Abstract

<P>PROBLEM TO BE SOLVED: To provide a presentation support device capable of supporting a presentation not only during practice but also at the time of implementing the presentation, especially reducing the burden on a presenter at the time of implementing the presentation. <P>SOLUTION: The presentation support device detects an utterance speed of the presenter before implementing the presentation, and further detects the utterance speed of the presenter during the presentation implemented (step S202). When the difference between the two pieces of utterance speed information 501 is not within permissible limits, the device creates advice information and output it (steps S203 to S206). For example, if the utterance speed is too fast, the device creates advice information to urge the presenter to speak slowly, if the utterance speed is too slow, the device creates advice information to urge the presenter to speak faster. The advice information is created in response to a changeover of display information 502 outputted on a screen and outputted in voice. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a presentation support apparatus, a presentation support method, and a control program that support a presentation of a presenter.

  2. Description of the Related Art Conventionally, there is a presentation support apparatus that supports presentation of a presenter by presenting information related to presentation contents to an audience by displaying the information on a screen.

Furthermore, presentation support apparatuses that more actively support presenters have been proposed (see Patent Documents 1 and 2). For example, Patent Document 1 supports the creation of a presentation manuscript and displays feedback information as an image on the screen. In addition, the speech at the time of presentation practice is analyzed to calculate acoustic features such as speech speed, speech time, and inflection Then, the presentation practice is supported by evaluating the difference from the ideal value. Further, in Patent Document 2, the presenter's psychological state is recognized and displayed on a prompter, thereby giving feedback information to the presenter and supporting the presentation.

  However, the conventional presentation support apparatus has the following problems.

  (1) There is a problem in the means for giving feedback information. In the support device of Patent Document 1, it is possible to display feedback information as an image. However, since the image is displayed in a place visible to the audience, it cannot be used during the presentation, and the presentation support is performed during practice. It will be limited.

  On the other hand, in Patent Literature 2, feedback information is displayed in a place that is not visible to the audience, such as a prompter, thereby enabling support during the presentation. In this case, however, the presenter must pay attention to both the image on the prompter and the image presented to the audience. In other words, visual information is used for a plurality of uses, which is a heavy burden on the presenter.

  (2) There is a problem of evaluation criteria. In Patent Document 1, the ideal value is often abstract in many cases, and it is difficult to obtain a specific value to be compared. In particular, acoustic features such as speech speed vary throughout the presentation, such as speaking slowly at important points and speaking relatively quickly at points that can be easily completed, and it is difficult to obtain a reference.

  On the other hand, since Patent Document 2 focuses on giving feedback to the presenter, the problem regarding the evaluation value is not great. However, in order to give more positive feedback, it is necessary to evaluate on some basis.

<Configuration of this embodiment>
FIG. 1 is a block diagram showing a hardware configuration during presentation practice of the presentation support apparatus according to the embodiment of the present invention.

  In this presentation support device, a central processing unit 11, an output device 12, an input device 13, a voice input device 14, an external storage device 15, a ROM 16 and a RAM 17 are connected to a bus 20.

  The central processing unit 11 is a device that performs processing such as numerical calculation and control, and executes a control program such as a procedure that is stored in the ROM 16 and that is a feature of the present embodiment. The output device 12 is a device that presents information to the user, and outputs display information 502 read from the external storage device 15.

  The input device 13 includes a touch panel, a keyboard, and the like, and is a device for a user to give an operation instruction to the device or to input information. The voice input device 14 is a device such as a microphone for inputting voice, and for example, inputs voice for presentation.

  The external storage device 15 is a device such as a disk or a nonvolatile memory, and holds speech rate information 501 and display information 502. In addition, the external storage device 15 may be a portable storage device such as a CD-ROM or a memory card, thereby improving convenience.

  The ROM 16 is a read-only storage device, and stores procedures and fixed data shown in the flowcharts of FIGS. The RAM 17 is a writable / readable storage device and holds temporary information such as temporary data and various flags.

  FIG. 2 is a block diagram illustrating a hardware configuration during presentation of the presentation support apparatus according to the present embodiment.

  The configuration of the presentation support apparatus is the same as that shown in FIG. 1 except that an audio output message 601 is recorded in the ROM 16 (or RAM 17), and an audio output apparatus 18 for outputting the audio output message 601 is provided. is there. Since the output of the audio output device 18 should be audible only to the presenter, the audio output device 18 is configured by an earphone, a headphone, or a device capable of outputting with high directivity.

  At the time of presentation, the voice input device 14 may also be used as a voice input device for loud sound. In addition, in the description of the hardware configuration at the time of presentation practice and the hardware configuration at the time of presentation shown in FIG. 1, devices having common functions are denoted by the same reference numerals, but these are not necessarily the same members. There is no need. For example, the hardware for practicing presentation can be configured by a device using a personal computer, and a dedicated device configuration can be used for presentation. In this case, the speech rate information 501 and the display information 502 are shared between the two configurations.

<Process of this embodiment>
Hereinafter, the processing of this embodiment will be described with reference to the flowcharts of FIGS. The following control method can be realized by storing the program according to the flowcharts of FIGS. 3 to 6 in the ROM 16 and executing the program by the central processing unit 11.

I. Basic Flow FIG. 3 is a flowchart showing a basic flow during presentation practice and presentation.

  First, in step S1, a display switching instruction from the input device 13 is received. Next, in step S2, the contents of the display information 502 output to the output device 12 are switched according to the instruction received in step S1.

  The basic flow at the time of practicing presentation and at the time of presentation is the repetition of the display switching instruction input process (step S1) and the display switching process (step S2).

II. Next, a processing flow at the time of practicing presentation will be described with reference to the flowchart of FIG. This flow may be realized as a flow synthesized with the basic flow, or may be operated in parallel as individual flows.

