Speech Quality Estimation

The issue of evaluating the performance of a new signal enhancement system is time-consuming and tedious, therefore, availability of a reliable instrumental metric for predicting the subjective listening results is of great importance in the development or implementation of a new method. Here we present contributions focused on studying the reliability of the existing metrics in prediction of perceived quality or speech intelligibility achievable of a single-channel signal enhancement method. For a recent overview on the speech quality estimation we refer to "Ch. 6 in the book".
