语音信号中字词端点检测方法的两项改进

Improvement on word endpoint detection in phonetic signal processing

为了提高传统字词端点检测方法检测端点的准确性,分析了传统检测方法的不足,针对语音信号直流分量不为零和长音节尾音被误切割等特殊情况,提出了字词端点检测改进措施。经实验,改进措施有较好实用效果。

The deficiency of traditional detection method for word endpoint detection is analyzed. Measures for improvement are put forward for solving the two problems existed, i.e., non-zero DC-component of phonetic signal and fault cut of word endpoint with long syllable. Experimental results show that the improved method is better than classical method in cases to detect the endpoint of words with long syllable.
