| 中文摘要: |
| 语音识别中语音信号端点检测的准确度起着至关重要的作用，传统的频带方差算法在强背景噪声环境下性能下降。提出一种改进算法，在保证算法复杂度较低的条件下，大大提高了检测的准确度。仿真证明，该算法在低信噪比条件下也具有较强的鲁棒性。 |
| 英文摘要: |
| The accuracy of speech recognition in speech signal endpoint detection plays an important role. Traditional frequency band variance algorithm gives a bad performance in strong noise environment. In ensuring a lower computational complexity conditions, Put forward an improved algorithm, which can greatly improve the accuracy of detection. The simulation results show that the algorithm has strong robustness under low SNR condition. |
