Description

  The present invention relates to a voice recognition control apparatus that inputs a voice uttered by a user and executes control corresponding to the recognized voice command when the input voice is recognized as corresponding to a predetermined voice command.

  Depending on the utterance method and individual differences, the utterance may be lost, for example, the beginning or ending of the uttered voice may be weakened or missing, or r consonant may be lost. As described above, when the voice that is spoken is input to the voice recognition control apparatus, if only one voice command corresponding to each control content is registered, the voice recognition control apparatus starts the voice from the input voice. The command cannot be recognized and control cannot be executed.

Therefore, conventionally, a command corresponding to the voice when the voice command is spoken (hereinafter referred to as a “name command”) is managed separately from the voice command, so that the voice is spoken. Even if it exists, the voice recognition control device recognizes the slack command and can execute control corresponding to the slack command (see Patent Document 1).
JP-A-62-111295

  However, simply by allowing the speech recognition device to recognize the spoken speech, the user knows whether or not his speech is being slack, and if so, what kind of slack tends to be found Because it is not possible to correct the utterance of my utterance, it is difficult to learn the correct utterance method.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a speech recognition control apparatus that allows a user to easily learn a correct speech method.

  A feature of the present invention is a voice recognition control device that executes control corresponding to a recognized voice command when at least voice uttered by the user corresponds to a predetermined voice command, and inputs voice uttered by the user A voice input unit, a voice recognition unit for determining whether or not the input voice corresponds to a predetermined voice command or a voice command corresponding to the voice when the voice command is spoken, and the input voice If the speech recognition unit determines that the command corresponds to a gamanake command, the user who teaches the user the tendency of the utterance blurring specified by the lenient tendency specifying unit that identifies the user's tendency of utterance And teaching means.

  When it is determined that the input voice corresponds to a sloppy command, the user's tendency to sneak utterance is identified, and this is taught to the user so that the user can easily grasp the tendency of his utterance sloppy Therefore, the user can easily learn the correct utterance method. For example, the user can grasp the tendency of utterance blurring, such as a single sound at the beginning or end of the word becoming weak or missing, or a consonant such as “r” being missing.

  The slack tendency identifying unit includes a storage unit that stores a history of a slack command that has been recognized in the past or a trend of a slack utterance to which the slack command belongs, and refers to data in the storage unit at a predetermined number or frequency. When a slack command is recognized, the tendency to which the slack command belongs may be specified as the “spoken slack tendency”. Alternatively, the tendency to which the slack command belongs may be specified as the “spoken slack tendency” only by recognizing the slack command once.

  In the feature of the present invention, the user teaching means may notify the user of a pronunciation based on a correct voice command. The user can grasp the pronunciation based on the correct voice command without any burden.

  In the feature of the present invention, the lenient tendency specifying unit, when the speech recognition unit determines that the input voice corresponds to the lenient command, in response to the voice command corresponding to the voice when the utterance is made without slicking the lenient command. It may have a deficient part specifying unit that specifies a part where the input voice is insufficient, and the user teaching unit may teach the user the deficient part specified by the deficient part specifying unit.

  The user utters by identifying a point where the input voice is insufficient for the voice command corresponding to the voice when speaking without using the slack command, and teaching the user of the shortage part. Since it is possible to present which part of the sound is weak or missing, the user can easily learn the correct speech method. For example, when there is a tendency for utterance dullness such as the beginning or end of the word to be weak or missing, the beginning or end of the speech that is lacking in voice input to the voice command may be taught to the user.

  In the feature of the present invention, the slack tendency identifying unit inputs a voice command corresponding to a voice when a speech is spoken without a slack command when the speech recognition unit determines that the input voice corresponds to a slack command. The change part specifying part which specifies the place where the made sound is changed may be provided, and the teaching means may teach the user the change part specified by the change part specifying part.

  The user utters by specifying the location where the input voice is changed in response to the voice command corresponding to the voice when uttering without slicking the command, and teaching the user of the changed location. Since it is possible to present which part of the voice is wrong, the user can easily learn the correct speech method. For example, if there is a tendency to utter utterances where consonants such as “r” are missing, a consonant location such as “r” where the voice input in response to the voice command is changed may be taught to the user.

  In the feature of the present invention, the voice recognition unit may include a collation target deletion unit that deletes, from the collation target, a slack command that does not belong to the utterance slack tendency specified by the slack trend identification unit.

