摘要： 不同的汉语语音关键词识别系统,以关键词为单位建立模板工作量大而且可重用性较差,而以音节为单位可以很好地提高重用性。将弹性音节拼接与具有较高性能的基于特征空间轨迹匹配的关键词检测相结合构建识别系统,实验结果表明该系统具有相当高的识别率。

Abstract: To establish template for each keyword is laborious and the template isn’t reusable,but choosing syllable as subword can solve the problem.This paper proposes a keyword spotting method based on adjustable syllable joining and feature space trace matching,experiments show that this method has high performance and efficiency.
