Objective no-reference assessment method of broadcast speech quality

In this paper, based on the existing no-reference assessment method for low-bandwidth speech, an algorithm for broadcast speech quality is proposed after the application scenarios of high bandwidth voice analyzed, which consists of preprocessing, extraction of speech features, reconstruction of reference signal, full-reference evaluation, and multi-layer perceptual neural network mapping. It is shown in experimental results that the algorithm can be used as a reliable basis to a certain extent for the quality of broadcast speech in the case of failure to obtain the reference signal.
