Abstract

PROBLEM TO BE SOLVED: To enable speech data to be surely registered without exerting a burden on a user by announcing the number of registration trial times of speech data at the time of registration of the speech data. SOLUTION: When the speech registration is first judged to be possible by comparing a speech registerable number with the registered number, for example, 3 is set in a counter. Namely, the speech input in speech registration has executed three times (S45, S46). When a user picks up a receiver according to the instruction of a screen, a guidance display and guide tones are generated (S47, S48). The user speaks his or her name to be registered toward the receiver in this state. When the speeches are sensed, the analysis of the inputted speeches is executed (S49, S50). When the speech analysis is normally executed, the value of the counter is decreased by 1 (S51, S52). Announcement is made that the speech analysis is normally executed and the display of the screen to announce the remaining required number of times of the occurrence is executed (S53, S54). When the speech registration of three times is ended, all of the speech data are registered in an unused speech registration region (S55).

[0002]

2. Description of the Related Art Conventionally, telephones and facsimile machines have a function of registering numbers of a plurality of destinations with one-touch keys or abbreviated keys in order to easily dial a destination. Furthermore, register the abbreviation and number of the destination,
A telephone directory function for selecting a desired destination from these while displaying them has been installed and put to practical use. Further, it has been proposed that a voice recognition function is mounted for further improving convenience so that a dial number of a destination is recognized.

[0003]

In principle, in speech data identification by a speech recognition algorithm that presupposes a specific speaker, in order to collate and recognize speech data registered by a predetermined person, the registered person must be registered. Is often not correctly collated unless uttered. Also, when inputting speech for recognition, environmental noise may be mixed in and cause erroneous recognition.
Further, there may be a case where the user is erroneously recognized as uttering due to illness or the like, despite being the registered person.
As a result, the operator may mistakenly recognize the selected destination dial and make a mistaken fax or call. In order to prevent such erroneous recognition as much as possible, it is necessary that voice data to be collated and searched at the time of recognition be correctly registered. If the conditions for registering voice data are poor, the recognition accuracy will be reduced during voice recognition. Therefore, when registering voice data, it is common to perform a plurality of registration trials in order to register the same voice data, and register the data determined to have the best condition in the voice memory.

However, when a user registers the same data by uttering the same data a plurality of times, if the user does not know in advance how many registration attempts should be made, the registration operation is interrupted without performing the necessary number of trials. The user feels excessive stress in operation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides an appropriate guidance at the time of voice registration so that voice data can be reliably registered without burdening a user. With the goal.

Is built-in. The scanner unit 1-1-16 is connected to the apparatus main body by a curl cord, and has a detachable configuration. 1-1-13 is an encoder detection unit, which moves distance data (rotational encoder rotation information) from the output signal of encoder 1-1-16
Is generated and notified to the CPU 1-1-1.

Reference numeral 1-1-14 denotes an image processing unit, and the CPU 1-1-
According to the instruction of 1, the color raw image data is
If the analog RGB signals output from the color contact sensors 1-1-12 (line-sequential
dpi) is input, and converted into 90 dpi digital data of 8 bits for each of RGB (24 bits per pixel), and the obtained converted data is supplied to the DMA controller 1-1-17. In the case of performing color copying directly, an analog RGB signal output from the color contact sensor 1-1-12 (line sequential resolution 200 dpi)
And converts the data into 360 dpi, binary YMCK digital data, and converts the obtained converted data into a DMA controller.
Supply to 1-1-17.

When the color raw image data (90 dpi, RGB) is stored in the DRAM 1-1-18, the DMA controller 1-1-17 transfers the color raw image data to the DRAM 1-1-18 and performs color copying. In the case of direct recording, binary YMCK data of 360 dpi is transferred to the recording control unit 1-1-19.

When the monochrome raw image data is stored in the DRAM 1-1-18, the image processing section 1-1-14 outputs an analog RGB signal (line-sequential 200 dpi) output from the color contact sensor 1-1-12. And enter the monochrome binary 2

When storing the monochrome raw image data in the DRAM, the DMA controller
When the monochrome binary image data is transferred to AM1-1-18 and monochrome copying is performed directly, the recording control unit 1-1-19
And the monochrome binary image data.

Further, the above operation is supplemented by the following. (1) Copying with the scanner mounted on the main body is in the direct mode, and the read data is transferred to the DRAM 1-1-18.
The sheet-shaped document is read and printed on the recording unit without storing one page of data (hereinafter, page storage). Because the page does not need to be stored in the DRAM 1-1-18 and the memory does not overflow even at a high resolution, the resolution is matched to the recording unit 1-1-20, and the read data is 360 dpi in the sub-scanning direction. Also, the copy size is up to B4 width in monochrome, and A
Up to 4 widths.

