- Abstract
- In this paper, we propose a method to estimate reverberation time (T60) from the observed reverberant speech signal using deep neural network (DNN). Reverberation of speech signal is a critical issue in speech processing as the reverberation results smearing of the sound characteristics in both temporal and spectral domain resulting unfavorable effects on the performance of speech processing algorithms. Employing room acoustic characteristics of a reverberant speech can enhance the performance of the speech processing system so that the blind estimation of reverberation time has been studied based on the numerical interpretation of reverberation. In this paper, we adopt the speech decay rate and its distribution for each frequency bin as input feature vectors of DNN. Complex relation between each input feature vector and each T60 target label through multiple nonlinear hidden layers. We also introduce an approach to mitigate the computational complexity whilst maintaining rational performance.
