【摘要】 说话人自适应是提高非特定人语音识别性能的有效方法之一。本文将MAP算法应用于汉语数码语音识别中，并讨论了几种加快自适应速度的方法以及自适应对非自适应人的影响。实验表明，MAP算法可以有效地降低汉语数码语音识别对被适应人的误识率，而且对非自适应人性能影响很小。更多还原

【Abstract】 Speaker adaptation is one of the effective approaches to improve the performance of speaker-independent speech recognition. This paper applies the MAP algorithm to the Mandarin digital speech recognition, and discusses several approaches that accelerate the adaptation process as well as the effects on the non-adapted speakers. The experiment shows that the MAP algorithm can considerably reduce the error rate of Mandarin digital speech recognition on the adapted speaker and cause little influence on the non-adapted speakers.更多还原