(2) When the scanner is taken out from the main body and used for copying as a hand scanner, the mode is the memory mode, and the read data is always stored in the DRAM 1-1-18 as a page. This is because the printing speed of the recording unit 1-1-20 is slower than the speed at which a human performs a hand scan without stress, and the speed of the hand scan is increased by temporarily storing pages in the DRAM 1-1-18. It is configured to be able to end execution. In addition, the reading resolution
If it is set to 360 dpi by matching with 1-1-20, the data capacity of one page is too large to occupy the DRAM 1-1-18, which hinders the operation of the device or the DRAM 1-1-18.
The read resolution is limited to 200 dpi for monochrome and 90 dpi for color, for example, because the cost increases if the capacity is increased.

For the same reason, the copy size in monochrome is up to B4 width, but the copy size in color is limited to A6 (or government postcard size) or less. By the way, the data capacity of one page of B4 size is about 700 KB in monochrome 200 dpi and color 90 dpi in color.
And the data capacity of one page of A6 size is about 600KB
And can be stored in the DRAM 1-1-18.

The size and resolution can be further increased by compressing and encoding the data and storing the data in the DRAM 1-1-18. However, as will be described later, since the compression encoding is performed by software, it takes a long time to execute the hand scan. There is a disadvantage that the speed decreases. It is also conceivable to add hardware for high-speed compression encoding, but this will result in a significant increase in cost.

(3) The original transmission with the scanner mounted on the main body is in the direct mode, and the read data is transferred to the modem via the DRAM 1-1-18 without accumulating the pages, and the other side is read while reading the sheet original. Send to facsimile.

(4) When the scanner is taken out from the main body and used as a hand scanner to transmit a document, the mode is the memory mode, and the read data is always stored in the page in the DRAM 1-1-18. This is because the communication speed of the modem 1-1-2 is slower than the speed at which a human performs a hand scan without stress, and the speed of the hand scan is increased by temporarily storing pages in the DRAM 1-1-18. It is configured to be able to end execution. The reading resolution and size have the same specifications for the same reason as the item (2).

Hereinafter, each of the above-mentioned functions (phone book function, voice registration, voice recognition) will be described in more detail.

FIG. 5 is a diagram for explaining an example of the data structure of the telephone directory data and the voice registration memory according to the present embodiment. The upper dotted line in FIG. 5 is the telephone directory data 4-2 managed by the operating task on the SRAM 1-1-24. Phonebook data 4-2
Are generally classified into two types, one is telephone directory data common to all users, and the other is personal telephone directory data.

The common telephone directory data has a telephone directory data table 5-1. The phonebook data table 5-1 includes “abbreviated name” indicating the abbreviated name of the other party, “telephone number” of the corresponding other party, “voice registration” which is a flag indicating whether voice data is registered, When data is registered, a plurality of data blocks each including a “registration number” for specifying the audio data are stored.

The personal telephone directory data is composed of a personal ID table 5-2 and a personal telephone table 5-3. In the personal ID table 5-2, “abbreviated name” indicating the abbreviation of the user who owns the personal telephone directory table, “voice registration” indicating whether or not voice data corresponding to the abbreviation is registered, and voice data are stored. When registered, a data block composed of a “registration number” for specifying the voice data and a “personal phonebook table address” for specifying the corresponding personal phonebook table is stored. Also, the personal telephone directory tables 5-3 exist for the number of users registered in the personal ID table. The data structure of each table is the same as the telephone directory data table 5-1.

The voice registration memory 4-1 is managed by the voice recognition task on the SRAM 1-1-24, and includes a voice registration table.
5-4 and a voice data registration area 5-5 are stored. The voice registration table 5-4 includes “registration number”, “state”, “exclusion flag”, and “registration address”. The “registration number” specifies the audio data registration area 5-5. The “registration number” has a one-to-one correspondence with the “registration number” described in the “phone book data table”, “personal ID table”, and “personal phone book table”. "State"
Indicates whether data is stored in the corresponding audio data registration area 5-5. The “exclusion flag” indicates whether or not the operation task has received a designation not to be compared with the recognition process. The “exclusion flag” is set to “OFF” when any of commands 0, 1, 2, 3, and 4 described below is received in FIG.
The flag is reset to F, and when any of commands 5 and 6 is received, the "exclusion flag" of the registration number designated by the command is set to ON. "Registered address"
Is the actual address of the RAM area where the digitally encoded audio data is stored. Voice data required for performing voice recognition is registered in the voice data registration area 5-5.

