Vehicle Embedded Speech Recognition and Control System Research and Implementation

For the driver in the process of moving inconvenient to manually operated vehicle electronics, as well as the monopoly of foreign technology and other issues related, a framework based on DSP + MCU car speech recognition, and control systems is designed. According to the embedded application environment, the corresponding recognition algorithm and the hardware architecture of DSP + MCU are chosen, in which DSP is mainly responsible for voice signal processing work, MCU is responsible for communicating with DSP and MCU to obtain recognition results after speech signal processing, as the final control instructions.The experimental results show that the hardware platform can run normally, and control the car body light on experimental bench.
