The microphone 3 detects a voice that a diver crawls while holding the mouthpiece 1, converts the detected voice into an electric signal, and outputs the electric signal to the amplifying / shaping device 4.

  The amplifying / shaping device 4 receives an electrical signal from the microphone 3, amplifies the received electrical signal, shapes it, and outputs it to the removal filter 5.

  The removal film 5 removes a component caused by bubbles and a component caused by respiration of a diver from the electric signal received from the amplifying / shaping device 4. Then, the removal filter 5 outputs an electrical signal from which components caused by bubbles and components caused by diving breathing are removed to the A / D converter 6. The removal filter 5 may remove only one of the component caused by bubbles and the component caused by the breathing of the diving person.

  The A / D converter 6 converts the electrical signal received from the removal filter 5 from an analog signal to a digital signal, and outputs the converted digital signal to the compensation circuit 7.

  The compensation circuit 7 recognizes each word based on the digital signal received from the A / D converter 6. Then, the compensation circuit 7 determines whether or not the recognized word is a correct word.

  When determining that the recognized word is not a correct word, the compensation circuit 7 extracts a candidate word that is a correct word candidate by a method that will be described later, and outputs the extracted candidate word to the speaker 2. When the compensation circuit 7 receives the signal COR indicating that the candidate word output to the speaker 2 is a correct word from the operation button 11, the compensation circuit 7 outputs a digital signal indicating the candidate word last output to the speaker 2 to the modem 8. To do.

  The modem 8 converts the digital signal received from the compensation circuit 7 into a transmission signal, and transmits the converted transmission signal via the transmission antenna 9.

  When the operation button 11 receives a signal indicating that the diver has recognized that the candidate word output to the speaker 2 is a correct word, the operation button 11 generates a signal COR and outputs the signal COR to the compensation circuit 7.

  FIG. 2 is a configuration diagram of the compensation circuit 7 shown in FIG. Referring to FIG. 2, compensation circuit 7 includes a buffer memory 71, a word conversion unit 72, and a determination unit 73.

  The buffer memory 71 receives a digital signal from the A / D converter 6 and temporarily holds the received digital signal. The buffer memory 71 holds the digital signal for a certain period of time, and then outputs the held digital signal to the word conversion unit 72.

  The word conversion unit 72 has a built-in electronic dictionary 721. The word conversion unit 72 recognizes a word based on the digital signal received from the buffer memory 71. Then, the word conversion unit 72 outputs the recognized word to the determination unit 73.

  When the word conversion unit 72 receives a signal ICOR indicating that the word is incorrect from the determination unit 73, the word conversion unit 72 extracts candidate words for converting the recognized word into a correct word using the electronic dictionary 721. Then, the word conversion unit 72 outputs the extracted candidate word to the determination unit 73. Details of the electronic dictionary 721 will be described later.

  When the determination unit 73 receives a word from the word conversion unit 72, the determination unit 73 outputs the received word to the speaker 2. Then, the determination unit 73 determines whether or not the word received from the word conversion unit 72 is correct by determining whether or not the signal COR is received from the operation button 11.

  When the determination unit 73 determines that the word received from the word conversion unit 72 is not correct, the determination unit 73 generates a signal ICOR and outputs the signal ICOR to the word conversion unit 72.

  On the other hand, when the determination unit 73 determines that the word received from the word conversion unit 72 is correct, the determination unit 73 outputs the digital signal of the candidate word that was last output to the speaker 2 to the model 8.

  FIG. 3 is a diagram showing a specific example of the electronic dictionary 721 shown in FIG. Referring to FIG. 3, electronic dictionary 721 includes an original word and a correct word. The original word is a word detected by the microphone 3 when the microphone 3 has picked up the mouthpiece 1, and the correct word is associated with the original word and is the correct word of the original word. .

  For example, when a diver scolds the mouthpiece 1, “Toumeido” sounds like “Toueido”. When a diver scolds with a mouthpiece, the “mask” sounds like “ask” and the “nami (wave)” sounds like “not”. As described above, when a diver scolds the mouthpiece 1, the word “ma line” is heard by mistake.

  Also, when a diver scolds the mouthpiece 1, “Pun (minute)” sounds like “Yes”, “Palau” sounds like “Arao”, and “Saipan” means “Saian”. Sounds like As described above, when the diver scolds the mouthpiece 1, the word “pa line” is heard in error.

  Furthermore, when the diver scolds with the mouthpiece 1, “Diving” sounds like “Daiingu”, “Diver” sounds like “Daiah”, “Maldives” Sounds like "Iu". Thus, if a diver scolds with the mouthpiece 1 in hand, the word “ba line” will be heard by mistake.

  The mouthpiece has a height in a state where the mouth is half-opened, a width close to the width of the mouth, and a slightly flat cylindrical body. The depth and length of the mouthpiece is up to the teeth, and the rest protrudes from the mouth and is fixed by being bitten by the upper and lower teeth.

  Therefore, since the mouth is always in a half-open state, it is difficult for a diver who added a mouthpiece to utter the sound of pacing, running and turning by opening and closing the lips, for example. It is.

  Therefore, in the embodiment of the present invention, when a diver hits the mouthpiece 1 with respect to the words “ma line”, “pa line”, and “ba line”, which are easy to mistake, the original word and the correct word Is created, and when the words “ma line”, “pa line”, and “ba line” are input, the compensation circuit 7 uses the electronic dictionary 721 to enter “ma line”. "," Pa line "and" ba line "are converted into correct words.

