables constituting the counter are local variables that are valid only in the description of each flowchart.
Subsequent processing is loop processing.
First, it is determined whether or not the part with the number indicated by the counter variable i is a response part (S1203).
For example, when the display order flag 705 is “0” (starting from the practice part), the odd part is the practice part and the even part is the response part.
Conversely, when the display order flag 705 is “1” (starting from the response part), the odd-numbered part is the response part and the even-numbered part is the practice part.
That is, the determination result changes depending on whether the counter variable i is an even number or an odd number, and the display order flag 705 is 0 or 1.
As a result of the determination, if the i-th part is a practice part, the task control unit 908 generates a unique file name for the input pattern management table 703 (S1204).
As a result of the determination, if the i-th part is a response part, the task control unit 908 changes the i-th audio data file 904 of the input pattern management table 703 from the i-th audio data file 904 of the reference pattern management table 701. In order to generate, a copy process is performed (S1205). The process is the same as the copy command shown above.
In either case of step S1204 or S1205, the file name of the audio data file 904 for the input pattern management table 703 is obtained at this point. Therefore, the task control unit 908 next stores the file name of the audio data file 904 in the i-th record of the input pattern management table 703 (S1206).
Then, the counter variable i is incremented by 1 (S1207).
Next, it is checked whether or not the incremented part number i is in the reference pattern management table 701 (S1208). If so, the loop process is repeated (S1203), and if not, the process ends (S1209).

FIG. 13 is a state transition diagram using the display screen 102.
When the first part of the reference pattern display area 151 is right-clicked with the mouse in a state where recording / practice / playback is not performed (stop state screen 1301), a menu window 2503 is displayed. In this window, if “start from practice part” or “start from response part” is specified with the mouse, the display order flag 705 is rewritten according to the specified contents, and the reference pattern display area 151 and the input pattern display are displayed. A redisplay process of the area 152 is performed.
When the recording / practice / playback is not being performed, if any part displayed in the reference pattern display area 151 or the input pattern display area 152 is left-clicked with the mouse, the cursor display moves to the part.

FIG. 14 shows display processing in the reference pattern display area 151.
FIG. 15 shows display processing in the input pattern display area 152.
Since both have substantially the same processing contents, here, the display processing of the reference pattern display area 151 in FIG. 14 will be described. This process is mainly performed by the task control unit 908.
When the process is started (S1401), the task control unit 908 sets the counter variable i to a specified value (S1402). The specified value changes according to the situation at that time. In the case of FIG. In the case of recording / practice / playback processing to be described later, the part number immediately after the completion of recording / practice / playback is substituted.
Next, the task control unit 908 checks whether or not the audio data file 904 described in the i-th part of the reference pattern management table 701 actually exists in the nonvolatile storage 902 (S1403). If there is, the display unit 907 is controlled to read the audio data file 904 and display the waveform (S1404). If not, a blank display, ie, “no data” display is performed (S1405). In steps S1404 and S1405, the variable i and the display order flag 705 are confirmed, and if it is a practice part, a group blue display is displayed on a white background, and if it is a response part, a group blue display is displayed.
Next, the task control unit 908 confirms whether or not the display of the part exceeds the display area as a result of the display processing by the display unit 907 (S1406). If not, the variable i is incremented (S1407), and compared with the maximum number N of parts, it is confirmed whether or not N is exceeded (S1408). If N is not exceeded, the display process is repeated again (S1403). If N has been exceeded or the display area has been exceeded in step S1406, the process is terminated (S1409).

FIG. 16 is a flowchart showing processing when the part insertion button is pressed. This process is mainly performed by the task control unit 908.
When the part insertion button is pressed (S1601), the task control unit 908 shifts the contents after the part indicated by the current cursor in the reference pattern management table 701 backward by one (S1602). In step S1602 of FIG. 16, a variable indicating the current cursor position is set to k. The jth content of the reference pattern management table 701 is expressed as Ref (j). For details on this process,
Create a new Ref (N + 1)
Substituting Ref (N) for Ref (N + 1),
Substituting Ref (N−1) for Ref (N),
Substituting Ref (N-2) for Ref (N-1), and ...
The processing flow is to substitute Ref (k) for Ref (k + 1).
Next, the contents after the part indicated by the cursor in the input pattern management table 703 are shifted backward by one (S1603). In step S1603 in FIG. 16, a variable indicating the current cursor position is set to k. The jth content of the input pattern management table 703 is expressed as Obj (j). For details on this process,
Obj (N + 1) is newly created,
Substitute Obj (N) for Obj (N + 1)
Substitute Obj (N-1) for Obj (N),
Substitute Obj (N-2) for Obj (N-1), and ...
The processing flow is to substitute Obj (k) for Obj (k + 1).
That is, steps S1602 and S1603 are processes for freeing a position to be inserted.
After the vacant process, data is actually inserted. The task control unit 908 generates a unique file name for the reference pattern and writes it in the kth of the reference pattern management table 701 (S1604). Similarly, a unique file name for the input pattern is generated and written in the kth of the input pattern management table 703 (S1605).
Then, the variable N holding the number of parts is incremented (S1606).
Finally, input pattern data update processing is performed (S1607), and the process ends (S1608).