In the above data structure, telephone directory data and voice data are linked by a “registration number”. Therefore, for example, for the input voice,
When voice recognition is performed with reference to the data in the voice data registration area 5-5 and a registration number "NO.2" is obtained as a recognition result, the telephone directory data table 5-1 and the personal ID table 5 -2 is searched, and in this case, a telephone number registered with an abbreviation "manab" is obtained from the telephone directory data table 5-1.

The registration number “N” is obtained as a result of the speech recognition.
When "O.7" is obtained, since there is a data block corresponding to the personal ID table 5-2, it is determined that the voice input is a designation of a personal telephone directory. Then, voice recognition for the next input voice is performed in the specified personal telephone directory.
The destination is identified by voice recognition within the range registered in (Personal Phone Book Table 5-3). In FIG. 5, the abbreviation has only three characters, but it is needless to say that the abbreviation is not limited to three characters.

In the present embodiment, a voice recognition environment such as specific speaker recognition can be obtained by using the above-described telephone directory data for each individual, so that the recognition rate of voice recognition can be improved. Further details on the use of the common telephone directory data and the individual telephone directory data will be described later.

FIG. 6 is a diagram for explaining the type and contents of a speech recognition start command issued from the operation task to the speech recognition task. As shown in FIG. 6, there are command types from command 0 to command 6.
Command 0 is used to delete the specified voice registration data from the voice registration memory. The “registration number” in FIG.
Indicates that the command specifies a registration number. The registration number specified here corresponds to the registration number described with reference to FIG.

Commands 1 and 2 correspond to voice recognition task 1-
Used to request the audio registration process from 2-8. Commands 3 and 4 are used to request the voice recognition task 1-2-8 for voice recognition processing. Commands 5 and 6 are also used to request a voice recognition process, and the voice recognition task that receives them deletes the voice registration data of the registration number specified by the command from the comparison target and recognizes it (FIG. 5). "Exclusion flag" in the voice registration table 5-4
N).

FIG. 7 is a diagram for explaining the types and contents of voice recognition result commands issued from the voice recognition task to the operating task. As shown in FIG. 7, command types exist from command 1 to command 4. Command 1
And 2 are used to notify the voice registration result to the operating task 1-2-2. Commands 3 and 4 are used to notify the speech recognition result.

The SRAM 1-1-24 of the present device has:
A switch item "display reason code" is provided, and a state (ON / OFF) desired by the operator can be set in the "function setting" mode. When this is turned on, if the voice registration / recognition processing is unsuccessful, a “reason code” indicating the reason of the unsuccessful operation is reflected in the result command. That is, "Display reason code"
Is ON, in each process of voice registration / recognition, the operating task 1-2-2 respectively issues a command 4 / command 6 (a command including an instruction to attach a reason code when an NG occurs). Speech recognition task using 1-2-8
Instruct Then, the voice recognition task 1-2-8 receiving this command executes the voice recognition result command 2 or 4
Will be used to respond. Here, for example, when silence is detected in a predetermined section (length) of the input voice, it is determined that there is no valid data, and a sound (voice portion) ends in the predetermined section (length). If the voice recognition task 1-2-8 detects that it is not, the voice recognition task 1-2-8 determines that the input time has been exceeded, and includes the reason code corresponding to this error state in the voice recognition result command 2 or 4.

FIG. 8 shows reason codes according to the present embodiment,
FIG. 11 is a diagram illustrating an example of a relationship between a process type and a reason content. FIG.
The operator can know the reason of the NG that has occurred by placing the contents shown in the above in an instruction manual or the like. In the facsimile apparatus of this embodiment, if "display reason code" is ON, a reason code as shown in the figure is displayed on LCD1-3-6 on the operation panel together with a display indicating NG. You. For this reason, it is possible to provide important guidance at the time of manufacturing inspection and at the time of user use. The display at the time of NG occurrence may display not only the reason code but also the content of the reason. To do so, a character code string representing the reason content corresponding to the reason code or the LCD1-
The pattern data itself representing the reason content to be displayed on 3-6 is stored in advance, and the data corresponding to the generated reason code is read out and displayed on the LCD 1-3-6. Further, a coping method may be displayed instead of the reason content.

The detailed operation of registering and operating the telephone directory function in the facsimile apparatus of this embodiment and performing the destination dialing by voice recognition will be described below.

<Phone Book Registration Related> The processing related to phone book registration includes creation of an individual phone book, “new registration”, “registration correction”, and “registration” for a common phone book and an individual phone book. There are "delete contents" and "delete audio data". Various methods are conceivable for executing each process, such as selecting a desired function from a menu.
In the present embodiment, the selection operation of the process is not limited.