  Accordingly, the electronic dictionary 721 associates the original word with the correct word for the words “ma line”, “pa line”, and “ba line” that are likely to be mistaken when a diver speaks while holding the mouthpiece 1. It is a thing.

  In addition, the first to 18th words in the electronic dictionary 721 are diving terms, the 19th to 28th words are place names, and the 29th to 60th words are organisms that inhabit the sea. Is the name. Therefore, the electronic dictionary 721 associates the original word and the correct word with respect to the word necessary for the diving work. That is, the electronic dictionary 721 associates the original word and the correct word with respect to the word used for underwater communication.

  FIG. 4 is a diagram illustrating a state in which the communication device 100 illustrated in FIG. 1 is attached to a diver. Referring to FIG. 4, diver DIV carries air cylinder 20 and holds regulator 30 in his mouth. The diver DIV wears a mask 40 and a snorkel 50 and wears a diving computer 50 on the wrist.

  FIG. 5 is a flowchart for explaining the operation of communication apparatus 100 shown in FIG. Referring to FIG. 5, when the operation of communication device 100 is started, microphone 3 detects a voice that a diver crawls while holding mouthpiece 1 (step S <b> 1), and uses the detected voice as an electric signal. It converts into a signal (step S2).

  Then, the microphone 3 outputs the electric signal to the amplifying / shaping device 4, and the amplifying / shaping device 4 amplifies and shapes the electric signal and outputs it to the removal filter 5.

  Based on the electrical signal received from the amplifying / shaping device 4, the removal filter 5 removes the component caused by the bubbles and the component caused by the breathing of the diver (step S <b> 3), and the components caused by the bubbles and the diver. An electrical signal from which components due to respiration are removed is output to the A / D converter 6.

  The A / D converter 6 converts the electrical signal from an analog signal to a digital signal, and outputs the converted digital signal to the compensation circuit 7.

  The buffer memory 71 of the compensation circuit 7 temporarily holds the digital signal received from the A / D converter 6 and outputs the held digital signal to the word conversion unit 72. The word conversion unit 72 recognizes the word based on the digital signal received from the buffer memory 71 (step S4), and outputs the recognized word to the determination unit 73.

  The determination unit 73 outputs the digital signal of the word received from the word conversion unit 72 to the speaker 2, and the speaker 2 converts the digital signal from the determination unit 73 into sound and outputs the sound. The diver listens to the sound output from the speaker 2 and presses the operation button 11 when he / she hears the word he / she intended. On the other hand, the diver listens to the sound output from the speaker 2 and does not press the operation button 11 unless the intended word is heard.

  When the operation button 11 is pressed by a diver, the signal COR is generated and output to the determination unit 73 of the compensation circuit 7. When the operation button 11 is not pressed by the diver, no signal is output to the determination unit 73 of the compensation circuit 7.

  Therefore, the determination unit 73 determines that the word received from the word conversion unit 72 is correct when receiving the signal COR from the operation button 11 after outputting the digital signal of the word received from the word conversion unit 72 to the speaker 2. .

  On the other hand, when the determination unit 73 does not receive the signal COR from the operation button 11 after outputting the digital signal of the word received from the word conversion unit 72 to the speaker 2, the word received from the word conversion unit 72 is incorrect. judge. In this case, after the determination unit 73 outputs the digital signal of the word received from the word conversion unit 72 to the speaker 2, for example, when the signal COR is not received from the operation button 11 even after one second has elapsed, the word conversion unit It is determined that the word received from 72 is incorrect.

  As described above, when the determination unit 73 receives the word from the word conversion unit 72, the determination unit 73 determines whether or not the word received from the word conversion unit 72 is correct by determining whether or not the signal COR is received from the operation button 11. Determine (step S5).

  In step S <b> 5, when it is determined that the word received from the word conversion unit 72 is not correct, the determination unit 73 generates a signal ICOR and outputs it to the word conversion unit 72.

  In response to the signal ICOR, the word conversion unit 72 uses the electronic dictionary 721 to extract correct word candidate words (step S6), and outputs the extracted candidate words to the determination unit 73.

  The determination unit 73 presents the candidate word received from the word conversion unit 72 to the diver through the speaker 2 (step S7).

  Thereafter, the series of operations returns to step S5, and the above-described steps S5 to S7 are repeatedly executed until it is determined in step S5 that the word is correct.

  If it is determined in step S5 that the word is correct, the determination unit 73 outputs the candidate word finally output to the speaker 2 to the modem 8, and the model 8 transmits the word received from the determination unit 73. The signal is converted into a signal, and the converted transmission signal is transmitted via the transmission antenna 9 (step S8).

  As a result, the operation in the communication apparatus 100 ends.

  As described above, in the communication device 100, the compensation circuit 7 converts an easy-to-error word into a correct word using the electronic dictionary 721 and transmits it when the diver crawls with the mouthpiece 1 in hand. The electronic dictionary 721 associates and retains an original word that is an error-prone word when a diver scolds the mouthpiece 1 and a correct word that is a correct word corresponding to the original word. ing.

  Therefore, it is possible to convert a word spoken by a diver while holding the mouthpiece 1 into a correct word and transmit it.

  The diver wears the communication device 100 on a diving tool as shown in FIG. 4 and dives, and uses the communication device 100 to utter a correct word while holding the mouthpiece 1. As a result, divers can smoothly communicate with other divers in the sea.