  First, in step S101, the speaking rate of the presenter is calculated. A method for calculating the speech rate will be described later. Next, in step S102, it is determined whether or not the content of the display information 502 output to the output device 12 has been switched. For this display switching determination, the input in the display switching instruction input (step S1) may be used, or the difference between the information output to the output device 12 may be used. As a result of the display switching determination in step S101, if the display is switched, the process proceeds to step S103, and if the display is not switched, the process returns to the first utterance speed calculation process in step S101.

  In the first utterance speed recording process in step S103, the utterance speed information 501 calculated in the first utterance speed calculation process in step S101 is recorded in the external storage device 15. Next, in step S104, information related to the speech rate calculated so far is initialized, and the process returns to the first speech rate calculation process in step S101.

  As a result of the above processing, the speech rate corresponding to the output content of the output device 12 is obtained.

III. Processing Flow at the Time of Presentation Next, a processing flow at the time of presentation will be described with reference to the flowchart of FIG. This flow may be realized as a flow synthesized with the basic flow, or may be operated in parallel as individual flows.

  First, in step S201, the utterance speed (first utterance speed) recorded in the first utterance speed recording process in step S103 is read from the external storage device 15. Next, in step S202, the speaking rate (second speaking rate) of the presenter is calculated. The method for calculating the second utterance speed is the same as the processing in the first utterance speed calculation step S101 (described later).

  Next, in step S203, the difference between the utterance speed read in the first utterance speed reading process in step S201 and the utterance speed calculated in the second utterance speed calculation process in step S202 is calculated.

  In subsequent step S204, it is determined whether or not the speech rate difference calculated in the speech rate difference calculation process in step S203 is within an allowable range. If the speech rate difference is within the allowable range, the process proceeds to step S207, and if it is outside the allowable range, the process proceeds to step S205.

  In the subsequent step S205, advice information to the presenter is generated based on the utterance speed difference calculated in the utterance speed difference calculation processing in the step S203. For example, if the utterance speed calculated in the second utterance speed calculation process in step S202 is too fast, advice information that prompts to speak slowly is generated, and if it is too late, advice information that prompts to speak quickly is generated.

  Next, in step S206, voice output is performed from the voice output device 18 based on the advice information generated in the advice information generation process in step S205, and the process proceeds to step S207.

  In step S207, it is determined whether the output content (display information 502) output from the output device 12 has been switched as in the first display switching determination process in step S102. If the output content has been switched, the process proceeds to the first utterance speed reading process of step S201, and if the display has not been switched, the process proceeds to the second utterance speed calculation process of step S202.

IV. Processing Flow of Speech Rate Calculation Next, a processing flow of speech rate calculation will be described with reference to the flowchart of FIG. This flow is an application of a technique widely used as a voice recognition technique, and it is possible to adopt various techniques devised for voice recognition.

  First, in step S301, a section where the presenter is speaking is detected. In the simplest method, the power of the voice input to the voice input device 14 is calculated, and a section where the power is a certain value or more can be regarded as a voice section.

  In the next step S302, the content of the voice section detected by the voice section detection process in step S301 is recognized. Specifically, speech recognition that allows chaining of all syllables, large vocabulary speech recognition, and the like are performed. In this embodiment, since the purpose is to obtain the speech rate, some misrecognition is allowed.

  In the subsequent step S303, the average syllable time length is calculated from the recognition result obtained in the arbitrary word speech recognition process in step S302 and the time length of the speech section obtained in the speech section detection process in step S301. The reciprocal of this average syllable time length can be used as the speech rate.

  As described above, according to the present embodiment, presentation support can be performed not only at the time of practice but also at the time of presentation by giving advice information by voice using an appropriate voice output device 18 such as an earphone. In particular, when a presentation is performed, the presenter's vision can be concentrated on the image presented to the audience, so the burden on the presenter can be reduced. Since the sound information has a high interrupting effect, it is possible to call attention appropriately even if the presenter concentrates on the information displayed in the image or the act of presentation.

  Moreover, since the reference speech rate is updated each time the display is switched, the speech rate can be changed according to the content of the presentation. Furthermore, using the difference between the utterance speed at the time of practicing the presentation and the utterance speed at the time of the presentation, the presentation as practiced can be performed. For this reason, it is not necessary to give an evaluation standard from the outside.

  The present invention is not limited to the apparatus of the above-described embodiment, and may be applied to a system constituted by a plurality of devices or an apparatus constituted by one device. A storage medium storing software program codes for realizing the functions of the above-described embodiments is supplied to a system or apparatus, and a computer (or CPU or MPU) of the system or apparatus reads and executes the program codes stored in the storage medium. Needless to say, it will be completed by doing.

  In this case, the program code itself read from the storage medium realizes the functions of the above-described embodiments, and the storage medium storing the program code constitutes the present invention. As a storage medium for supplying the program code, for example, a floppy (registered trademark) disk, hard disk, optical disk, magneto-optical disk, CD-ROM, CD-R, magnetic tape, nonvolatile memory card, ROM is used. Can do. In addition, by executing the program code read by the computer, not only the functions of the above-described embodiments are realized, but also the OS running on the computer based on the instruction of the program code performs the actual processing. Needless to say, a case where the function of the above-described embodiment is realized by performing part or all of the processing is also included.

  Furthermore, after the program code read from the storage medium is written to the memory provided in the function expansion board inserted in the computer or the function expansion unit connected to the computer, the program code is expanded based on the instruction of the next program code. It goes without saying that the functions of the above-described embodiments may be realized by performing some or all of the actual processing by the CPU or the like provided on the expansion board or the expansion unit.
