基于文音相似度的语音查询系统的设计与开发

Design and Development of Speech Inquire System Based on Text Speech Similarity

随着语音识别研究的深入,提高通用识别引擎的精度变得越来越困难。但对具体的语音识别任务,结合相应的背景,采取相应的措施,有可能达到很理想的识别精度。在已知语音输入为某有限集元素之一的情形,利用文本在发音上的相似度可以大大提高识别的精度。本文首先介绍了文音相似度的概念,然后给出了利用文音相似度设计开发语音查询系统的过程和例子。

It becomes more and more difficult to improve the accuracy of general speech engine.But in some cases we may obtain ideal accuracy using context knowledge,If speech input is one element of a finite set,we can improve the accuracy greatly using similarity of Chinese text strings.In this paper we first describe the definition of text speech similarity,then give procedure and example of design and development of speech inquire system based on text speech similarity.
