  When performing operations such as medical sites, construction sites, building sites, shipyards, machinery manufacturing sites, or automobile operations, error prevention and safety measures in each business are very important matters. Various methods have been adopted.

  One method of preventing mistakes and safety measures in each business is, for example, “voice check” such as pointing and calling. “Voice check” is a method of safety check called by various names such as pointing call, pointing call, confirmation call, commentary driving, etc., and is usually performed with “pointing action”.

  The above-mentioned “voice check” is surely effective if executed, but whether or not to perform “voice check” is mostly left to the operator himself / herself. Therefore, there is a problem that when the worker gets used to the work, the person often neglects or forgets to confirm the voice.

  In addition, there is a case where an administrator exists in the actual business location and manages / supervises the status of the worker's “voice confirmation”. However, it is practically difficult for an administrator to wait for a long time at the business location only for such management. Therefore, it is difficult for the manager to accurately grasp and evaluate the situation of the “voice check” of the worker, and there is a problem that it is not possible to appropriately provide improvement guidance for such work.

  From the above, in the past, “confirming the voice” will be left to the worker as a result, and “confirmation of the voice” will not be established in the work, and the manager will also evaluate and give guidance for improvement. Was very difficult.

  By the way, the technique of patent document 1 is known as a system which performs inspection work using voice recognition. However, this technique merely checks and confirms the content of the voice, and does not perform evaluation or guidance for improvement on “voice check”.

<First embodiment>
First, the business support system according to the first embodiment of the present invention will be described. FIG. 1 is a schematic diagram showing an example of an apparatus constituting the business support system according to the first embodiment of the present invention. Specifically, a business support system configured using the mobile terminal device 1 is shown. The mobile terminal device 1 (corresponding to the “business support system” of the present invention) is configured to be portable when an operator performs various business operations. For example, it is configured such that it can be inserted into a breast pocket of an outerwear. The business support system is configured so as to be able to appropriately perform evaluation and guidance for improvement of “voice check” performed by the worker.

  As shown in FIG. 1, the portable terminal device 1 (business support system) according to the present embodiment includes a voice input unit 11, a voice recognition unit 12, a phrase identification unit 13, a phrase evaluation unit 14, an evaluation storage unit 15, and a It has a clear transmission means 16. For example, a mobile phone, a PHS, or a PDA can be used as the mobile terminal device 1 in addition to the case where the mobile terminal device 1 is configured as a terminal (dedicated terminal) dedicated to the business support system.

  The voice input means 11 is used to input voice when the operator performs “voice check”, and is configured using a microphone or the like (for example, an earphone microphone or the like). In the case of a mobile phone, PHS, or the like, since a microphone is provided in advance, when using a mobile phone or the like, the voice input means 11 is configured using the microphone provided in advance. Note that when an earphone microphone is used, a microphone part as a part thereof corresponds to the voice input unit 11.

  The voice recognition means 12 is for recognizing the voice input via the voice input means 11, and this voice recognition means 12 is configured using a voice recognition engine or the like. Here, the speech recognition engine is software (speech recognition software) that can convert speech input via the speech input means 11 into text, or operate an application with the input speech. ).

  The phrase identifying means 13 identifies whether or not the input speech includes a phrase (word or phrase) used in “voice check” (corresponding to “predetermined phrase” of the present invention). Means. In the present embodiment, data of this phrase (predetermined phrase) (hereinafter also referred to as “predetermined phrase database”) is stored in advance in a memory (storage means) in the mobile terminal device 1. The phrase identifying unit 13 compares the phrase recognized (converted into characters) using the speech recognition engine and the phrase (predetermined phrase) in the predetermined phrase database stored in the memory, and receives the input speech. It is determined whether or not a predetermined phrase is present.

  The phrase evaluation means 14 is a means for evaluating each of the phrases in the input speech (phrases determined to be a predetermined phrase by the phrase identification means 13). In the present embodiment, data (hereinafter also referred to as “evaluation database”) relating to evaluation (weighting) for each word (predetermined word) is stored in advance in a memory (storage means) in the mobile terminal device 1. . That is, the phrase evaluation means 14 performs evaluation for each input phrase (predetermined phrase) using the evaluation database.

