Design And Implementation Of The Speech Recognition System Based On Android

The continuous development of microelectronics technology,computer efficiency fast,which speeds up the development of other technologies,especially the development of speech recognition.Speech recognition as a new technology in the 20 th century,is slowly changing people's lives.Speech recognition technology research and exploration,has a broad future market and a wide range of applications.This paper summarizes the problems in the development of on-board speech recognition,including the complexity of the algorithm,the high requirement of the hardware,the simplification of the control function,and so on.Finally,the paper introduces the research of the speech control system.In order to solve the above problems,this paper puts forward the offline speech recognition based on LD3320 chip under ARM + Android architecture and the design scheme of on-line speech recognition based on Baidu voice cloud service,and discusses its application in vehicle platform and control unmanned aerial vehicle Specific control applications.On the whole architecture and function realization of the vehicle,the ARM + Android architecture,the peripheral module and the interface circuit are used to design and realize the on-line and off-line multi-mode speech recognition function based on Baidu voice cloud service and LD3320 professional voice chip.Vehicle information system.And the hardware of the vehicle platform has been improved.The Android system has been developed and transplanted.On this basis,the voice control navigation,Bluetooth phone and music playing function have been realized.Which is used to control the off-line voice Bluetooth phone,online voice control for song playback and navigation software.The system supports self-service upgrade and maintenance of navigation software,breaking the monopoly of traditional vehicle system upgrade.Secondly,in the voice control UAV,the use of Android system under the flat design and implementation of a UAV voice control software.Speech is also based on mobile Internet Baidu voice cloud service online voice recognition,speaking to the collected voice commands sent to the UAV through the WIFI communications ground station,packet data packet-send-unpacking.After data packet decoding,the information analysis,control information to obtain specific,and finally through the ground station to send unmanned aircraft flight commands,so that the implementation of UAV action.The experimental results show that the multi-modal speech recognition and control system has low cost,high efficiency,powerful function and friendly operation.It realizes the release of the operator 's hands and improves the safety of driving operation.
