藏语拉萨语LPC语音参数提取研究
Research on speech parameter extraction of LPC in Tibetan Lhasa language
摘要
Abstract
Tibetan speech parameter extraction is the one of the key technologies of Tibetan speech recognition. The accura-cy of parameter extraction directly affects the effect of speech recognition. Linear prediction coefficient(LPC),as an important frequency domain parameter of speech signals,is currently an important processing technology in speech signal processing and widely used in the process of speech compression,speech acoustic modeling,speech synthesis,speech recognition and so on. In this paper,the principle of linear prediction algorithm is introduced. A scheme of LPC parameter extraction from Tibetan speech signals is proposed. LPC parameter extraction from Tibetan speech signals and simulation analysis are conducted on the Matlab platform. The results of the research provide some references for improving the Tibetan speech synthesis technology and the efficiency of speech recognition.关键词