(1) Creation of Individual Phone Book FIG. 9 is a view for explaining the display contents in the operation of creating an individual phone book according to the present embodiment. FIG. 10 is a flowchart showing a procedure for registering an individual telephone directory according to the present embodiment.

When the user operates the function menu or the like to select a personal telephone directory creation process, in step S11 FIG.
An initial screen as shown in FIG. In this state, if the set key 1-3-10 is pressed, the process proceeds to step S12.
Then, the process proceeds to S13, where an abbreviation input screen as shown in FIG. 9B is displayed, and the user inputs an abbreviation. As an operation, when a desired character is selected from the lower part, the character is sequentially arranged at the position of the @ cursor in the upper part, and the cursor is moved to "Owari" in the lower part to complete the abbreviation input. When the completion of the abbreviation input is indicated in this manner, the process proceeds to step S1.
The process proceeds from Step 4 to Step S15.

In step S15, the personal ID table
A new data block is added to 5-2, the abbreviation entered in step S13 is registered in the "abbreviation" field, and the address of the newly assigned personal telephone directory table is assigned to the personal ID table 5-2. In the "Personal phonebook table address" column. Then, in step S16, as shown in FIG. 9C, a display indicating completion of registration of the personal telephone directory is performed.

Subsequently, in step S17, FIG.
(E) is displayed and an inquiry is made as to whether or not to register audio data. Here, if the user selects “Sinai”, the process is terminated as it is.

On the other hand, if the registration of the voice data is set to "NO", the process proceeds from step S18 to step S19, and a voice registration process for generating voice recognition data is performed. The voice registration process will be described later with reference to FIG. The data obtained by this voice registration processing is registered in the voice data registration area 5-5. And step S
At 20, the appropriate data for linking the abbreviation with the audio data is written in each column of the audio registration table 5-4 and the personal ID table 5-2.

(2) Telephone Directory Registration Processing Data registration to the telephone directory will be described. Prior to data registration, it is specified whether the registration destination is a personal telephone directory or a common telephone directory, and if it is a personal telephone directory, which user's telephone directory is specified. The telephone directory is specified, for example, as follows. That is, press the function key 1-3-2,
By operating the up and down cursor keys 1-3-11 and 1-3-12,
If either "Common Phonebook" or "Personal Phonebook" is specified from the menu and a Personal Phonebook is specified,
Abbreviations registered in the personal ID table 5-2 are sequentially displayed on the LCD 1-3-6. By selecting a desired abbreviation, a personal telephone directory to be processed is selected. Therefore, if "data registration" is started in this state, new registration in the selected personal telephone directory is performed. At this point, the registration process in the common telephone directory and the registration process in the personal telephone directory are the same.

FIG. 11 is a diagram showing an example of a screen display in registering data in the telephone directory. FIG. 12 and FIG. 13 are diagrams showing screen display examples in registering voice data in the telephone directory.
FIG. 14 is a flowchart illustrating a process of registering data in a telephone directory. FIG. 15 is a flowchart for explaining a process of registering voice data in a telephone directory.

When a telephone directory is selected and data registration in the telephone directory is selected from a menu, in step S21,
A display as shown in FIG. 11A is performed on the LCD 1-3-6. In this display, “Aki 70 Ken” indicates the number of remaining items that can be registered in the telephone directory. In this embodiment,
Assuming that the number of registrable cases is 100, at the time of the display of FIG. 11A, 30 data items have already been registered.

Next, when the set key 1-3-10 is pressed, the process proceeds from step S32 to S33, and FIG.
Is displayed, and the user inputs an abbreviation (address).

When the input is completed ("Owari" is selected in FIG. 11B), the process proceeds from step S34 to step S35, and the telephone number is input.
The telephone number is entered by dialing. FIG. 11C shows a state in which a telephone number has been input. When the set key 1-3-10 is pressed in this state, the process proceeds from step S36 to step S37,
The entered abbreviation and telephone number are registered in the telephone directory data table 5-1 (or in the case of registration in the personal telephone directory, a designated personal telephone table 5-3).

Thereafter, the flow advances to step S38 to display a screen as shown in FIG. 11E and ask the user whether or not to register voice data. FIG.
If "Sinai" is selected in (e), the process proceeds to step S41, and an inquiry is made as to whether or not to register data in the telephone directory ((f) in FIG. 11). If registration is to be continued, the process returns to step S33; otherwise, the process ends.

On the other hand, when an instruction to perform voice registration is issued in step S38, the process proceeds to step S39.
Then, the voice registration process is performed. Then, step S4
At 0, the data obtained by the voice registration process is registered in the voice data registration area 5-5, as described above in step S20 of FIG. That is, the voice registration table 5-4 and the telephone directory data table 5-1 (if registered in the personal telephone directory, the designated personal telephone directory table
In each column of 5-3), appropriate data for linking the abbreviation and audio data is written.

