摘要
针对车载免提系统中的话音质量和传输速率问题,利用蓝牙模块近距离的高速传输特性,采用语音合成模块和回音抑制芯片,借助MultiSim及PADS2005硬件设计工具,完成了硬件电路设计和调试.测试结果表明:系统在稳定性、安全性和低能耗方面都有所提高.
The hands-free system needs clear voice and rapid transmission, using the Bluetooth module, the TTS Module and the integrated hands-free car kit IC that improves voice quality and noise suppression. Using PADS2005 and MultiSim for hardware design complete hardware circuit design and debug. The test results prove that the stability, security and energy aspects have been improved.
