Abstract
The utility model discloses a kind of Voice command dictation device.This device comprises microphone, voice recognition unit, CPU (central processing unit), audio playing unit, dictation content storage unit and loudspeaker.Voice recognition unit, audio playing unit and dictation content storage unit are connected with CPU (central processing unit) respectively by data bus, microphone connects the collection that voice recognition unit is used for user voice command, and loudspeaker connects audio playing unit for dictating the broadcasting of contextual audio file.In the utility model embodiment, this device can identify user voice command and play corresponding dictation contextual audio file, exempts user's manual operation button and switches dictation content, thus is more absorbed in and writes and improve dictation efficiency.
Description
Technical field
The utility model relates to electronic learning product field, is specifically related to a kind of Voice command dictation device.
Background technology
Chinese language new word and foreign language word dictation are one of modal homework of students in middle and primary schools, have no time for avoiding the head of a family and to enter for child or enter for inaccurate and delay child's study, market has much based on the dictation machine of audio-frequence player device, can replace manually reporting dictation content.
But these dictation machines are in report process, need operation push-button to realize the switching of different new word or word, student often writes a new word or word, all needs operation one-touch to select next new word or word, so not only loaded down with trivial details but also affect the writing process of student.
Summary of the invention
The purpose of this utility model is to provide a kind of dictation device with speech identifying function, and user can control to play dictation content by voice command.
The utility model Voice command dictation device, comprises microphone, voice recognition unit, audio playing unit, dictation content storage unit, CPU (central processing unit) and loudspeaker.
Described voice recognition unit, audio playing unit are connected with CPU (central processing unit) respectively by data bus with dictation content storage unit.
Described microphone connects the collection that voice recognition unit is used for user voice command.
Described voice recognition unit is for identifying the voice command of user;
Described audio playing unit is used for decoding and the sound signal power amplification of audio file;
Described loudspeaker connects the broadcasting that audio playing unit is used for audio file.
Described dictation content storage unit is used for depositing dictation contextual audio file;
Described CPU (central processing unit), according to voice recognition unit user voice command recognition result, is extracted corresponding audio file from dictation content storage unit and is sent to audio playing unit.
The beneficial effects of the utility model, user controls the broadcasting of dictation content by voice command, thus has liberated both hands, and student is absorbed in writing of new word or word more.
Accompanying drawing explanation
Fig. 1 is that one of the present utility model preferably realizes structured flowchart.
Fig. 2 is dictation workflow diagram.
Embodiment
Below in conjunction with accompanying drawing, concrete introduction is done to the utility model.
Fig. 1 is that one of the present utility model preferably realizes structured flowchart, comprising microphone 101, loudspeaker 105, voice recognition unit 102, CPU (central processing unit) 103, audio playing unit 104 and dictation content storage unit 106.
Described storage unit 106 is preferably SD card, and for storing the audio file of Chinese language new word and foreign language word pronunciation, each new word or pronunciation of words are an independent mp3 audio file.
Described microphone 101 is preferably miaow head, for gathering the voice command that user sends.
Described voice recognition unit 102 selects the SR170X signer-independent sign language recognition module of Shenzhen Sheng Xi company, by preset identification entry " next one ", voice commands such as " repetitions ", when user sends these voice commands, voice recognition unit will obtain corresponding recognition result.
Described audio playing unit 104 selects VS1003MP3 decoding chip and the digital audio-power amplifier chip PAM8403 of VLSI company of Finland, amplifies for the decoding and sound signal of dictating contextual audio file.
Described CPU (central processing unit) 103 selects the STM32F0 series monolithic of STMicw Electronics, and CPU (central processing unit) 103 is connected with storage unit 106 and audio playing unit 104 by spi bus, and is connected with voice recognition unit 102 by I2C bus.
Dictate workflow diagram as shown in Figure 2, Chinese language new word dictation process and process illustrate as follows:
After dictation device enters dictation state, CPU (central processing unit) 103 reads first new word audio file and delivers to the pronunciation that audio playing unit 104 plays this new word from dictation content storage unit 106.
Enter halted state after finishing playing and start speech identifying function.
After user writing completes, control the pronunciation of next Chinese language new word by " next one " voice command and play, or by " repetition " voice command, again listen to the pronunciation of current Chinese language new word and play.
During speech recognition, any response is not done for invalid voice command system.
Circulation like this is until listen and write all Chinese language new words.
This implementation column has only carried out setting forth just understanding method of the present utility model and core concept for helping to principle of the present utility model and embodiment, simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the content of this instructions all will change in specific embodiments and applications, so should not be construed as to restriction of the present utility model.
