The voice signal can be converted into digital information by the computer through the microphone input of the computer (the voice signal can be converted into Chinese characters by hundred-degree voice assistant or signal flight voice recognition and then converted into numbers) and then sent to the code sender, and the code sender converts the numbers into Moss codes to be sent out (the numbers are converted into the Moss codes by the conventional technology and are converted according to the conventional comparison table of the numbers and the Moss codes). The Chinese characters can also be input through a computer keyboard, and the computer converts the Chinese characters into digital information and sends the digital information to a code sender.
The computer of the code receiving output part can convert the received digital code into Chinese characters and voices (hundred-degree voice assistant or signal flight voice recognition), and the Chinese characters and voices are displayed on a computer display and output through a sound system.
The molar code receiving and transmitting system adopts a parallel mode to beat and transmit telegraph codes (five paths of audio receiving and transmitting channels in fig. 5), namely, one telegraph code is beaten and transmitted at a time. The traditional morse code clapping mode is a serial mode and requires clapping code elements one by one. For example, the telegraph code of the Arabic numeral "3" is composed of 5 elements of "dot", "scratch" and "scratch", and the serial clapping mode is adopted, so that clapping of the telegraph code of the numeral "3" can be completed only by five times. And the number 3 is beaten in a parallel mode, 5 elements are beaten at one time, and the beaten of the number 3 can be completed at one time. Compared with the serial mode, the parallel mode has the greatest advantages of short time consumption and capability of improving the sending speed by at least 8 times.
The molar code receiving and transmitting system has good confidentiality. The parallel beat code is used, when the wireless communication mode is adopted, 5 different frequencies are used, and when the wired communication mode is adopted, 5 audio relay circuits (bandwidth 64K) are used. If a serial clapping mode is adopted, the clapping process of telegram codes can be mastered on 1 frequency (or 1 audio relay circuit). The parallel clapping mode is adopted, and the clapping process of telegram codes can be mastered only on 5 frequencies (or 5 audio relay circuits) at the same time.
The code receiving and outputting system can automatically convert the received Mohs code into voice (through a voice synthesizer) and can automatically convert the received Mohs code into Chinese characters.
The output port of the code sender is connected with the input port (K line interface end or wired audio circuit interface) of the wireless transmitter.
The encoder includes a first output port, a second output port, a third output port, a fourth output port, and a fifth output port.
The first path of output port outputs the 1 st bit element of the telegram code, the second path of output port outputs the 2 nd bit element of the telegram code, the third path of output port outputs the 3 rd bit element of the telegram code, the fourth path of output port outputs the 4 th bit element of the telegram code, and the fifth path of output port outputs the 5 th bit element of the telegram code. When the molar telegraph is less than 5 bits, there are several outputs for several bits. For example, the morse telegraph code arabic number "2" is a "dot" and a "dash", i.e., there are 2 elements, and at this time, the encoder outputs "dot" on the 1 st path, outputs "dash" on the 2 nd path, and no output on the 3 rd path to 5 th path.
The code sender adopts a parallel output mode to finish the Morse code sending. In wireless communication, 5 transceivers are required, one frequency for each transmitter.

The voice conversion part of the invention changes single-path speech recognition into multi-path probability speech recognition.
The voice conversion part of the invention divides 1 path of user voice into 5 paths of voice (the audio signal distribution part divides 1 path of user voice into 5 paths of voice), compares and judges the 5 paths of voice respectively, and takes the voice with highest probability of the same as the correct voice. By adopting the voice recognition mode, the voice recognition probability can be further improved, and the recognition accuracy can reach 90% -100%. When the comparison probability of the compared Chinese characters is 100%, it indicates that the 5 Chinese character groups are the same, and the translation of the Chinese characters is correct, when the comparison probability of the compared Chinese characters is 80%, it indicates that the 4 Chinese character groups are the same, and the translations of the 1 Chinese character group are different, and then the translation of the Chinese character groups with high probability is correct (the voice-to-Chinese character, chinese character-to-voice software can adopt hundred degree voice assistant or signal-to-fly voice recognition). Details are given in the following table.
As can be seen from the table, 7 cases are distinguished in the large-probability correct Chinese character set, when the probability of distinguishing the Chinese character set is 100%, the system outputs the correct Chinese character set with 100% probability, when the probability of distinguishing the Chinese character set is 80%, the system outputs the correct Chinese character set with 80% probability, when the probability of distinguishing the Chinese character set is 60%, the system outputs the correct Chinese character set with 60% probability, when the probabilities of distinguishing the Chinese character set are 40%, 20% and 20% respectively, the system outputs the correct Chinese character set with 40% probability, when the probabilities of distinguishing the Chinese character set are 40%, 40% and 20% respectively, the system cannot judge the correct Chinese character set, so the correct Chinese character set is not output, and when the probabilities of distinguishing the Chinese character set are 20%, 20% and 20% respectively, the system cannot judge the correct Chinese character set, so the correct Chinese character set is not output.
The voice conversion part of the invention has high probability of correctly identifying Chinese character groups.
A single-path speech translation system needs to be trained by a user for a long time to achieve a certain degree of correct translation. If a new speech translation program is started, the correct recognition rate can reach about 60%. After a period of training or longer training of the user, the correct recognition of the speech translation program is improved continuously, but the maximum recognition can reach about 90%. Once translated, the error cannot be recovered. According to the invention, 5 paths of translation are adopted, on the basis that the accuracy rate of the 5 paths of translation is 90%, the 5 paths of voice translation is subjected to large-probability statistics, and the accuracy recognition rate is definitely higher than that of a single path and can reach 90% -100% at most.
The voice conversion part of the invention has high reliability.
Because the speech recognizer designed by the invention adopts 5 paths of speech translations, the speech translation of a certain path only accounts for 20% of the speech recognizer, that is, when the speech translation of a certain path deviates, the whole speech translation of the speech recognizer of the invention is not affected. If the probability of the correct Chinese character set is 60%, the invention allows one or two paths to have translation deviation.

Each microprocessor converts 5 audio signals into 5 Chinese character sets (using hundred degree voice assistant or signal flight voice recognition software), the Cortex-A53 chip M6 in FIG. 11 can judge 5 Chinese character sets (as shown in the above table), and can confirm that the Chinese character sets with the probabilities of 100%, 80% and 60% are correct, when the probabilities of other 3 sets are all 20%, 40% can confirm that the Chinese character sets are correct, when the probabilities of 2 Chinese character sets are 40%, which set is correct cannot be identified, so that the output Chinese character sets are not confirmed, and when the probabilities of 5 Chinese character sets are all 20%, which set is correct cannot be identified, so that the output Chinese character sets are not confirmed. And M6, after judging the 5-path Chinese character group, outputting the result through a network switch.
The voice conversion part divides 1 path of user voice into multiple paths of voice through the audio signal distribution part, so that each path of voice can be converted into Chinese characters through the voice conversion processing part, the correctness comparison of the voice is convenient, and the accuracy of voice recognition can be improved.
