| 摘 要： | 主要研究了利用四阶累积量在房间环境下的语音信号时延估计。根据模拟实验环境和实际实验环境下的仿真结果,分别比较了在高斯白噪声情况下与有色高斯噪声情况下基于二阶统计量的广义互相关法和基于四阶累积量的时延估计法性能,验证了四阶累积量法的有效性。仿真结果表明四阶累积量法具有很好的鲁棒性。

| Abstract: | A speech signal time delay estimation method based on fourth-order cumulants in room is described in detail. The validity of the fourth-order cumulants algorithm is assessed by experiments with Gaussian noise and pink noise in simulated reverberant room and in real world. Furthermore, compared with the cross cumulants method, the results shows that the fourth-order cumulants approach is superior and robust. |