  By deleting the slack commands that do not belong to the trend of utterance slack specified by the slack trend identification unit from the collation target, the slack commands that are not necessary for the user are deleted from the collation target. The amount of data is reduced, the speech recognition rate is improved, and erroneous recognition and malfunction caused thereby are suppressed.

  In the feature of the present invention, when the voice recognition control device recognizes that the voice uttered by the user corresponds to the predetermined voice command, the voice recognition control device executes control corresponding to the recognized voice command, and the voice uttered by the user When it is recognized that the voice command corresponds to the voice command corresponding to the voice when the voice command is spoken, the control unit may execute a control corresponding to the voice command.

  According to the speech recognition control device of the present invention, the user can easily learn the correct utterance method by specifying the utterance slack and teaching it to the user.

Embodiments of the present invention will be described below with reference to the drawings. In the description of the drawings, the same portions are denoted by the same reference numerals, and description thereof is omitted.
(First embodiment)
With reference to FIG. 1, specific configurations of the speech recognition control device 10 and the controlled device 20 according to the first embodiment of the present invention will be described. The voice recognition control device 10 is a device that recognizes a command (command) by a voice spoken by a user and executes control of the controlled device 20 according to the command by the voice. Further, the voice recognition control device 10 performs control of each component in the voice recognition control device 10 based on this voice command, not limited to the control of the controlled device 20. In the embodiment of the present invention, a case where the voice recognition control device 10 controls various controlled devices 20 installed in a bathroom will be described as an example.

  Specifically, the voice recognition control device 10 determines whether or not a controller 11 that forms a user interface and a user's voice command input via the controller 11 corresponds to a predetermined voice command or a slack command. The voice recognition unit 12, the control execution unit 13 that outputs a control signal for executing control of the controlled device 20 corresponding to the voice command or the slack command recognized by the voice recognition unit 12, and output from the control execution unit 13 The control IF unit 15 that transmits the control signal to the controlled device 20, the voice synthesizer that synthesizes the voice output to the user, and the voice command verification data that can be recognized by the voice recognition control device 10 And the collation data storage unit 14 for storing collation data for the slack command and the result of determination by the voice recognition unit 12. There are, and a raw only tend specifying unit 16 which specifies the tendency of the user's utterance lazy.

  Usually, depending on the manner of utterance and individual differences, utterance slack may occur, for example, the beginning or ending of speech to be uttered may be weak, missing, or r consonants may be missing. In the embodiment of the present invention, the “name command” is a command corresponding to the voice when the voice command is spoken, and the “voice command” is the voice when the voice is spoken correctly without uttering the voice command. Corresponding command. Details of the slack command will be described later with reference to FIGS.

  The controller 11 inputs a voice uttered by the user, outputs a voice signal 40 as an electrical signal (voice signal), a voice output section 50 that outputs a voice synthesized by the voice synthesizer, and a user And a display unit 70 for displaying a predetermined screen or the like. Although not shown in FIG. 1, in this embodiment, the controller 11 further includes an operation button unit that receives a user button operation. Details of the controller 11 will be described later with reference to FIG.

  In addition, the controller 11 includes a user teaching unit 60 (user teaching unit) that teaches the user the tendency of the utterance blur specified by the slack tendency specifying unit 16. The user teaching unit 60 includes a display unit 70 that displays the tendency of speech utterance on the screen and a voice output unit 50 that guides the tendency of speech utterance by voice.

  The voice input unit 40 receives a user's speech and converts it into a voice signal, an amplifier that amplifies the voice signal, and an A / D converter that converts the amplified voice signal into a digital signal. And a noise subtracting section for removing a noise component from the digitized voice signal. The voice signal from which noise has been removed by the noise subtraction unit is transmitted to the voice recognition unit 12.

  The audio output unit 50 includes a D / A conversion unit that converts the audio signal synthesized by the audio synthesis unit into an analog signal, an amplification unit that amplifies the analog audio signal, and converts the amplified audio signal into audio. And a speaker for conversion and output.

  The display unit 70 is an LED that displays the operating status of the controlled device 20 to the user by turning on / off / flashing, and a liquid crystal that displays the operating status of the controlled device 20 to the user by an image such as a character or a picture. And a display device.

