Convolutional Neural Networks to Enhance Coded Speech

25 Jun 2018Ziyue ZhaoHuijun LiuTim Fingscheidt

Enhancing coded speech suffering from far-end acoustic background noise, quantization noise, and potentially transmission errors, is a challenging task. In this work we propose two postprocessing approaches applying convolutional neural networks (CNNs) either in the time domain or the cepstral domain to enhance the coded speech without any modification of the codecs...
