| 摘 要： | 根据语音的发声特点,基于分析语音信号中的基音频率和语音之间的关系,提出一种在强噪声环境下实现提高语音识别率的方法,并对基于基音频能值的端点检测算法和传统语音端点检测算法进行比较.实验结果表明该方法不仅能够有效提高语音段的检测率,同时还具有计算量小、实时性高、不受噪声影响即鲁棒性好等特点.

| Abstract: | According to the audio features, this paper ananlyses the relations between pitch and speech. On this basis, a method of improving speech recognition accuracy in the presence of strong noise is proposed. And in comparison with traditional Endpointing Algorithms, this method not only effectively improves speech recognition accuracy,but also is of small amount of computing, better real-time performance,strong robustness and so on. |