  The operation button unit includes various buttons for manually setting the operation of the controlled device 20 by a user, and includes a controller on / off switch for switching an operation on / off state of the controller 11. It is.

  The voice recognition unit 12 collates the voice signal output from the voice input unit 40 with the collation data stored in the collation data storage unit 14, and the voice input to the voice input unit 40 is a predetermined voice. It is determined whether it corresponds to a command or a slack command. Specifically, the voice recognition unit 12 compares the voice signal (speech data) output from the voice input unit 40 with the collation data stored in the collation data storage unit 14 so that the voice uttered by the user is predetermined. If the voice command or the lenient command is determined, and if it is determined that the voice command or the lenient command, the control execution unit 13 and the lenient tendency specification To the unit 16.

  The details of the check method of the namaze command are as follows. The collation data storage unit 14 stores collation data for slack commands assumed for each voice command. The speech recognition unit 12 identifies the speech signal input from the speech input unit 40 as a speech signal for each phoneme, and recognizes that the input character is, for example, (te) (e) (bi). Then, it is verified whether or not there is (te), (e), (b) in the collation data of the slack command. In the case where the collation data storage unit 14 holds voice data of “words” (te) (e) (bi) as collation data for the slack command, it is input from the voice input unit 40. The voice signal can be collated with the collation data of the direct name command. As described above, the voice recognition unit 12 may collate the voice signal input from the voice input unit 40 for each phoneme, or may collate for each command.

  Note that the voice recognition unit 12 includes a collation target deletion unit 19 that deletes a slack command that does not belong to the utterance slack tendency specified by the slack trend identification unit 16 from the collation target.

  The slack tendency identification unit 16 identifies the tendency of the user to be uttered and slack based on the determination result of whether or not the input voice corresponds to a predetermined voice command or a slack command. Usually, there are several tendencies in the utterance of utterance, such as the beginning or ending of the utterance being weak, missing, or missing r consonant. Based on the determination result of whether or not it corresponds to the command, it is specified which utterance dull tendency the user has. The tendency of utterance slander will be described later with reference to FIG.

  When the voice recognition unit 12 determines that the voice input to the voice input unit 40 corresponds to the lick command, the lick tendency specifying unit 16 responds to the voice command corresponding to the voice when the utterance is made without slicking the lick command. When the speech recognition unit 12 determines that the input speech falls under the sneak command when the speech recognition unit 12 determines that the location where the input speech is lacking, and the input speech falls under the sneak command, And a change location specifying unit 18 for specifying a location where the voice input to the voice command corresponding to the voice is changed.

  When the lacking part identifying unit 17 identifies the lacking part, the user teaching unit 60 teaches the user about the lacking part and the correct utterance method. When the changed part specifying unit 18 specifies the changed part, the user teaching unit 60 teaches the user about the changed part and the correct utterance method. If there are missing or changed parts in the input voice, teaching the user of the missing or changed parts and the correct utterance method will cause the user to speak any part of the voice that is uttered. Or which part is wrong can be presented, so that the user can easily learn the correct speech method. For example, when there is a tendency for utterance dullness such as the beginning or end of the word to be weak or missing, the beginning or end of the speech that is lacking in voice input to the voice command may be taught to the user. Alternatively, if there is a tendency to utter utterance that consonants such as “r” are missing, it is only necessary to teach the user the consonant location such as “r” in which the voice input in response to the voice command is changed. A specific example of teaching a user a shortage or change will be described later with reference to FIGS. 6 (a) and 6 (b).

  The collation target deletion unit 19 does not delete the collation data of the name command from the collation data storage unit 14, but the voice recognition unit 12 compares the voice signal (speech data) output from the voice input unit 40. From the verification data, the verification data of the slack command that is not necessary for the user is deleted. Therefore, even if the matching data of the slack command is deleted from the verification target of the voice recognition unit 12, it is still stored in the verification data storage unit 14. In this way, by deleting a slack command that does not belong to the utterance slack tendency specified by the slack trend specifying unit 16 from the collation target of the speech recognition unit 12, it is possible to delete a slack command that is not necessary for the user. Therefore, the data amount of the collation data to be collated by the voice recognition unit 12 is reduced, the voice recognition rate is improved, and erroneous recognition and malfunction due to this are suppressed.

