| Abstract: | 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. |