Next, the voice registration processing will be described.

In step S45 of FIG. 15, the number of voice registrations of the apparatus and the number of voice registrations are compared to determine whether voice registration is possible. In the present embodiment, it is assumed that up to 15 voice data can be registered. If voice registration is not possible, error processing is performed (step S5).
7). Note that this error processing is the same processing as steps S70 to S72 in the flowchart of FIG. 22 described later, and a code indicating the reason that voice registration is determined to be impossible is selected from the reason codes shown in FIG. Presented to the user (here, R04 “Registration number full” in FIG. 8)
Will be selected.

If voice registration is possible, step S46
In FIG. 12, an initial screen as shown in FIG. 12A is displayed, and 3 is set in the counter N. In the present embodiment, the accuracy of the voice recognition processing is improved by performing voice input three times in voice registration, but this counter N counts the number of voice inputs.

When the user picks up the receiver according to the instructions on the screen, the process proceeds from step S47 to step S48,
A guidance display and a guide tone are generated. In the guidance display, first, a display as shown in FIG. 12B is performed, and after a guide tone (peep sound) is generated, a display as shown in FIG. 12C is performed.

In this state, when the user speaks the registered name to the receiver and senses voice, a display as shown in FIG. 12D is made in step S49. And
When the input of the voice is completed, steps S49 to S
Proceeding to 50, the display as shown in FIG. 12 (e) is made and the input voice is analyzed. If it is determined that this analysis has been performed normally, step S51 is performed.
The process proceeds from step S52 to step S52, and if it is determined that there is an abnormality, the process proceeds from step S47 to error processing (step S58). This error processing is similar to steps S70 to S72 in the flowchart of FIG. 22, which will be described later. A code indicating the reason that voice registration is determined to be impossible is selected from the reason codes shown in FIG. And present it to the user.

When the voice analysis is performed normally, the value of the counter N is decreased by 1 in step S52, and in step S53, it is determined whether or not N = 0 as a result. Unless N = 0, it is necessary to perform a voice analysis process (in this embodiment, three times).
In step S54, for example, as shown in FIG. 13A, the fact that the voice analysis has been performed normally is displayed, and a screen for notifying the remaining necessary number of times is displayed. In addition, in (a) of FIG. 13, the display of the remaining number of times (“At 2 Kai”)
May display the value of the counter N.

As described above, when three voice registrations have been completed, the value of the counter N becomes 0, and the process proceeds to step S
From 53, the process proceeds to step S55. In step S55,
All of the plurality of voice data uttered to the unused voice data registration area 5-5 are registered in correspondence with the data input in steps S33 and S35. The voice data to be registered here may not be all voice data, but may be selected only with good conditions, or may be the best data created from a plurality of voice data. During this time, FIG.
A screen for notifying that the voice registration process is being performed as shown in FIG. When the registration of the audio data is completed, post-processing is performed in step S56. That is, a display as shown in FIG.
When the receiver is instructed to return to the original state, and in response to the detection that the receiver has been returned, a screen for notifying the completion of the voice registration process as shown in FIG. 13D is displayed, and the registration is completed. Is shown. Then, as shown in FIG. 13 (e), a screen for the operator to instruct whether or not to continue the voice registration of another item is displayed. When "Sinai" is instructed, a call is also made. (FIG. 10 or FIG. 1)
Returning to 4), if “Sur” is instructed, step S
Return to 33.

(3) Correction of Registered Contents in Phone Book The operation for correcting the contents registered in the phone book will be described. Since the control procedure of this process is clear from the procedure of the operation described below and the presentation of the display screen according to the procedure, here, only the operation procedure will be described with reference to FIG. FIG. 16 is a diagram illustrating an operation of correcting the registered contents of the telephone directory data according to the present embodiment.

For example, in the standby state of the apparatus, the "phone directory" key (setup key 1-3-10) is pressed, and the abbreviation (destination) to be registered / corrected is selected by the up / down cursor keys. An example of the screen display at this point is as shown in FIG. The display of “V” at the right end of the display indicates that the data for voice recognition is registered in the registered data. Next, when the "kana / alphanumeric" key is pressed, a correction screen as shown in FIG. 16B is displayed. Note that the lower candidate character is selected with the up, down, left, and right cursors, and the upper cursor is moved with the “* #” key.