  When the voice recognition unit 12 recognizes that the voice uttered by the user corresponds to a predetermined voice command, the control execution unit (control unit) 13 executes control corresponding to the recognized voice command, and the voice uttered by the user If the voice command is recognized to correspond to the voice command corresponding to the voice when the voice command is spoken, the control corresponding to the voice command is executed.

  The control execution unit 13 includes a microcomputer and a predetermined storage area (RAM), and controls the operation of each component of the controlled device 20 and the speech recognition control device 10 according to a predetermined program. Specifically, when the control execution unit 13 receives a predetermined signal corresponding to the voice command or the slack command recognized by the voice recognition unit 12 or receives a predetermined signal by operating the button of the operation button unit, A control signal corresponding to the voice command, slack command, or button operation is transmitted to each component 20 or the voice recognition control device 10.

  The controlled devices 20 include a lighting device 21, an air conditioning device 22, a water heater 23, a television 24, a jet jet bath device 25, and a mist sauna device 26. The lighting device 21 is a device for illuminating the interior of the bathroom with artificial light, and includes main illumination that brightens the entire bathroom and indirect illumination that indirectly irradiates light from the light source. The air conditioner 22 is attached to the wall or window of the bathroom, and the air whose temperature, humidity, and cleanness are adjusted is sent to the bathroom by rotating the blades with a motor to make the bathroom comfortable. It is a device for keeping. The jet fountain bath device 25 is a device that blows out hot water mixed with bubbles from the spouts installed at several places on the wall surface of the bathtub and hits the bather's back or legs. The mist sauna device 26 is a device that delivers mist-like water vapor that is warmed into the bathroom, and is a device that is used in a bathing method that warms the user's body by the user taking the water vapor that is delivered.

  FIG. 2 is an external view in the bathroom showing an example of the arrangement of the voice recognition control device 10 and the controlled device 20 shown in FIG. As the controlled device 20, main lighting 21a and indirect lighting 21b belonging to the lighting device 21 and air conditioning device 22 are installed on the ceiling in the bathroom, a television 24 and a mist sauna device 26 are installed on the wall surface near the bathtub 3 in the bathroom, A jet outlet 25a and a suction port 25b of the jet bath device 25 are installed in the bathtub 3 in the bathroom. A controller 11 is installed on the wall surface near the bathtub 3 in the bathroom. In addition, components other than the hot water heater 23, which is one of the controlled devices 20, the pump device of the jet jet bath device 25, the heat source device of the mist sauna device 26, and the controller of the voice recognition control device 10 are installed outside the bathroom. ing.

  The arrangement example shown in FIG. 2 is an example, and the voice recognition control device 10 and the controlled device 20 can take other layouts. Moreover, in FIG.1 and FIG.2, although the illuminating device 21, the air conditioner 22, the hot water heater 23, the television 24, the jet-jet bath apparatus 25, and the mist sauna apparatus 26 were mentioned as an example of the to-be-controlled apparatus 20, it is not restricted to this. The controlled device 20 includes electrical appliances that play music and video stored in recording media such as cassette tapes, CDs, MDs, and DVDs, and electrical appliances that users use in the bathroom, such as heating devices and personal computers. Is included.

  Next, the layout of the operation surface of the controller 11 shown in FIGS. 1 and 2 will be described with reference to FIG. On the operation surface of the controller 11, a microphone 41 of the audio input unit 40, a speaker 53 of the audio output unit 50, various operation buttons 60 a to 60 i, an LED 71 as a display unit 70, and a liquid crystal display device 72 are arranged.

  The various operation buttons 60a to 60i include a menu button 60a, a confirmation button 60b, a return button 60c, a cross key 60d, a priority button 60e, a follow-up button 60f, a bath automatic button 60g, a call button 60h, and a controller on / off switch 60i. Among these buttons 60a to 60i, the priority button 60e, the follow-up button 60f, the automatic bath button 60g, and the call button 60h are used for controlling the water heater 23. The other buttons and switches are used not only for the hot water heater 23 but also for controlling each component of the controlled device 20 and the speech recognition control device 10. As described above, the controller 11 is configured to function as both a bathroom remote controller that controls the controlled device 20 by a switch operation and the control panel of the voice recognition control device 10.

