[摘要]：
 凌阳十六位单片机具有独特强大的可编程数字语音信号处理识别功能及DSP运算功能，本系统即利用其强大的语音功能对拨入电话进行语音报号及录音放音。系统以凌阳SPCE061A十六位单片机作为主控MCU，配合1420录音芯片、ＬＣＤ显示模块、键盘模块、DTMF编译码等完成对拨入电话的来电信息进行DTMF/FSK解码显示、语音报号、振铃信号的检测及计数、提示音播放、录音放音及挂机检测、录音信息显示等。该系统兼有录音机及复读机功能，设有录音、放音、停止三个手动按键，可随时录入自己所需的信息。录音芯片采用ISD1420，可以高质量、自然的语音还原，自动节电，不耗电信息保存100年，十万次录音周期。因此可以反复的播放存储。加上凌阳单片机内嵌32Ｋ的FLASH闪存，系统总的录音时间近二十五分钟，可对录音信息进行分页多条录入。该系统操作简单、方便实用、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!