Here, when "K" of "Kimura" is corrected to "TA", the result is as shown in FIG. 16 (c). Then, when "Owari" is selected, the display of FIG. 16D is displayed in order to complete the operation of correcting the abbreviation and to perform the operation of correcting the number. When changing the number, the currently registered number is deleted once by the "delete" key, and then the number is input again by dialing. FIG. 16E shows a state in which the numbers are reset.

After the numbers have been reset, the correction process is terminated by pressing the set key. On the other hand, if there is no change in the number, the set key is pressed from the state shown in FIG.

Next, a screen display as shown in FIG. 16 (f) is made to instruct the user whether or not the voice data should be corrected. If audio data has already been registered for the data, and “Sur” is selected on the screen in FIG. 16F, a screen as shown in FIG. 16G is displayed, and the audio data is replaced. Inquire. In other words, according to this correction operation, voice data registration is started by selecting “NO” on the screen of FIG. 16F for registered data for which voice data has not been registered. For data for which voice data has already been registered, when “Sur” is selected on the screen of FIG. 16F, a screen display as shown in FIG. An inquiry is made as to whether or not the replacement can be performed (that is, whether or not the registered voice data can be erased). FIG. 16 (g)
When "Sinai" is selected on the screen, the registration processing of the audio data is not performed.

(4) Deletion of Registered Contents in Phone Book The operation for deleting the contents registered in the phone book will be described. Since the control procedure of this process is clear from the procedure of the operation described below and the presentation of the contents of the display screen according to the procedure, only the operation procedure will be described with reference to FIG. FIG. 17 is a diagram illustrating an operation of deleting registered contents of telephone directory data according to the present embodiment.

While the apparatus is in the standby state, the user presses the "Phonebook" key (setup key 1-3-10) and selects the abbreviation (destination) to be registered / corrected with the up / down cursor keys. An example of the screen display at this point is as shown in FIG.

In this state, when the erase key 1-3-5 is pressed, the state becomes as shown in FIG. Then, when the setup key 1-3-10 is pressed, the display is displayed as shown in FIG. At this point, the telephone directory data registered with the abbreviated name “Kimura Takuya” is the telephone directory data table 5-1 (or the specified personal telephone directory table 5-3 if registered in the personal telephone directory). Removed from. At this time, if audio data is registered in the erased data, the audio data is also erased together. That is, in the telephone directory data table, the voice registration table 5-4 is searched for the "registration number" of the data block to be deleted, and the "state" of the corresponding data block is made empty.

When the erasing process is completed as described above, the display is displayed as shown in FIG.
7 (d).

(5) Deletion of Audio Data Next, a method of deleting only registered audio data will be described. FIG. 18 is a diagram illustrating a procedure for deleting audio data. When deleting voice data, first, an abbreviation (either a destination abbreviation or an individual phonebook abbreviation) to be deleted is displayed by the telephone directory function. When the "kana / alphabet" key (in this embodiment, the redial key 1-3-26 is substituted) is pressed down and the abbreviation and the telephone number are determined as they are, the display is as shown in FIG. 18 (a). Here, when "Sinai" is selected, (b) in FIG.
Is displayed as shown in (2), and an inquiry is made as to whether or not to delete the audio data. Here, when “Sur” is further selected, the audio data of the registered data is deleted, and a display as shown in FIG. 17C is performed.

[0099] The abbreviation is displayed in the telephone directory and "Kana /
After pressing the "alphabet" key and confirming the name and telephone number as they are, selecting "Sulu" in the display of FIG. 18 (a) displays as shown in (d) of FIG. Can be replaced.

(6) Phonebook Search Operation Next, search of phonebook data will be described. FIG. 19 is a diagram showing an example of a screen display corresponding to an operation at the time of telephone directory search. Press the phonebook key (set key 1-3-10) in the standby state or after capturing the line, and press the up / down cursor movement key 1-3
By operating the buttons 11,1-3-12, the abbreviations registered in the telephone directory are sequentially displayed (for example, in order of alphabetical order) on the LCD 1-3-6 (from (a) to (c) in FIG. 19). )). FIG.
When the down cursor key is pressed from the state shown in FIG.
(B). When the up cursor key is pressed in this state, the state becomes as shown in FIG. 19 (c).

When the displayed abbreviation is selected and the right cursor key is pressed, a detailed display (number display) as shown in FIG. 19D is displayed.

In this state, operating the up / down cursor keys performs the same operation as pressing the up / down cursor keys from the state immediately before the detailed display. Also, stop key 1-3-18
Pressing returns to the standby state, or to the display of "TEL =" if the line is being captured.

