[摘要]：
 凌陽十六位單片機具有獨特強大的可編程數字語音信號處理識別功能及DSP運算功能，本系統即利用其強大的語音功能對撥入電話進行語音報號及錄音放音。系統以凌陽SPCE061A十六位單片機作為主控MCU，配合1420錄音芯片、ＬＣＤ顯示模塊、鍵盤模塊、DTMF編譯碼等完成對撥入電話的來電信息進行DTMF/FSK解碼顯示、語音報號、振鈴信號的檢測及計數、提示音播放、錄音放音及掛機檢測、錄音信息顯示等。該系統兼有錄音機及復讀機功能，設有錄音、放音、停止三個手動按鍵，可隨時錄入自己所需的信息。錄音芯片采用ISD1420，可以高質量、自然的語音還原，自動節電，不耗電信息保存100年，十萬次錄音周期。因此可以反復的播放存儲。加上凌陽單片機內嵌32Ｋ的FLASH閃存，系統總的錄音時間近二十五分鐘，可對錄音信息進行分頁多條錄入。該系統操作簡單、方便實用、科技含量高！

According to 16 intelligences of MCU of SunPlus recording telephone
[Summary]:
 16 MCU tools of Sunplus contain the special and strong programmable numerical speech  signal processing identify the function and the DSP operation functions, this system makes use of its strong speech function to carry on the speech report number and the recording playbacks towards stiring into the telephone namely.The system is the lord to control the MCU with the SPCE061A 16 MCU of the Sunplus, matching with 1420  recording chips, the ＬＣＤ manifestation mold piece, keyboard mold piece, DTMF to edit and translate the code etc. complete to stir telephone into the telephone the information carries on the DTMF/ FSK decoding manifestation, speech  report number and flaps the bell signal of examination and count, hint the sound to broadcast, record sound the playback and hang the machine examination and record sound information manifestation etc..That system and have the tape recorder and reply to read the machine function, establish the recording, playback, stop three handses move the key, can at any time record into oneself need of information.Record sound the chip adoption ISD1420, can restore with the speech of the high quantity, nature, the automatic stanza electricity, don't consume the telecommunication interest to keep 100 years, record sound the period 100,000 times.Therefore can broadcast again and again saving.The FLASH RAM that pluses 32 Ｋ of inside the MCU of Sunplus save, total recording time of system can reach to be close to 25 minutes, can carry on dividing manies of page to record to go into to the recording information.That system operation is simple, the convenience is practical, science and technology content is high!
