车载语音识别及控制系统的设计与实现

DESIGN AND REALIZATION OF VEHICLE SPEECH RECOGNITION AND CONTROL SYSTEM

针对传统的封闭式手动操作的车载系统,设计了基于Android系统的车载语音识别与控制系统。该车载系统采用ARM架构完成硬件搭建,设计并实现了基于网络和LD3320语音芯片的在线离线多模态语音识别功能,并在此基础上实现了语音控制导航、蓝牙电话及音乐播放功能。该系统支持导航软件应用的自助升级和维护,打破了传统车载系统升级的垄断。实验结果表明,该多模态语音识别与控制车载系统成本低、效率高,功能强大、界面友好操作简便,真正意义上释放了驾驶员的双手,具有广阔的市场前景。

Aimed at the traditional enclosed manual operation of the vehicle system,a car speech recognition and control system based on Android system is designed. The vehicle system uses ARM architecture to complete the hardware structures,the on-line and off-line multi-mode speech recognition based on the network and LD3320 voice chip is designed and implemented. On this basis,voice control navigation,Bluetooth phone and music playing function are realized. The system supports self-service upgrade and maintenance of navigation software,breaking the monopoly of traditional vehicle system upgrade. The experimental results show that the multi-mode speech recognition and control vehicle system has low cost,high efficiency,powerful function,friendly interface and easy operation. It realizes releasing the driver's hands and has broad market prospect.