When the set key 1-3-10 is depressed in any of the states (a) to (c) of FIG. 19 (in this example, the state of FIG. 19 (c)), If the line is being captured, a display is made as shown in FIG. Unless the line is being captured, the pressing of the set key is ignored, and the display state of FIG. 19C is maintained. (7) Phonebook Search by Voice Recognition Next, a phonebook search by voice recognition will be described. By pressing the voice recognition key 1-3-22, the abbreviation of the destination is uttered, and the voice is recognized, whereby the destination dialing using the common telephone directory is executed. Or voice recognition key 1-
Press 3-22 to utter a personal ID (such as Miyuki or Tetsuya in Fig. 5).
A personal telephone book table is specified from Table 5-2.
When the personal telephone directory table is selected, the destination dial using the personal telephone directory is executed by further uttering the abbreviation of the destination and recognizing it.

FIGS. 20 and 21 are diagrams for explaining the operation procedure of telephone directory search by voice recognition. FIG.
FIG. 4 is a diagram for explaining a processing procedure of a telephone directory search by voice recognition.

When the voice recognition key 1-3-22 is pressed while the apparatus is in a standby state, the operation task 1-2-2 starts a telephone directory search process by voice recognition. First, in step S61, an initial screen shown in FIG. 20A is displayed, and an initialization process of setting the value of the counter N to 0 is performed. In this initialization process, the operating task 1-2-2 sets all "exclusion flags" of the voice registration table 5-4 to OFF.

If it is detected in step S62 that the user has taken off-hook of the handset 1-3-1, the flow advances to step S63 to provide a guidance display as shown in FIG. 20B and a guide tone (beep sound). Is output. Thereafter, as shown in FIG. 20 (c), a screen for notifying the user of the state in which the utterance can be started is displayed, and the user waits for a voice input.

In step S64, when the input of the voice by the user is detected, the operation task 1-2-2 executes the processing shown in FIG.
As shown in (d), a screen for notifying the user that voice data is being stored in the memory, that is, voice data is being taken into the device, is displayed while the input of voice is detected. Issue a speech recognition start command (here, command 3 or 4 in FIG. 6 is issued) to the speech recognition task 1-2-8. Then, step S65
Waits for the input of the voice recognition result command (FIG. 7) from the voice recognition task 1-2-8.

In response to the input of the voice recognition result command, the process proceeds to step S66, and determines whether or not the recognition result has been normally completed based on the input recognition result command. If the result command is a command indicating "NG", the process proceeds to step S70. In step S70, it is determined whether or not the switch item of "display reason code" on the SRAM 1-1-24 is turned on. If the switch item is turned on, an NG reason is displayed on the panel according to the reason code in step S71, and the process waits. Move to state.

On the other hand, if the recognition result is OK, step S
At 67, various tables in the telephone directory data 4-2 are searched based on the registration number included in the recognition result command, and a corresponding item having the registration number is found. If the corresponding item is registered in the personal ID table, the process proceeds from step S68 to step S69, and the abbreviation is displayed on the panel indicating that the personal telephone directory has been designated. Then, the process returns to step S63 to perform the voice recognition process again for the address search of the “personal telephone directory table”. At this time (step S6)
9), the user may instruct that the transfer of the process to the address search using the personal telephone directory table is permitted. Here, if the user refuses to shift to the destination search using the personal telephone directory table, the destination search is performed again on the telephone directory data table 5-1 and the personal ID table 5-2.

When the corresponding item is registered in the common “phone book data table”, or after the personal phone book table is selected, it is registered in the selected “personal phone book table”. If the recognition has been performed, the process proceeds from step S68 to step S73, and in order to show the recognition result to the user, as shown in FIG.
The "address abbreviation" of the item is displayed on CD1-3-6.

Next, in step S74, it is determined whether or not the dial call is facsimile transmission.
The facsimile transmission is determined to be facsimile transmission when a document has been set at the document entrance or when image quality information for facsimile transmission has been set. If it is not facsimile transmission, the process proceeds to step S75, and “wait for set key”
Determines if is specified. SRAM1-1-24
If the item "Wait for set key of voice dial" in the switch is set to "Wait for set key", wait for input of the set key 1-3-10 in step S79.
Press 1-3-10 to shift to dialing. SRAM
1-1-24 switch "Wait for voice dial set key"
If the item is set to “automatic”, step S
From 75, the process proceeds to step S76, and the process shifts to the execution of dialing without waiting for the set key input. When a facsimile transmission operation is performed, it is necessary to press the set key 1-3-10 regardless of the switch (to avoid the possibility of transmission due to erroneous recognition). Therefore, in the case of facsimile transmission, step S75 is skipped and step S75 is performed.
Go to 79.

In the case of automatically shifting to dialing, it takes time for the user to confirm the destination display.
Dial execution is started with a delay of the timer T (steps S76, S78). T is S in advance
This is a predetermined value set in the RAM, but can be changed by a user operation. If the stop key is pressed in this state, the process shifts from step S77 to the standby state, so that the processing can be interrupted.

