Abstract

The invention discloses a method and system for a conversation between a simplex terminal and a duplex terminal. The method comprises the steps: S1, receiving a calling signal and establishing a conversation connection according to the calling signal; S2, receiving a voice signal and performing digital analysis process on the voice signal to judge whether the voice signal is a human voice signal or not, and if so, executing the step S3; and S3, generating an effective human voice indicator signal, and setting a simplex transceiving unit to be in a transmitting state according to the effective human voice indicator signal, and transmitting the voice signal to the simplex terminal. The invention has the advantages of high human voice identification accuracy, no voice loss, stability and reliability; the interferences of non-human voice signals are fully removed; and the aim for smooth conversations between mobile phones or wired landline telephones and interphones is realized.
