Influence of Acoustics in Speech Recognition for Oriental Languages
Abstract
As agileTV, Nuance XML Platforms, Microsoft Speech server2004 are the projects in the news, there is still a demand for a better speech recognition engine in terms of WER. This article puts forward the acoustic signal quality requirement for efficient speech recognition. It reports that the major thrust is on the acoustics of speech recognition. It also envisages the performance of various speech recognition engines in the industry, the techniques adopted by them towards achieving the quality acoustic signal of the speaker for efficient results [in terms of Less Word Rate Error] and the impact of the external factors that makes it less robust in terms of attaining high quality speech signal. To tackle the problem we suggest an intelligent mechanism of modification in the regular Input speech signal format for significant improvement in speech recognition.