  Specifically, the priority button 60e is a button used when it is desired to set a hot water supply temperature or a shower temperature in the bathroom. In general, water and hot water are used not only in the bathroom but also in the kitchen. For this reason, even if the hot water supply temperature and the shower temperature of the water heater 23 are set, if water or hot water is used in other places, the actual hot water supply temperature or the shower temperature may be shifted. Therefore, by pressing the priority button 60e, it is possible to give priority to the bathroom over other places, and to prevent the actual hot water supply temperature and shower temperature from being shifted. When the priority button 60e is pressed, a priority mark (not shown) is displayed on the display unit 70 by a method such as turning on the LED 71 or displaying the priority state on the liquid crystal display device 72.

  The chasing button 60f is a button used when raising the temperature of hot water in the bathtub. When the tracking button 60f is pressed, a tracking mark (not shown) is displayed on the display unit 70 in the same manner as the priority mark. The bath automatic button 60g is a button used when hot water is poured into the bathtub with a preset amount and temperature of hot water. When the automatic button 60g is pressed, an automatic mark (not shown) is displayed on the display unit 70 in the same manner as the priority mark.

  The call button 60h is a button used when making a call with a kitchen remote controller installed outside the bathroom, for example, in a kitchen. When the call button 60h is pressed, a call mark (not shown) is displayed on the display unit 70 in the same manner as the priority mark.

  The menu button 60a is a button for setting operations of the controlled device 20 and the voice recognition control device 10 by manual input. When the menu button 60a is pressed, the operation items of the controlled device 20 and the voice recognition control device 10 (for example, air conditioner off, TV power on, TV channel + 1, mist sauna device on, voice recognition unit on, etc.) are displayed on the liquid crystal display. A plurality of items are displayed on the device 72. The user selects one action item by operating the cross key 60d from the plurality of action items.

  The confirmation button 60b is a button that is pressed when the controlled device 20 and the voice recognition control device 10 execute the operation of the operation item selected by operating the cross key 60d. The return button 60c is a button used when returning the screen displayed on the liquid crystal display device 72 to the previous state. For example, when only a part of the operation items can be displayed on the liquid crystal display device 72, it is possible to move to the next screen by operating the cross key 60d and display the remaining operation items. If the return button 60c is pressed, the transitioned screen can be restored and the operation items of the previous screen can be displayed on the liquid crystal display device 72. The cross key 60d is a button used for temperature setting of hot water supply temperature or shower temperature, setting of hot water volume, selection of operation items, selection of on / off, and the like.

  The controller on / off switch 60i is a button for turning on or off the power supply of the controller 11. Each time the controller on / off switch 60i is pressed, the controller 11 is turned on or off. When the controller 11 is turned off by the controller on / off switch 60i, the display on the liquid crystal display device 72 is erased, the control of the controlled device 20 and the voice recognition control device 10 through the switch operation of the controller 11 is disabled, and Control of the controlled device 20 and the voice recognition control device 10 by voice recognition is also invalidated.

  The above-described control by the button operation of the various operation buttons 60a to 60i can be executed in the same manner even if the voice recognition function of the user's uttered voice is used. That is, the collation data storage unit 14 stores collation data of voice commands and slack commands corresponding to the control equivalent to the button operation of the controller 11 described above, and the voice recognition unit 12 is output from the voice input unit 40. By comparing the voice signal (speech data) with the collation data stored in the collation data storage unit 14, voice commands corresponding to the control equivalent to the button operations of the various operation buttons 60 a to 60 i and the namare Can recognize commands.

  The liquid crystal display 72 displays the time, the amount and temperature of hot water in the bathtub, the hot water supply temperature, the shower temperature, and the like. Further, the liquid crystal display device 72 displays the tendency of utterance blurring specified by the trend tendency specifying unit 16 on the screen. In addition to the screen display by the liquid crystal display device 72 or in place of the screen display, the same content may be guided from the speaker 53 by voice. In this way, the user can easily grasp his / her utterance tendency by teaching the user the utterance / smoothing tendency specified by the sloppy tendency specifying unit 16 through screen display and voice guidance.

  Next, with reference to FIG. 4 and FIG. 5, the tendency of speech utterance specified by the lenient tendency specifying unit 16 will be described. The slack tendency identifying unit 16 identifies the utterance slack tendency of the user based on the determination result of whether or not the input voice corresponds to the voice command or the slack command. As shown in FIG. 4, the tendency of utterance sanctions includes, for example, “beginning weakening (smoothing tendency 1)” in which the beginning of the speech to be uttered is weak or missing, or the ending of the speech to be uttered is weakened or missing. "End weakening (smoothing tendency 2)" and "r missing (smoothing tendency 3)" where r consonants are missing.

