As advanced optimizing for Fig. 3 corresponding embodiment, can by target time section bone vibration data with
Voice data executes following steps when being sent to speech recognition module:
The delay duration of the initial time of step 1, the Startup time for calculating phonetic incepting component and voice data；
Delay duration is sent to speech recognition module by step 2, so that speech recognition module is executing speech recognition operation
Intercept operation is executed to the bone vibration data in target time section before and obtains the bone that there is identical initial time with voice data
Vibration data.
Above-mentioned optimization is there are problems that delay phonetic incepting component acquisition voice data, because in processing chip
Deterministic process needs certain time, then can also have delay to phonetic incepting component electrifying startup, and phonetic incepting component powers on
Arrive afterwards can steady operation equally exist delay.Therefore it should be noted that postponing bone vibration data caused by duration and voice data not
The problem of alignment, such as when wearer says " playing music ", bone vibration data is exactly complete Pinyin are as follows: bo fang
Yin yue, and voice data may are as follows: o fang yin yue needs to intercept data after buffered data, that is, needs
Guarantee that two data are all o fang yin yue.
The treatment process that the above process is illustrated because of the speech detection algorithms in the DSP of processing chip needs 5.5ms,
Then to phonetic incepting component electrifying startup there are the delay of 2.5ms, phonetic incepting component arrives after powering on is capable of steady operation
Delay is 30ms, so phonetic incepting module data will about postpone bone vibration data 38ms.So in use, to infuse
The problem of meaning delay is misaligned, such as when wearer says that bone vibration data is exactly complete Pinyin are as follows: bo when playing music
Fang yin yue, and voice data may be exactly that there are voice data are as follows: o fang yin yue is needed after buffered data
Data are intercepted, that is, need to guarantee that two data are all o fang yin yue.The baud rate of phonetic incepting component is
16Kbps, interception formula areLen be bone vibration data need to intercept by starting point of start time when
It is long.
The difference of a length of bone vibration data and voice data initial time when delay mentioned above sends delay duration
To speech recognition module, so that speech recognition module intercepts bone vibration data according to delay duration, to identical initial time
Bone vibration data and voice data carry out speech recognition operation.
As an alternative embodiment, carrying out speech recognition operation related data is sent to speech recognition module
Later, there may also be following operations: when receiving the recognition failures information of speech recognition module transmission, control audio is played
Component plays voice data, so that wearer checks voice data.
Defaulted herein when speech recognition module can not identify the data received or obtained recognition result is wrong, voice
Identification module returns to recognition failures information to the processing chip of intelligent wearable device.When processing chip receives recognition failures information
The voice data that control audio player module records before playing afterwards determines language so that wearer listens to speech content just now
The reason of sound recognition failures, allows wearer to adjust the speech content of oneself to carry out the mistake of voice collecting and speech recognition again
Journey.
Further, any one of the above embodiment description intelligent wearable device phonetic incepting component can for
The phonetic incepting component of decrease of noise functions can execute echo cancellation and/or noise reduction trim process to the voice data received.
For example, phonetic incepting component can built-in 2 microphones, at the bis- mic noise reduction algorithms progress noise reductions of alango
Reason, a microphone, which is stablized, keeps clear call, another microphone physics actively eliminates noise, by collecting extraneous sound
After being handled, the sound wave opposite with noise is issued, eliminates noise using principle of cancellation, is conducive to improve speech recognition below
Discrimination.
