摘要
阐述了利用话音插空技术实现话音和数据同时传输的原理,对话音技术中话音与数据的自动识别进行了探讨,设计出准确性和实时性都较好的话音检测器。介绍了一种行之有效的SSDT/TASI(话音数据同时传输/话音插空)系统。
The principle of utiliging speech interpolation technique to implement simultaneous transmission of voice and data is elaborated. In view of studying the automatic discumination between voice and data in voice technigue, a voice detector design is brought off with fairly well accuracy and real time performance. An effective SSDT/TASI system is untroduced finally.