FIG. 17 is a flowchart showing the processing when the part delete button is pressed. This process is mainly performed by the task control unit 908.
When the part deletion button is pressed (S1701), the task control unit 908 deletes the audio data file 904 that is the content of the part currently indicated by the cursor in the reference pattern management table 701 (S1702). At this time, if the audio data file 904 to be deleted does not actually exist, the process is skipped. Similarly, the audio data file 904 that is the content of the part currently indicated by the cursor is deleted from the input pattern management table 703 (S1703). At this time, if the audio data file 904 to be deleted does not actually exist, the process is skipped.
Next, the contents after the part indicated by the cursor in the reference pattern management table 701 are shifted forward by one (S1704). In step S1704 in FIG. 17, a variable indicating the current cursor position is set to k. The jth content of the reference pattern management table 701 is expressed as Ref (j). For details on this process,
Substituting Ref (k) for Ref (k + 1),
Substitute Ref (k + 1) for Ref (k + 2), and ...
The processing flow is to substitute Ref (N) for Ref (N-1).
Similarly, the contents after the part indicated by the cursor in the input pattern management table 703 are shifted forward by one (S1705). In step S1705 of FIG. 17, a variable indicating the current cursor position is set to k. The jth content of the input pattern management table 703 is expressed as Obj (j). For details on this process,
Substituting Obj (k) for Obj (k + 1)
Substitute Obj (k + 1) for Obj (k + 2), and ...
The processing flow is to substitute Obj (N) for Obj (N-1).
Then, the variable N holding the number of parts is decremented (S1706).
Finally, input pattern data update processing is performed (S1707), and the process ends (S1708).

FIG. 18 is a flowchart showing input pattern data update processing. This corresponds to step S1607 in FIG. 16 and step S1707 in FIG. This process is mainly performed by the task control unit 908.
When the process is started (S1801), the task control unit 908 substitutes the current cursor position k for the counter variable i (S1802).
Next, the task control unit 908 compares the counter value i with the number of parts N (S1803), and if i is equal to or less than the number of parts N, it confirms whether the i-th part is a response part or a practice part. (S1804).
If it is a response part, the contents of the audio data file 904 referred to by the i-th reference pattern management table 701 are overwritten and copied to the audio data file 904 referred to by the i-th input pattern management table 703 (S1805). ). By this processing, the file name of the audio data file 904 referred to by the i-th in the input pattern management table 703 remains the same, and the content is the same as the audio data file 904 referred to by the i-th in the reference pattern management table 701. Become.
If it is a practice part, the audio data file 904 referred to by the i-th in the input pattern management table 703 is deleted (S1806). If the audio data file 904 does not exist, the process is skipped.
In either case of steps S1805 and S1806, after completing the processing, the counter i is incremented (S1807) and compared with the number N of parts again in step S1803.
If the counter i exceeds the number N of parts in step S1803, the process ends (S1808).

  As described above, it can be seen from FIG. 16, FIG. 17 and FIG. 18 that the number of parts in the reference pattern management table and the input pattern management table is always the same.