  As shown in FIG. 5, for example, when the voice command corresponding to the control content of “turning on the power of the television 24” is “turn on TV”, among the slack commands corresponding to the “turn on TV” , The name commands belonging to “Initial weakening (named tendency 1)” are “Add Levi”, and the name commands belonging to “Initial weakening (Named tendency 2)” are “Add Lebi”, “ The slack command belonging to “missing r (sloping tendency 3)” is “put shrimp”.

  Similarly, when the voice command corresponding to the control content “turn on the lighting device 21” is “Turn on the light”, among the slack commands corresponding to the “Turn on the light”, The lazy command belonging to “(Laze tendency 1)” is “Turn on the scale”, and the lazy command belonging to “Lack of endings (Lack of trend 2)” is “Take a light”, and “missing r” (sloping tendency) 3) The slander command belonging to “” is “with red”.

Although illustration is omitted, in addition to this, the slack tendency specifying unit 16 also specifies the tendency of utterance slack as follows.
(A) “ei” changes to “ee”. Example: “Tashishi (stop)” changes to “Teshishi”, etc.
(B) “ou” changes to “oo”. Example: “Boko (home school)” changes to “Bokoo”
(C) “shi” and “hi” are interchanged. Examples: “sheep” and “sheep”
(D) Others that cannot be ruled. Examples: “Zenin (all)” changes to “Zein”, “Bai (if)” changes to “Bai”, etc.

  In addition, in FIG. 5, as an example of weakening of the beginning and ending, a case where one sound of the beginning and ending is weakened, but a “name command” in which two or more sounds of the beginning and ending are weakened is prepared. It does not matter. Next, FIG. 6 (a) shows an example of utterance blurring in which the last three sounds are weakened.

  FIG. 6A and FIG. 6B show screen examples of the liquid crystal display device 72 that displays the tendency of utterance slack and a lacking part or a changed part to the user. The screen example of FIG. 6A shows a voice command corresponding to the voice when the voice recognition unit 12 recognizes that the input voice corresponds to the lick command “Telebi” and speaks without singing “Telebi”. This message is displayed when the lacking part identifying unit 17 identifies a place where “telebi” is insufficient for (for example, “put on TV” or “get off TV”). In the screen example of FIG. 6A, it is clearly shown that the user has a slack tendency 2 (weak ending). In addition, since the voice command corresponding to the voice when uttering “Telebi” is not narrowed down to one, the shortage point is not specified as one, but the device 10 recognizes it instead. The voice “Telebi” is clearly indicated, and the user is instructed in the correct utterance method so that the subsequent words are uttered to the end. In addition, in the screen example of FIG. 6A, candidates for subsequent words (for example, “tick” and “kake”) may be added and displayed.

  In the screen example of FIG. 6B, the voice recognition unit 12 recognizes that the input voice corresponds to the lick command “Take shrimp” and utters “shrimp” without slap. This is displayed when the changed part specifying unit 18 specifies a part that has been changed in response to the voice command “Telebi on” corresponding to the voice. In the screen example of FIG. 6B, it is clearly shown that the user has a slack tendency 3 (r missing). In addition, it indicates that the input voice is recognized as “with shrimp”, and the user is instructed on the correct utterance method to pronounce r clearly.

  Next, an example of the operation procedure of the voice recognition control device 10 of FIG. 1 will be described with reference to FIG.

  (A) First, in step S101, a voice prompt is input to the voice input unit 40 by displaying a screen prompting the user to speak on the liquid crystal display device 72 or outputting a voice guidance prompting the user to speak from the speaker 53. Prompt the user to

  (B) Proceeding to step S103, it is determined whether or not the user's speech is input to the voice input unit 40. If the user's speech is input and a speech signal is output to the speech recognition unit 12 (YES in S103), the process proceeds to step S105. If the speech is not input (NO in S103), the process returns to step S101, and again. , Prompt the user for voice input.