  The evaluation storage means 15 is a location (memory) that stores an input word / phrase (predetermined word / phrase), various data at the time of input (input date / time, etc.) and an evaluation result in association with each other. That is, in the memory constituting the evaluation storage means 15, a database (a database including the input date and time, evaluation results, etc.) relating to the input phrase (predetermined phrase) is configured.

  When the voice recognition means 12 recognizes the input of the voice but the predetermined word / phrase cannot be identified in the input voice, the unclear transmission means 16 (hereinafter referred to as “unclear”). It is a means for transmitting to the worker. As this “when the predetermined phrase cannot be identified in the input speech”, the phrase identifying means 13 cannot identify the predetermined phrase due to the influence of the sound generation, surrounding noise, etc., although the speech is input, There are cases where voice input has been made but a predetermined word / phrase has not been input correctly, or an erroneous input has been made due to ambient noise. As a method of transmitting to the worker that the unclearness is unclear by the unclear transmission means 16, specifically, when transmitting by sound, transmitting by vibration, transmitting by video, or these methods are used. For example, it may be transmitted in combination. Therefore, the ambiguity transmission means 16 according to the present embodiment is configured using at least one of a speaker, vibration generation means (motor or vibrator), and a display.

  Although not particularly shown in FIG. 1, the mobile terminal device 1 according to the present embodiment is naturally provided with various buttons and switches for operating the mobile terminal device 1. Using these buttons and the like, power ON / OFF and adjustment of each part (for example, volume adjustment of a speaker (unclear transmission means 16), etc.) are performed. Moreover, when using a mobile phone etc. as the portable terminal device 1 concerning this embodiment, it has a structure and function as a general mobile phone as a matter of course.

  Next, using FIG. 2 in addition to FIG. 1, a method of using the mobile terminal device 1 according to the present embodiment will be described. FIG. 2 shows a flowchart when the business support system (mobile terminal device 1) according to the first embodiment of the present invention is used. Here, a case where the mobile terminal device 1 is used when driving a car as a business will be described as an example.

  When the portable terminal device 1 according to the present embodiment is used, the worker wears the portable terminal device 1 at a place where the voice of the worker reaches (a place where the voice input means 11 picks up the voice of the worker). . For example, it is worn on the shoulder or chest of the operator. When the voice input unit 11 is configured using an earphone microphone or the like connected to the mobile terminal device 1 (main body), the mounting position of the mobile terminal device 1 is not particularly limited.

  When an operator operates the power switch or the like (not shown) of the mobile terminal device 1 with the mobile terminal device 1 mounted thereon, the mobile terminal device 1 is activated (step S201). It will be in an input standby state (step S202, S208). That is, the portable terminal device 1 repeats the voice input loop (S202, S208) until the voice input unit 11 confirms any voice input (until “Yes” is determined in S203), and enters the standby state. Will be maintained. In the present embodiment, whether or not a voice is input is determined using the voice recognition means 12.

  For example, when the operator wearing the mobile terminal device 1 gets into the automobile, the operator gets on the vehicle after performing “voice check” such as “frontward reed” and “rearward reed”. Then, when the voice recognition unit 12 constituting the mobile terminal device 1 detects (recognizes) “voice” input via the voice input unit 11, it follows the flowchart of FIG. 2 (determined as “Yes” in S 203). Then, in the mobile terminal device 1, the processing after step S204 is performed. On the other hand, in the case where the voice recognition unit 12 cannot detect (recognize) the “voice” input (“No” in S203) even though the worker utters “voice”, the mobile terminal device 1 The voice input loop (S202, S208) will be repeated.

  Even during the operation after the worker gets in the car, the worker performs “voice check” such as “speed limit 40, speed reed”, “lane change, rear reed” as necessary. Each time “voice check” is performed, the voice recognition unit 12 of the mobile terminal device 1 determines whether or not a voice input has been made (S203). Then, based on the determination result, the processing after step S204 or the voice input loop (S202, S208) is performed.

  If it is determined by the voice recognition means 12 that the voice input is made through the voice input means 11 ("Yes" is determined in S203), then the phrase identification means 13 is used to It is determined whether or not a “predetermined phrase” exists in the input voice (step S204). As described above, in the present embodiment, the predetermined phrase database is stored in the memory in the mobile terminal device 1 and is recognized by the phrase recognition unit 13 using the speech recognition unit 12 (speech recognition engine). The phrase (converted into characters) (speech input phrase) is compared with the predetermined phrase in the predetermined phrase database, and based on the result, whether or not the predetermined phrase exists in the input speech Is determined (S204).

