从语音电子钟的设计原理、设计方案入手，详细介绍了系统硬件设计、软件设计及调试。在语音电子钟的设计中，要处理好以下几个关键：D/A（数/模）转换，语音识别，人机接口，程序设计。D/A（数/模）和语音识别技术关系到时间的正确播报，人机接口是播报时间和调整时间的关键。利用凌阳SPCE061A单片机在语音识别和处理方面的优点，结合实践，设计出有特色的语音电子钟。-Voice clock from the design principles of design, a detailed descr iption of the system hardware design, software design and debugging. In the design of voice clock, handle the following key: D/A (D/A) conversion, speech recognition, human-computer interface, programming. D/A (D/A) and voice recognition technology related to the correct broadcast time, broadcast time and man-machine interface is the key to adjust the time. Sunplus SPCE061A SCM use in speech recognition and processing advantages, combined with practice, design distinctive voice clock.