  (C) In step S105, the voice recognition unit 12 collates the collation data stored in the collation data storage unit 14 with the voice signal output from the voice input unit 40, and the input voice is a predetermined value. It is determined whether or not a voice command or a slack command is applicable. If it is determined that it corresponds to the voice command or the lenient command (speech recognition is successful) (YES in S105), a predetermined signal corresponding to the voice command or the lenient command is output to the lenient tendency specifying unit 16, and the process proceeds to step S107. . On the other hand, if it is not determined that the command corresponds to a voice command or a slack command (speech recognition has failed) (NO in S105), the fact that voice recognition cannot be performed is displayed on the liquid crystal display device 72, and then the process returns to S101.

  (D) In step S107, the trend tendency identifying unit 16 identifies the tendency of the user to utter and blur based on the determination result in step S105. Thereafter, the process proceeds to step S109. If the input voice has a tendency to be distorted (YES in S109), the process proceeds to step S111, where the user teaching unit 60 determines the tendency of the utterance to be distorted specified by the lenient tendency specifying unit 16 (smooth tendency 1, 2, 3,. ..) is taught to the user, and the flowchart of FIG. 8 ends. If the input voice does not tend to be distorted (NO in S109), step S111 is not performed and the flowchart of FIG. 8 ends.

  As described above, according to the first embodiment of the present invention, the following operational effects can be obtained.

  From the determination result of whether or not the voice input to the voice input unit 40 corresponds to a predetermined voice command or a slack command, the slack tendency identifying unit 16 identifies the tendency of the user's speech slack, and the user teaching unit 60 is the user. Since the user can easily grasp his / her utterance tendency, the user can easily acquire the correct utterance method. For example, the user can grasp the tendency of utterance blurring, such as a single sound at the beginning or end of the word becoming weak or missing, or a consonant such as “r” being missing.

The voice recognition unit 12 includes a collation target deletion unit 19 that deletes, from a collation target, a slack command that does not belong to the utterance slack tendency specified by the slack trend identification unit 16, so that the unrecognized simple command is recognized by the user. Since the data is deleted from the verification target of the unit 12, the amount of verification data to be verified is reduced, the speech recognition rate is improved, and erroneous recognition and malfunction caused thereby are suppressed.
(Second Embodiment)
With reference to FIG. 9, an example of an operation procedure of the speech recognition control apparatus 10 according to the second embodiment will be described. Here, when it is recognized that there is a tendency to be slack, the procedure for determining the presence or absence of a missing part and a changed part and teaching the user of the missing part and the changed part and the correct speech method will be described.

  (A) Since the processing operations in steps S201 to S209 in FIG. 9 are the same as those in steps S101 to S109 in FIG.

  (B) In step S211, the lacking part specifying unit 17 is a part where the input voice is insufficient for the voice command corresponding to the voice when the speech recognition unit 12 recognizes the spoken command without sneaking. Is identified. When the insufficient part is specified (YES in S211), the process proceeds to step S213, and the user teaching unit 60 teaches the user about the insufficient part and the correct speech method. Thereafter, the process proceeds to step S215. If the lacking part is not specified (NO in S211), the process proceeds to step S215.

  (C) In step S215, the changed part specifying unit 18 is a part where the input voice is changed with respect to the voice command corresponding to the voice when the utterance command recognized by the voice recognition unit 12 is spoken. Is identified. When the changed part is specified (YES in S215), the process proceeds to step S217, where the user teaching unit 60 teaches the changed part and the correct speech method to the user, and the flowchart of FIG. 9 ends. If the change location is not specified (NO in S215), step S217 is not performed and the flowchart of FIG. 9 ends.

  As described above, according to the second embodiment of the present invention, the following operational effects can be obtained.

  The user utters by identifying a point where the input voice is insufficient for the voice command corresponding to the voice when speaking without using the slack command, and teaching the user of the shortage part. Since it is possible to present which part of the sound is weak or missing, the user can easily learn the correct speech method.

  The user utters by specifying the location where the input voice is changed in response to the voice command corresponding to the voice when uttering without slicking the command, and teaching the user of the changed location. Since it is possible to present which part of the voice is wrong, the user can easily learn the correct speech method.

  As described above, the present invention has been described in terms of two embodiments, but it should not be understood that the discussion and drawings that form part of this disclosure limit the present invention. From this disclosure, various alternative embodiments, examples, and operational techniques will be apparent to those skilled in the art.