[recording]
FIG. 19 and FIG. 20 are flowcharts showing processing when recording a reference pattern. This process is mainly performed by the task control unit 908.
When the “record” button 109 in FIG. 1 is pressed (S1901), the task control unit 908 first substitutes the designated number k indicating the cursor position into the counter variable j (S1902).
Subsequent processing is loop processing.
First, j is compared with the number N of parts (S1903). If j is less than or equal to N, it is checked whether or not the “text display” check box 120 is checked (whether or not the text display mode is set) (S1904). If it is in the text display mode, the text of the j-th part of the text data 704 is displayed (S1905).
Next, the j-th part in the reference pattern display area 151 is displayed in red (S1906), and recording is started (S1907).
During recording, the task control unit 908 continues to check whether an escape key (ESC key) on the keyboard has been pressed (S1908) and whether a right mouse click has been performed (S1909) through the operation unit 906 (S1909). N from S1909 to S1908).
When the ESC key is pressed (Y in S1908), the recording is terminated and the red display of the part is stopped (S1910), and the jth and subsequent parts are displayed again (S1911). That is, the part display process shown in FIG. 14 is performed by substituting j for i. Then, the process ends (S1912).
When the right mouse click is performed (Y in S1909), the recording of the j-th part is terminated and the red display of the part is stopped (S2013). Then, the j-th and subsequent parts are redisplayed (S2014). That is, the part display process shown in FIG. 14 is performed by substituting j for i.
Next, it is confirmed whether or not the “continuous” check box 110 is checked (whether or not it is the continuous recording mode) (S2015). If it is not the continuous mode, the process ends here (S2016). If it is the continuous mode, the next part is recorded, so j is incremented (S2017), and the process is repeated (S1903). If the counter j exceeds the number N of parts, the process ends (S1918).

[practice]
FIG. 21 is a state transition diagram using the display screen 102.
When the “practice start” button 115 is pressed in the normal display state (stop state screen 2101), an utterance practice start window 2102 is displayed.
When a “start” button in the utterance practice start window 2102 is pressed, recording (practice) to the practice part and reproduction of the response part are repeated according to the display contents of the input pattern display area 152 (practice state screen 2103).

22 and 23 are flowcharts showing the processing when practicing the input pattern. This process is mainly performed by the task control unit 908.
When the “practice start” button 115 in FIG. 1 is pressed (S2201), the task control unit 908 first substitutes the designated number k indicating the cursor position into the counter variable j (S2202).
Subsequent processing is loop processing.
First, j is compared with the number N of parts (S2203). If j is less than or equal to N, it is checked whether or not the “text display” check box 120 is checked (whether or not it is in the text display mode) (S2204). In the text display mode, the text of the j-th part of the text data 704 is displayed (S2205).
Next, it is confirmed whether or not the j-th part is a response part (S2206).
If it is a response part, the jth part is displayed in green (S2207), and playback of the jth part is started (S2208).
During playback, it loops (from N in S2310 to S2209) while checking whether the escape key (ESC key) on the keyboard has been pressed (S2209) and whether playback of the part has been completed (S2310). .
When the ESC key is pressed (Y in S2209), the reproduction of the part is interrupted and the green display of the part is stopped (S2211), and the process is ended (S2212).
When the reproduction of the part is completed (Y in S2310), the counter j is incremented (S2313), and the loop process is continued (S2203).
The practice part is located next to the response part (N in S2206). If it is a practice part, the j-th part is displayed in red (S2314), and recording is started (S2315). Here, “recording” is recording with respect to the audio data file 904 related to the practice part.
During recording, it loops (from N in S2317 to S2316) while checking whether the escape key (ESC key) on the keyboard has been pressed (S2316) and whether the right mouse click has been performed (S2317). .
When the ESC key is pressed (Y in S2316), the recording is terminated and the red display of the part is stopped (S2318), and the j-th and subsequent parts are displayed again (S2319). That is, the part display process shown in FIG. 14 is performed by substituting j for i. Then, the process ends (S2320).
When the right click of the mouse is performed (Y in S2317), the recording of the j-th part is terminated and the red display of the part is stopped (S2321). Then, the j-th and subsequent parts are redisplayed (S2322). That is, the part display process shown in FIG. 14 is performed by substituting j for i. Then, the counter j is incremented (S2313) and the loop processing is continued (S2203).
If the counter j exceeds the number N of parts, the process ends (S2223).

[Change response speed]
During practice, the playback speed of the response part can be changed by changing the value in the “response speed” change column 116. This function is called so-called speech speed conversion. The numerical speed change information is transmitted from the operation unit 906 to the task control unit 908. The task control unit 908 issues a control command to the audio signal processing unit. The audio signal processing unit 912 changes the reproduction speed without changing the pitch at the time of reproduction by performing a resampling process on the target audio data file 904 (of the response part to be reproduced in the future).

