摘 要钟是现代人类日常生活必不可少的工具，语音时钟更是现在电子时钟多功能化进展的一个方向。语音电子钟具有突出的播报时间的功能，它被广泛用在生活中的各种场合。本设计就是从日常生活中常见的事物入手，通过对语音电子钟的设计，让我认识到单片机已经深化到我们生活的每个领域。本文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。关键字： SPCE061A 单片机 SPLC501 液晶显示器 语音报时AbstractClock is an essential tool for daily life.In morden society develop direction of clock with electronic is having the fuction for broadcasting.It is good to broadcast time. This design dates from common life, from the experience of this design I realize the truth that SCM hasing the depth to each area of our lives. The paper illustrate for the electronic voice clock’s design principles, details of the system hardware, software design and debugging. In this voice design of electronic clock, we must properly handle the following key.Firstly D/A conversion,secondly speech recognition,then human-machine interfaces, lastly program design. D/A conversion and voice recognition technology related to the correct broadcast of time, human-computer interface is the key to broadcast and adjust the time. Therefore, the Sunplus 61A microcontroller has high advantage in speech recognition and processing .Combineing the practice, design a unique voice electronic clock.
