Abstract

The present invention provides a data encoding processing method for speech signals. The data encoding processing method for the speech signals is realized by a speech digital processor, a speech data transmission system, a microprocessor, software, a time delay unit and a data transient memory. With the method adopted, the problems of non-uniform delay, inconstant data reception rate or data packet loss in the IP transmission process of speech data can be solved, and fidelity and understandability of speech in the IP transmission process can be improved.

Description

technical field [0001] The invention relates to voice data IP communication transmission technology, and belongs to the technical field of voice communication. Background technique [0002] In the current voice data IP communication transmission technology, the voice signal is sampled and digitally processed at the voice sending end, then encoded, transmitted to the receiving end for decoding according to the IP transmission protocol, and then the voice data signal is restored to a voice analog signal The transmission processing process; because the voice signal is a continuous real-time process signal, and in the IP transmission process, there are phenomena such as uneven delay of data packets, inconstant data reception rate or data packet loss during the transmission process, which may cause The fidelity and intelligibility of voice data in IP transmission may decrease, so it is necessary to do some improvement work on IP voice transmission technology; the comparative tech...
