Abstract

The invention discloses a method and a device for decoding voice data. The method comprises the following steps: receiving a voice data packet to be decoded, wherein the voice data packet contains one to a plurality of voice frames; obtaining the cutting parameter of a current searching network corresponding to a corresponding voice frame; regulating the cutting parameter of the searching network according to the decoding time delay of the corresponding voice frame; decoding the corresponding voice frame by Viterbi searching in the searching network after the corresponding cutting parameter is regulated; or, receiving the voice data packet to be decoded, wherein the voice data packet contains one to a plurality of voice frames; obtaining the cutting parameter of the current searching network corresponding to the corresponding voice frame; decoding the corresponding voice frame by Viterbi searching corresponding to the cutting parameter of the current searching network; and regulating the cutting parameter of the searching network according to the decoding time delay of the corresponding voice frame. By the method and the device for decoding the voice data, the controllability of the decoding time delay is realized by the self-adapting regulation of a searching and cutting threshold, and the practical value of a system is enhanced.

Description

technical field [0001] The present invention relates to the technical field of recognition processing, and more specifically, to a voice data decoding method and device. Background technique [0002] It has become an urgent need for the current application and development of information technology to realize the humanized and intelligent effective interaction between man and machine, and to build an efficient and natural man-machine communication environment. In recent years, online speech recognition applications such as sending microblogs and writing text messages in the field of mobile communications have received more and more attention. In this instant messaging mode, users have higher requirements for system response speed, and always hope to get feedback results without obvious delay after the voice input ends. The real-time performance of a speech recognition system has become one of the most important indicators for measuring system performance. The shorter the sys...