[Regeneration]
FIG. 24 is a flowchart showing the reproduction process of the reference pattern and the input pattern. This process is mainly performed by the task control unit 908.
When the “reference reproduction” button 103 or the “input reproduction” button 104 is pressed (S2401), a designated number k indicating the cursor position is first substituted into the counter variable j (S2402).
Subsequent processing is loop processing.
First, j is compared with the number N of parts (S2403). If j is equal to or less than N, it is next checked whether or not the “text display” check box 120 is checked (whether or not it is in the text display mode) (S2404). If it is the text display mode, the text of the j-th part of the text data 704 is displayed (S2405).
Next, the jth part is displayed in green (S2406), and playback of the jth part is started (S2407).
During playback, a loop is performed while checking whether the escape key (ESC key) on the keyboard has been pressed (S2408) and whether playback of the part has ended (S2409) (from N in S2409 to S2408). .
When the ESC key is pressed (Y in S2408), the reproduction of the part is interrupted and the green display of the part is stopped (S2410), and the process is ended (S2411).
When the reproduction of the part is completed (Y in S2409), the counter j is incremented (S2412), and the loop process is continued (S2413).

[Replace]
As a result of practice, if the sound recorded in a specific part on the input pattern is better than that on the reference pattern, the part is selected (left mouse click) and the cursor position is updated. Then, the “replace” button 131 is pressed (left mouse click). Then, the audio data file 904 indicated by the part on the reference pattern is overwritten and copied by the audio data file 904 indicated by the part on the corresponding input pattern.
When the audio data of the part selected on the reference pattern is ref061101153035005.wav and the audio data file 904 of the part on the corresponding input pattern is obj061101154035000.wav, the following MS-DOS command is executed and the operation is equal.
> copy obj061101154035000.wav ref061101153035005.wav
That is, the file name stored in the record of the part in the reference pattern management table 701 is kept as it is, and the content is the audio data file 904 having the file name stored in the record of the part in the input pattern management table 703. Can be replaced with the contents.

[Cut / Copy / Paste]
In the telephone answering, the conversation content of the responding partner is often a combination of “Yes” and “Yes”. I would like to use the same audio data for the parts corresponding to such conflicts. Therefore, cut (cut: delete the contents of the specified location and transfer it to the internal buffer area) / copy (copy the contents of the specified location to the internal buffer area without deleting it). It is convenient if / paste (paste: copying the content held in the internal buffer area to a specified location) can be realized.
FIGS. 25A and 25B are views showing a state where a cut / copy / paste menu window is displayed.
In FIG. 25A, a menu window 2502 appears by right-clicking the designated part.
In the menu window 2502, “copy”, “cut”, and “paste” are listed in order from the top, and items “file read” and “file write” continue.
In FIG. 25A, since the contents of the audio data file 904 are not held in the internal buffer area, the characters of the “Paste” item are dimmed and cannot be specified by left clicking the mouse. Yes. Characters of other items are darkly displayed and can be specified by left-clicking the mouse.
When “copy” is selected in the state of FIG. 25A, the contents of the audio data file 904 are copied to the internal buffer area, and at the same time, the menu window 2501 disappears.
When “Cut” is selected in the state of FIG. 25A, the contents of the audio data file 904 are copied to the internal buffer area, the audio data file 904 is deleted, and “no data” is displayed. Then, the menu window 2501 disappears.
When “Paste” is selected while the contents of the audio data file 904 are held in the internal buffer area, the contents of the audio data file 904 of the specified part are the contents of the audio data held in the internal buffer area. Overwritten by At this time, when the part to be “pasted” is displayed as “no data”, since the audio data file 904 does not exist, a new audio data file 904 is created with the file name of the part, The contents of the audio data held in the internal buffer area are transferred (pasted) there.
The items “file read” and “file write” are functions used to read and write the audio data file of the specified part independently.

FIG. 25B shows a state where the right mouse click is performed in the first part of the reference pattern display area 151.
25A differs from the menu window 2502 in that the display order designation item shown in FIG. 13 is added to the menu window 2503. This menu window 2502 is displayed only in the first part of the reference pattern display area 151.

[Evaluation]
When the “evaluation” button 117 is pressed, a time axis correspondence display and a similarity display are performed for the practice part designated by the cursor using a known DP matching processing algorithm.
When the practice support software 101 is not recording / practice / playing, when the part at the cursor is the practice part, the audio signal processing unit 912 receives an instruction from the task control unit 908. The audio data file 904 to be compared is read and an evaluation process is performed. The evaluation result is displayed on the time association display area 155 and the similarity score display area 157 by the display unit 907.
When the “automatic evaluation” check box 119 is checked, when the practice support software 101 is playing back and the part at the cursor position is the practice part, the evaluation process is sequentially performed.
A graphical display of the evaluation is shown in FIG.