  If the phrase identifying unit 13 determines that a predetermined phrase is present in the input voice (“Yes” in S204), then the processing from step S205 is performed, and the predetermined phrase does not exist. Is determined (in the case of “No” in S204), unclear transmission processing is performed (step S207).

  The unclear transmission process is a process of transmitting to the operator that no clear voice input has been made using the unclear transmission means 16 constituting the mobile terminal device 1. This ambiguity transmission process (S207) is performed when “speech” input has been made, but the phrase identification means 13 cannot identify a predetermined phrase in the speech due to the influence of the worker's utterance, surrounding noise, etc. , A process of transmitting to the operator that the input voice is unclear using a speaker, vibration generating means, display, or the like. That is, it is a process of transmitting to the worker that the voice input to the worker is unclear using sound, vibration, or an image. For example, when a part of the mobile terminal device 1 according to the present embodiment (the voice input unit 11 and the unclear transmission unit 16) is configured with an earphone microphone, the sound from the earphone unit that forms the unclear transmission unit 16 is used. The operator is informed that the input voice is unclear (S207). After the unclear transmission process is performed, the processes after step S202 are repeated.

  When the phrase identifying unit 13 determines that a predetermined phrase exists in the input voice (in the case of “Yes” in S204), the phrase evaluation unit 14 is used to evaluate the input voice. Performed (step S205). As described above, the phrase evaluation means 14 evaluates each of the phrases in the input speech (phrases determined to be predetermined phrases by the phrase identification means 13). Means to do. In the present embodiment, an evaluation database relating to evaluation (weighting) for each predetermined phrase is stored in advance in a memory (storage means) in the mobile terminal device 1, so that this evaluation data and the input predetermined phrase are used. Then, the phrase evaluation unit 14 evaluates a predetermined phrase in the input voice (S205).

  For example, in the evaluation database, the predetermined words “front”, “rear”, “40” in the input speech are “2 points”, the predetermined words “limit speed” are “3 points”, “Yoshi”. The word / phrase stores data related to evaluation (evaluation point) for each predetermined word / phrase, such as “1 point”. Then, in the phrase evaluation means 14, evaluation (calculation of evaluation points) is performed on the worker's voice input ("voice check") using the predetermined phrase that the worker inputs by voice and the evaluation database. (S205).

  After the phrase evaluation means 14 evaluates the voice input by the operator, the evaluation storage means 15 inputs the predetermined phrase and various data (input date and time) at the time of input, and the evaluation result ( (Results obtained by the phrase evaluation means 14) are associated with each other, and tabulation management regarding a predetermined phrase or the like is performed (step S206). That is, in the memory that constitutes the evaluation storage means 15, a database (a database including the input date and time, evaluation results, etc.) relating to the input predetermined word / phrase is configured.

  In this evaluation storage means 15, for example, the “predetermined phrase” actually input, the input “date and time”, the “evaluation point” calculated by the phrase evaluation means 14, every predetermined time (for example, every hour) “Total Evaluation Points”, “Total Evaluation Points” per day, “Total Evaluation Points” per week, “Total Evaluation Points” per month, Blank time (time without voice input) ), Statistical data regarding the type of the input “predetermined phrase”, geometric average of evaluation points, and the like.

  After performing the aggregation management (evaluation result aggregation processing performed by the phrase evaluation unit 14) in the evaluation storage unit 15, the processes after step S202 are performed again.

  Since the business support system (mobile terminal device 1) according to the first embodiment of the present invention is configured and functions as described above, the following effects can be obtained.

  According to the present embodiment, when the worker carries such a business support system (mobile terminal device 1), the voice confirmation performed by the worker is evaluated and stored without the presence of an administrator or the like. be able to. That is, based on the evaluation / storage result of the mobile terminal device 1, the manager can accurately grasp and evaluate the situation of the operator's “voice check”. Therefore, it is possible for managers to conduct evaluations and guidance for improvement regarding “voice check”, so “voice check” is not left to the operator, and it is effective to establish “voice check” within the work. Can proceed.

  In addition, according to the present embodiment, since the business support system is configured by a single mobile terminal device 1, it is possible to provide a business support system that is convenient for an operator to carry.

