【正文】 摘 要現代社會人們工作日程繁多緊湊，隨著生活節(jié)奏的加快，合理的安排時間和遵守時間是每個人的愿望，本文介紹的智能記事器，采用語音播報，隨著語音芯片的普及，語音報播被廣泛應用于車站報站器，語音型數字萬用表，出租車語音報站器，排隊機等?？煽焖僦庇^的給人們提醒工作日程，將成為人們生活中的有力助手。本文提出了基于 AT89C51 單片機的語音播報器的設計方案。方案以單片機作為系統(tǒng)的控制核心，詳細介紹了 ISD 公司生產的 ISD2560 語音芯片的優(yōu)點及其使用方法。并且給出了用 AT89C51 與 ISD2560 構成的語音系統(tǒng)的硬件原圖和軟件設計方法。采用 ISD 單片語音錄音/放音集成電路系列中的 ISD2560 實現了語音的存儲和播放，使語音音質自然真實。ISD2560 不需要 A/D 和 D/A 轉換，并且集成度高，能實現復雜的信息處理功能，真實的再現語音。實現了當按下開始鍵，啟動錄音，松開開始鍵，結束錄音。結束錄音后，循環(huán)播放所錄音的基本功能。并且錄放系統(tǒng)具有電路簡明、應用方便、單片錄放、不怕掉電、音色純正、性價比高等特性。關鍵詞 電氣信息；單片機；語音芯片；ISD2560AbstractModern social pact many people work schedule, with the pace of life speeds up, reasonable arrangements to ply with the time and the time is everyone39。s paper introduces the intelligent accounts regulator, with speech broadcast, with the popularization of pronunciation chip, voice newspaper has been widely used in the station broadcast stops device, voice type digital multimeter, taxi voice stops PaiDuiJi ware, etc. The paper introduced a smart notepad, a voice broadcast, fast intuitive to remind people work schedule, people living in a strong assistant.In this paper a design program of voice broadcast device based on AT89C51 microcontroller is introduced in this paper. Singlechip microputer is the core of control paper introduces the PIN function,operating model and using method of ISD2560 voice forword the hard structure and soft design method of the voice system consisted of AT89C51 and ISD2560. The use of singlechip voice recording ISD / playback IC ISD2560 series achieve voice storage and playback, and the voice is true ,natural ,quality. We achieve the basic function that when the start button is pressed , the device start to record and when the start button is releasd ,the device finish recording. Then broadcast what it record loop three times. And recording system has circuit concise and easy application, monolithic recording, not afraid off electricity, tone, pure, high performancetoprice characteristics.