[MP3 output]
In recent years, MP3 players using a flash memory or a micro hard disk device as a storage medium have been widely distributed in the market. Also in mobile phones, models with MP3 player functions are widely distributed. (Hereafter, these are collectively abbreviated as “MP3 player”.) If the audio content of the reference pattern in the practice support software 101 of the present embodiment is output to such a device in the MP3 format and reproduced by the MP3 player. , Personal practice on the go.

FIG. 26 shows an MP3 creation menu window that appears when the “Create MP3” button 114 is pressed.
The MP3 creation menu window 2601 is provided with radio buttons and the like for designating the output form of MP3.
The MP3 output format radio button 2602 is a radio button for designating an MP3 output format. You can select one of “Create all parts in monaural format”, “Create in stereo format for each practice part / response part” and “Create practice part in mono format with silence”.
The signal sound designation radio button 2603 indicates whether or not a signal sound is to be added as an output option when “Create a practice part in monaural format with silence” is selected with the MP3 output format radio button 2602. This is a radio button that specifies what format to use. Any one of “Do not insert a signal sound”, “Enter a signal sound at regular intervals”, and “Enter a signal sound at regular intervals” can be selected.
A cue sound interval designation field 2604 is a designation field for designating a cue sound interval in seconds when “insert a cue sound at a fixed interval” is selected with a cue sound designation radio button 2603.
A signal number designation field 2605 is a designation field for designating the number of divisions when “insert a predetermined number of signal sounds” is selected with the signal sound designation radio button 2603.
A “Create” button 2606 is a button for executing MP3 creation.

27 and 28 are flowcharts showing the flow of MP3 output processing. This process is mainly performed by the task control unit 908.
When the “Create” button 2606 in FIG. 26 is pressed (S2701), an initial value 1 is first set to the counter variable i (S2702).
Next, MP3 output format radio button determination processing is performed. It is checked whether “Create all parts in monaural format” is selected (S2703) or “Create in stereo format for each practice part / response part” is selected (S2704). If neither of the conditions in steps S2703 and S2704 is satisfied, it means that “create a practice part in monaural form with silence” is selected (N in S2704).

  When “Create all parts in monaural” is selected (Y in S2703), the counter i is compared with the number N of parts (S2705). If the number is within N (Y in S2705), the audio signal The processing unit 912 is controlled to output monaurally the i-th part of the reference pattern and convert it to the MP3 format (S2706). Thereafter, the counter i is incremented (S2707), and the process is repeated (S2705). If the counter i exceeds the number N of parts (N in S2705), the process is terminated (S2708).

When “Create in stereo format for each practice part / response part” is selected (Y in S2704), the counter i is compared with the number N of parts (S2709). If the number of parts is within N (Y in S2709), it is checked whether the i-th part is a response part (S2710). If it is a response part, the audio signal processing unit 912 is controlled, the part is output on the right channel, and is converted to MP3 (S2711). If it is a practice part, the part is output on the left channel and converted to MP3 (S2712).
Thereafter, the counter i is incremented (S2713), and the process is repeated (S2709). If the counter i exceeds the number N of parts (N in S2709), the process is terminated (S2714).

When “Create practice part in monaural form with silence” is selected (N in S2704), the counter i is compared with the number N of parts (S2815). If the number of parts is within N (Y in S2815), it is checked whether the i-th part is a response part (S2816). If it is a response part, the audio signal processing unit 912 is controlled to output the part in monaural and MP3 conversion (S2817). Thereafter, the counter i is incremented (S2818), and the process is repeated (S2815). If the counter i exceeds the number of parts N (N in S2815), the process is terminated (S2819).
If it is determined in step S2816 that the part is a practice part (N in S2816), the process of determining the cue sound designation radio button 2603 is performed. It is checked whether “Do not insert signal sound” is selected (S2820) or “Input signal sound at regular intervals” is selected (S2821). If neither of the conditions in steps S2820 and S2821 is satisfied, it means that “insert a predetermined divided sound signal” is selected (N in S2821).

  When “Do not insert cue sound” is selected (S2820), the playback time of the audio data file of the i-th part is obtained. Then, the audio signal processing unit 912 is controlled to output silence data corresponding to the time and MP3 conversion (S2822).