  Further, although not described in the above embodiment, the mobile terminal device 1 is configured so that the data in the internal evaluation storage means 15 can be transferred to an external PC (personal computer) or the like as necessary. May be. Specifically, a USB terminal or the like may be provided in the mobile terminal device 1 so that data in the mobile terminal device 1 (evaluation storage unit 15) can be directly transferred to a PC or the like. According to such a configuration, it becomes possible to evaluate and analyze the data obtained using the mobile terminal device 1 in detail on the PC, and the evaluation and improvement guidance of “voice check” are more effective. Can be done automatically.

  The voice recognition means 32 constituting the second portable terminal device 30 is for recognizing the voice inputted through the voice input means 31, and this voice recognition means 32 is a voice recognition engine (voice recognition software). ) And the like.

  The phrase identifying means 33 constituting the second mobile terminal device 30 determines whether or not a phrase (corresponding to the “predetermined phrase” of the present invention) used in “voice check” is included in the input voice. It is a means to identify. In the present embodiment, data (predetermined phrase database) relating to this phrase (predetermined phrase) is stored in advance in a memory (storage means) in the mobile terminal device 1. The phrase identifying unit 33 compares the phrase recognized (converted into characters) using the speech recognition engine with the phrase (predetermined phrase) in the predetermined phrase database stored in the memory, and receives the input speech. It is determined whether or not a predetermined phrase is present.

  The unclear transmission means 36 constituting the second portable terminal device 30 recognizes that when the voice recognition means 32 recognizes the input of the voice but cannot identify a predetermined word in the input voice (unclear This is a means for communicating to the worker. As the case where “the predetermined phrase cannot be identified in the input speech”, the phrase identifying means 33 cannot identify the predetermined phrase due to the influence of the sound generation, surrounding noise, etc. although the speech is input, There are cases where voice input has been made but a predetermined word / phrase has not been input correctly, or an erroneous input has been made due to ambient noise. Specifically, the unclear transmission means 36 transmits an unclearness to the worker as a method of transmitting by sound, transmitting by vibration, transmitting by video, or these methods. For example, it may be transmitted in combination. Therefore, the ambiguity transmission means 36 according to the present embodiment is configured using at least one of a speaker, vibration generation means (motor or vibrator), and a display.

These buttons and the like are used to turn the power on / off and adjust each part (for example, adjust the volume of the speaker (unclear transmission means 36)). Moreover, when using a mobile phone etc. as the 2nd portable terminal device 30 concerning this embodiment, naturally, it has a structure and function as a general mobile phone.

  Next, in addition to FIG. 3, the usage method of the 2nd portable terminal device 30 concerning this embodiment, etc. are demonstrated using FIG. FIG. 4 shows a flowchart when the business support system according to the second embodiment of the present invention is used. Here, the case where the second portable terminal device 30 is used when driving a car as a business will be described as an example. In addition, since there is a portion that is substantially the same as that of the first embodiment described above, description thereof is omitted, and here, a portion that is different from the first embodiment is mainly described.

  When the operator wears the second mobile terminal device 30 and operates the power switch or the like (not shown) of the second mobile terminal device 30 to activate the second mobile terminal device 30 (step S401), The two portable terminal devices 30 enter a voice input standby state (steps S402 and S408). That is, the second portable terminal device 30 repeats the voice input loop (S402, S408) and waits until some voice input is confirmed by the voice input unit 31 (until "Yes" is determined in S403). The state will be maintained. In the present embodiment, whether or not voice is input is determined using the voice recognition means 32.

  For example, when the operator wearing the second mobile terminal device 30 gets into the car, he / she gets on after performing “speech confirmation” such as “frontward reed” and “rearward reed”. Then, when the voice recognition unit 32 configuring the second portable terminal device 30 detects (recognizes) the “voice” input via the voice input unit 31, it is determined as “Yes” in the flowchart of FIG. 4 (S403). Then, in the second portable terminal device 30, the process after step S404 is then performed. On the other hand, in the case where the voice recognition means 32 cannot detect (recognize) “voice” input (“No” in S403) even though the worker utters “voice”, the second portable terminal device 30 repeats the voice input loop (S402, S408).

  Even during the operation after the worker gets in the car, the worker performs “voice check” such as “speed limit 40, speed reed”, “lane change, rear reed” as necessary. Each time “voice check” is performed, the voice recognition unit 32 of the second portable terminal device 30 determines whether or not a voice input has been made (S403). Then, based on the determination result, the processing after step S404 or the voice input loop (S402, S408) is performed.

