我们提出了一种新的语音活动电平估计方法,该方法将基于有声语音能量提取的新颖算法与标准化 ITU-T 建议 P.56 相结合。在信噪比较差的情况下,该算法通过识别有声语音的间隔并对时频域中音调谐波的能量求和来估计活动电平,同时抑制噪声的能量。我们将我们的方法的性能与 TIMIT 数据库上的 ITU-T P.56 的性能进行比较,并证明该方法在高水平和低水平的加性噪声​​中都表现得非常好。
We present a new method for speech active level estimation which combines a novel algorithm based on voiced speech energy extraction with the standardized ITU-T Recommendation P.56. At poor signal-to-noise ratios, the algorithm estimates the active level by identifying intervals of voiced speech and summing the energy of the pitch harmonics in the time-frequency domain while rejecting that of the noise. We compare the performance of our method with that of ITU-T P.56 on the TIMIT database and demonstrate that it performs exceptionally well in both high and low levels of additive noise.