  When “insert signal at regular intervals” is selected (S2821), the playback time of the audio data file of the i-th part is obtained. Then, the audio signal processing unit 912 is controlled to output a signal sound at a specified interval for that time, and MP3 conversion is performed (S2823).

  When “insert a fixed-division signal sound” is selected (N in S2821), the playback time of the audio data file of the i-th part is obtained, and the time interval for outputting the signal sound from the specified number of divisions is set. Calculate (S2824). Then, the audio signal processing unit 912 is controlled to output a signal sound at the calculated interval for the reproduction time of the audio data file, and MP3 conversion is performed (S2825).

  After performing MP3 output (S2817, S2822, S2823, S2825), the counter i is incremented (S2818), and the processing is repeated until the counter i exceeds the number of parts (S2815). (S2819).

The following application examples can be considered in the present embodiment.
(1) In the above-described embodiment, audio data is managed as a single audio data file for each part. However, a single audio data file may be used. A relational database that stores voice data can also be used.

(2) In the above-described embodiment, there is only one partner. By developing the technical idea of the present invention, even when there are a plurality of opponents, it is possible to realize the conversation practice software for a plurality of opponents by making some modifications to this embodiment.
Specifically, each part has a flag indicating whether it is a response part or a practice part.
In this application mode, for example, a performer such as a stage or a drama, for example, is extremely suitable when practicing to learn dialogue at home or the like. A task file created by a director reading a script as a reference pattern is given to multiple performers. Performers can run this software on their own personal computer, specify their own part, that is, the practice part, and practice the dialogue.

  (3) If the technical idea of the present invention is applied so that the data to be recorded is not limited to audio data but MIDI data can be recorded and reproduced, it can be applied to musical instrument practice. Instead of text data, it is more convenient to display a score or a tablature score indicating a guitar or bass fingering. In musical instrument practice, the evaluation function clearly displays rhythm shifts, which is also very effective for practice.

  (4) In order to perform repetitive practice, it is possible to add a function to specify the target range of practice and perform repetitive practice.

(5) A response part corresponding to the conflict can be added with a function of randomly reproducing a dedicated audio data file.
In advance, a plurality of audio data files corresponding to each other starting with “res” are prepared.
Then, for the response part of the reference pattern, a function for specifying “conformity” by right-clicking the mouse is added. In the response part for which “consideration” is designated, the audio data file name starting with “ref” is randomly converted into the prepared audio data file name starting with “res”.
This function reduces the labor of creating a reference pattern.

In the present embodiment, a telephone answering practice support program and a telephone answering practice support apparatus realized by executing the program are disclosed.
By classifying and managing the voice data stored in the device into the other party (response part) and one's side (practice part), it is possible to efficiently implement telephone answering practice alone.

The contents of the model (reference pattern) and practice (input pattern) can be clearly seen visually by displaying the waveform of the audio data so that the contents currently stored as data are displayed.
In addition, the display width changes according to the waveform of the audio data, and when there is no audio data, it is displayed with a specified width together with the “no data” notation so that it can be determined at a glance which audio data is present. Can be determined.

By including the display order flag in the data, it is possible to cope with the case where the response part or the practice part is started.
In addition, by having a function of changing the display order flag, it is possible to change when starting from either the response part or the practice part in the middle of data input.

Since the reference pattern can be recorded continuously while pressing the mouse button, the reference pattern can be recorded very efficiently.
When recording or practicing, from the part where audio data recording has been completed by pressing the mouse button, by redisplaying the reference pattern display area for recording and redisplaying the input pattern display area for practice, You can see at a glance how far you have recorded or practiced, and you can visually see the duration of the recorded audio data.

When the recording of the reference pattern is finished, the audio data file having the same contents is copied to the response part of the input pattern and displayed on the input pattern display table. By configuring in this way, data prepared for practice is automatically created, so that the practice can be started immediately after the recording of the reference pattern is completed.
When practicing, the response part is played, and when the playback ends, recording of the practice part starts immediately. By doing so, it is possible to efficiently practice telephone reception alone.

  As a result of the practice, by providing a function for performing a process of replacing the practice part in the input pattern which is good as a result of the practice, it is possible to improve the skill efficiently while performing self practice.

By providing a function that outputs the audio data of the reference pattern as a single audio data, it is possible to practice while listening to a portable music player such as an MP3 player even in an environment where a notebook computer cannot be brought in. .
Furthermore, when voice data is output, it is possible to select whether or not to include a practice part, so that appropriate voice data can be output according to the proficiency level of practice and practice can be performed efficiently.
