摘要
介绍了ISD2500系列语音芯片工作原理及其在报警系统中的应用,同时给出了语音段落组合播放方法和语音复制电路的设计;由于ISD系列语音芯片是采用模拟方式来存储语音信息,因而语音信息的复制较为困难;针对此问题,给出了在语音段落起始地址已知和未知的情况下,运用连续寻址模式来实现语音信息复制的方法;经实践证明该方法简便可靠,达到了较为理想的复制效果。
The principle of ISD series voice devices was introduced, and an application in alarm system is realized, with a method combining voice segments when playing and a way to design the voice duplication circuit is proposed. To solve the problem of difficult voice message duplication caused by the unique analog mode message storage in tSD, the paper developed a method of voice duplication with the consecutive addressing mode. The versatility of the method whether the start addresses of voice information were accessible or not was researched and the factual voice duplication circuit was realized. With the efficient results in factual application, the method was proved to be an simple and dependable way of voice duplication.
