摘要
论述了各种语音激活检测技术的优缺点,利用语音和背景噪声之间的相关性能差异,结合多门限检测技术,提出一种能够在复杂背景噪声环境下进行实时语音激活检测的算法。基于标准语音数据库的仿真结果表明该算法具有较低的实现复杂度,能够自适应地调整判断门限,有效跟踪背景噪声变化情况。实际产品测试结果验证了该算法的有效性。
Based on a detailed analysis on different methods of voice activity detection, a novel algorithm for real-time voice activity detection in noisy environment is presented using the correlation difference between voice and ambient noise and combining with multi-threshold detection technique. Simulations using standard database indicate that the algorithm has low implementation complexity, high detection accuracy and robustness against noise. The effectiveness is verified by product test.
