摘　　要：分析了语音芯片内部地址的形成机制及特征,介绍了获取芯片内部语音信息段地址的方法,通过采用子片与母片相同地址同步录放的方式开发设计了语音芯片批量拷贝系统。由于一次性语音多片拷贝,减轻了录音中重复操作的繁琐;给出了软件设计和硬件设计,并通过测试验证了系统的可行性,具有一定的应用价值。The formation mechanism and features of the speech chips＇ internal address are analyzed, and how to achieve the internal voice segments address of chips is explained. Since the son slice and master slice adopt the way of same address and synchronous recording, the batch copy system of speech chip is therefore designed and developed. Due to one-time voice more pieces of copy, the repetitive operation in recording is avoided. The software design as well as the hardware is given, and the feasibility of the system is verified.