  If it is determined in the voice recognition means 32 that the voice input is made through the voice input means 31 (“Yes” in S403), then the phrase identification means 43 is used to It is determined whether or not a “predetermined phrase” exists in the input voice (step S404). Also in the present embodiment, as in the first embodiment, a predetermined phrase database is stored in the memory in the second portable terminal device 30, and the speech recognition means 32 (voice recognition engine) is used by the phrase identification means 33. The words (converted into characters) recognized in speech (the words input by voice) and the predetermined words in the predetermined word database are compared, and based on the result, the predetermined words are present in the input voice Is determined (S404).

  If the phrase identifying unit 33 determines that the predetermined phrase is present in the input voice (“Yes” in S404), then the process from step S409 is performed, and the predetermined phrase does not exist. Is determined (in the case of “No” in S404), an unclear transmission process is performed (step S407).

  As described in the first embodiment, the unclear transmission process means that a clear voice input is not made to the worker using the unclear transmission means 36 constituting the second mobile terminal device 30. Is a process of transmitting. This ambiguity transmission process (S407) is performed when “speech” input has been made, but the phrase identification means 43 cannot identify a predetermined phrase in the speech due to the influence of the worker's utterance method, surrounding noise, etc. , A process of transmitting to the operator that the input voice is unclear using a speaker, vibration generating means, display, or the like. That is, it is a process of transmitting to the worker that the voice input to the worker is unclear using sound, vibration, characters, images, or the like. For example, when a part of the second portable terminal device 30 according to the present embodiment (the voice input unit 31 and the unclear transmission unit 36) is configured by an earphone microphone, the earphone unit that forms the unclear transmission unit 36 The sound is transmitted to the worker that the input voice is unclear (S407). After the unclear transmission process is performed, the processes after step S402 are repeatedly performed.

  When the phrase identifying unit 33 determines that the predetermined phrase is present in the input voice (“Yes” in S304), information regarding the input predetermined phrase is transmitted via the Internet 44. Are transmitted to the second computer 42 functioning as a server (database server) (step S409). For example, when the second mobile terminal device 30 is configured by a mobile phone, data transfer by HTTP communication is performed between the second mobile terminal device 30 and the database server (second computer 42). Then, using the word evaluation means (not shown) provided in the second computer 42, the transferred data (input voice) is evaluated.

  The “evaluation” performed in the second computer 42 is basically the same as that described in the first embodiment. As described above, the phrase evaluation unit evaluates each phrase in the input voice (the phrase determined to be a predetermined phrase by the phrase identification unit 33). Means. Also in the present embodiment, as in the first embodiment, an evaluation database relating to evaluation (weighting) for each predetermined phrase is stored in advance in a memory (storage means) in the second computer 42. Using the data and the inputted predetermined word / phrase, the word / phrase evaluating means evaluates the predetermined word / phrase in the inputted voice.

  For example, in the evaluation database, the predetermined words “front”, “rear”, “40” in the input speech are “2 points”, the predetermined words “limit speed” are “3 points”, “Yoshi”. The word / phrase stores data related to evaluation (evaluation point) for each predetermined word / phrase, such as “1 point”. In the word evaluation means, evaluation (calculation of evaluation points) is performed on the worker's voice input (“voice check”) using the predetermined word / phrase input by the worker and the evaluation database. It becomes.

  After the phrase evaluation means evaluates the voice input by the operator, the evaluation storage means (not shown) in the second computer 42 receives the input predetermined words and various data (input date and time). Etc.) and their evaluation results (results obtained by the phrase evaluation means) are associated with each other and tabulation management relating to predetermined phrases is performed. That is, a database (a database including input date and time, evaluation results, etc.) relating to the input predetermined word / phrase is configured in the memory constituting the evaluation storage means.

  In this evaluation storage means, for example, “predetermined phrases” actually input, “date and time” input, “evaluation points” calculated by the phrase evaluation means, “every hour (for example, every hour)” “Total evaluation points”, “Total evaluation points” per day, “Total evaluation points” per week, “Total evaluation points” per month, Blank time (time when voice input is not performed) Data, statistical data related to the type of the input “predetermined phrase”, geometric average of evaluation points, and the like are stored.

