河北经贸大学毕业论文

摘要

现代社会人们工作日程繁多紧凑，随着生活节奏的加快，合理的安排时间和遵守时间是每个人的愿望，本文介绍的智能记事器，采用语音播报，随着语音芯片的普及，语音报播被广泛应用于车站报站器，语音型数字万用表，出租车语音报站器，排队机等。可快速直观的给人们提醒工作日程，将成为人们生活中的有力助手。

本文提出了基于AT89C51单片机的语音播报器的设计方案。方案以单片机作为系统的控制核心，详细介绍了ISD公司生产的ISD2560语音芯片的优点及其使用方法。并且给出了用AT89C51与ISD2560构成的语音系统的硬件原图和软件设计方法。采用ISD单片语音录音/放音集成电路系列中的ISD2560实现了语音的存储和播放，使语音音质自然真实。ISD2560不需要A/D和D/A转换，并且集成度高，能实现复杂的信息处理功能，真实的再现语音。实现了当按下开始键，启动录音，松开开始键，结束录音。结束录音后，循环播放所录音的基本功能。并且录放系统具有电路简明、应用方便、单片录放、不怕掉电、音色纯正、性价比高等特性。