When the user looks at the abbreviation displayed on the panel while waiting for the set key 1-3-10 to be pressed to execute the dial, and finds that the address is incorrectly recognized, the voice is input here. By pressing the recognition key 1-3-22, the destination selected at that time can be canceled and an instruction to start inputting a new destination can be given (step S79, step S79).
80). If the voice recognition key 1-3-22 has been pressed, the flow advances to step S81 to increase the value of the counter N by one. Then, in step S82, compared with the number of registered audio data, if N is equal to or greater than the number of registered audio data,
Assuming that there is no corresponding recognition result, an error is displayed in step S72.

On the other hand, if N is smaller than the number of registered voice data, the operating task 1-2-2 requests the voice recognition task to perform voice recognition again excluding the displayed destination. That is, in step S83, in order to exclude the destination selected at that time, the registration number of the voice data is added to the voice recognition start command (command 5 or 6) of the limited recognition to perform the voice recognition task 1-2-8. (Step S84). Then, the process returns to step S65. The voice recognition task turns on the “exclusion flag” of the voice registration data to be excluded corresponding to the registration number added to the input command, and executes the voice recognition process again.

As a result of the voice recognition again, if the recognized abbreviation is incorrectly recognized again, the voice recognition key 1-3-22 may be pressed again without pressing the set key 1-3-10. In this way, new speech recognition is performed with the current recognition destination excluded in addition to the previous recognition destination. That is, in the voice registration table 5-4, the corresponding exclusion flag is turned ON, and the corresponding voice data is not used for the next voice recognition.

The operation procedure shown in FIG. 21 shows a case where a telephone call is made by pressing the voice recognition key after off-hook of the handset (performing facsimile transmission). First, by off-hooking the handset, a screen for prompting the operator to input a telephone number as shown in FIG. 21A is displayed. In this state, a normal dial call is possible. Here, when the voice recognition key is pressed, the display shown in FIG. 21B is made.
(B) to (e). The processing contents are the same as those shown in the flowchart of FIG.

In the example shown in FIG. 22, the number of retries coincides with the number of registered voice data, but is not limited to this. For example, the number to be compared in step S82 may be a predetermined number such as three. When the stop key is detected in step S77, the process ends without executing the dialing. At this timing, the voice recognition key may be pressed again to perform the voice recognition again. (That is, the process moves from step S77 to step S81.)

In the above procedure, the exclusion flag is reset at the start of the speech recognition (step S61), but is not limited to this. For example, if an error occurs in step S7
Alternatively, the exclusion flag may be reset when shifting from 2 to the standby state, when shifting from step S77 to the standby state by the stop key, or when dialing is performed.

As described above, according to the above embodiment, when erroneous recognition (due to a difference between the environment in which the voice is registered and the environment in which the voice is input for recognition) occurs during voice recognition, It is not necessary for the operator to stop the apparatus, return to the standby state, and perform the operation again, and it is possible to immediately retry when an erroneous recognition occurs. Then, at the time of this retry, the operability and reliability can be greatly improved because voice data candidates that were erroneously recognized in the previous trials are excluded.

Further, the voice data excluded from the voice recognition is automatically restored in the next new operation, so that the operator does not need to delete or re-register the voice data when retrying the voice recognition. Operability and reliability can be greatly improved.

That is, when erroneous recognition occurs during speech recognition, retry can be easily performed without deleting or reregistering speech data, and the recognition probability at the time of retry is greatly improved. It becomes possible. Here, the retry of the voice recognition is performed again from the voice input. For example, if the voice of another person or the sound of a car is input only when uttered, the candidate group (including the first candidate and the lower candidate) recognized by the voice becomes completely unreliable. . Therefore, it is also efficient and important for reliability to re-input the voice except for the destination that is clearly misrecognized.

Further, according to the above embodiment, in addition to the common telephone directory, individual telephone directory data can be registered, and voice data can be associated therewith. That is, it is possible to realize a voice recognition dial using a voice recognition algorithm for a specific speaker for each personal telephone directory. For this reason, even if it is used by a plurality of users, a recognition dial function with high recognition accuracy can be provided, and convenience and reliability are greatly improved.

Further, according to the above embodiment, when registering voice data for voice recognition, utterance data is registered a plurality of times to improve recognition accuracy. Also, in such a voice registration process, the number of trials required for registering voice data is displayed, so that the operator does not interrupt the process without inputting the required number of voices, The user is freed from remembering how many times the registration is currently performed, and the registration operation can be performed without feeling remarkable stress on the operation.