  Note that, in the business support system according to the present embodiment, unlike the first embodiment, evaluation and totalization management regarding input voice are performed using the second computer 42 instead of the mobile terminal device. That is, the business support system according to the present embodiment performs evaluation and centralized management using a device capable of high-capacity and high-speed processing. Therefore, according to this embodiment, compared with the first embodiment, it is possible to perform detailed, detailed evaluation, analysis, and tabulation management in real time with respect to the input voice.

  In the present embodiment, after the input information related to the predetermined phrase is transmitted to the second computer 42 functioning as a server (database server) via the Internet 44 (step S409), the steps after step S202 are performed again. Processing will be performed.

  Since the business support system according to the second embodiment of the present invention is configured and functions as described above, the following effects can be obtained.

  According to the present embodiment, as in the case of the first embodiment, the operator carries the second portable terminal device 30 so that the voice confirmation performed by the worker can be confirmed even if there is no administrator or the like. Evaluation, storage, and the like can be performed by the second computer 42. That is, based on the evaluation etc./stored result obtained by using the second portable terminal device 30, the manager can accurately grasp and evaluate the situation of the operator's “voice check”. Therefore, it is possible for managers to conduct evaluations and guidance for improvement regarding “voice check”, so “voice check” is not left to the operator, and it is effective to establish “voice check” within the work. Can proceed.

  Moreover, according to this embodiment, since the specific evaluation etc. regarding a predetermined phrase are performed using the 2nd computer 42, compared with 1st embodiment, a portable terminal device (2nd portable terminal) The configuration of the device 30) can be further simplified.

  Note that the present invention is not limited to the above-described embodiment, and can be implemented with various modifications as necessary within the scope that can meet the spirit of the present invention. It is included in the technical scope of the present invention.

  For example, the mobile terminal devices 1 and 30 in the above-described embodiments may be provided with “speech instruction means” and the like as necessary. This “voice out instruction means” is for urging the operator to perform “voice check”. For example, the voice output means or the like (sound output using a stored voice file or voice synthesis) Possible device). The voice output instruction means operates according to a predetermined timing, a random timing, or the execution status of the “voice check” by the worker (for example, when “voice check” is not performed for 1 hour). Is configured to do. For example, via voice output means, etc. “Let's make a voice check.” “Do you make a voice check?” “No voice check has been done for 1 hour.” “The speed limit is It is configured to transmit a message such as “how many kilometers?” To the worker, and to encourage the worker to perform “voice check”.

  In addition, the method of transmitting a message to the worker by this “voice out instruction means” is not limited to “voice”, and any method can be used as long as it can be transmitted to the worker, such as image information, text information, vibration by a vibrator, etc. May be. That is, the “speech output instruction unit” is not limited to the case of being configured by the audio output unit, and may be configured by using a display, a vibration generator, or the like. As a matter of course, these (voice output means, display, etc.) may be combined to constitute a “voice output instruction means”.

  Furthermore, this “voice out instruction means” enhances the effect of acting on the operator (driver in the above embodiments) by setting various specific voice colors, speaking methods, appearances, facial expressions, etc. Can do.

  In the above-described embodiment, the case where the mobile terminal devices 1 and 30 are dedicated terminals or configured using a mobile phone or the like has been described, but the present invention is limited to this configuration. is not. Therefore, for example, a component of the business support system may be added to the car navigation system. Furthermore, for example, when business using a video camera is performed, components of the business support system may be added to the video camera. That is, when business is performed using any device, it is preferable to add the components of the business support system to the device. According to this preferable configuration, it is possible to use the business support system without carrying a new device or the like, and it is possible to appropriately perform “voice check” evaluation and improvement guidance.

  Further, in the above-described embodiment, the case where “unclear transmission means” is provided to transmit the fact when a clear voice input is not made has been described, but the present invention is not limited to this configuration. Absent. That is, the present invention is not limited to a configuration that positively informs the worker that it is “unclear”, but may be a configuration that positively notifies the worker that it is “clear”. That is, when it is determined that a predetermined word / phrase exists in the voice inputted by the word / phrase identifying means after the voice input, the fact (the voice input is clearly performed and the predetermined word / phrase is included in the voice). May be transmitted to the worker using sound, vibration, characters, images, or the like. With such a configuration, when there is no transmission of “clear”, the worker can recognize that it is “unclear”.
