基于SPCE061A电话录音系统研究.doc

 基于单片机的电话录音系统研究 摘要 单片机在智能电话录音系统的的运用，主要研究凌阳单片机[1]的各个常用功能模块，特别是语音录用模块。结合服务行业管理对在线录音系统的实际需要，利用SPCE061A单片机，设计一个电话录音系统，实现对客户通话过程的实时监控与录音。 本文首先探讨了数字录音系统的概况，并根据现有的技术条件，利用单片机和一些外围器件设计一种适合家庭、(铃流)并等待至系统默认的振铃次数后 ,控制器自动摘机 ,摘机后在语音电路的提示下将主人留言发送给对方,最后录入对方语音,直到检测到对方挂机为止，完成录音电话的功能。 此次设计采用模块化的设计方案。根据系统的功能主要分为这几部分：振铃检测部分；自动摘挂机部分；DTMF信号解码部分；语音控制与语音录放部分。而本设计的主要内容就是围绕这些部分进行芯片的选择，电路的设计以及软件的设计。 关键词：DTMF解码电路；语音芯片ISD4004；智能电话录音系统 Telephone recording system based on SCM research abstracts and recording SCM in the smart use of the telephone recording system, the main research Sunplus microcontrollers used each functional module, in particular, voice recruiting module. Service industry management with online recording system of the actual needs, the use of SPCE061A, a telephone recording system designed to achieve the customer call process, real-time monitoring and recording. First this paper discusses the digital recording system. According to the existing technical conditions and using single chip and some periphery devices, design an intelligent phone recording system which is suitable for indoor occasions such as family office. 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 14004 recording chips, 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..When there is a call, telephone tests telephone line ringing and the contro
