Generative Speech Coding with Predictive Variance Regularization

1 code implementation • 18 Feb 2021 • W. Bastiaan Kleijn, Andrew Storus, Michael Chinen, Tom Denton, Felicia S. C. Lim, Alejandro Luebs, Jan Skoglund, Hengchin Yeh

We introduce predictive-variance regularization to reduce the sensitivity to outliers, resulting in a significant increase in performance.

In order to efficiently transmit and store speech signals, speech codecs create a minimally redundant representation of the input signal which is then decoded at the receiver with the best possible perceptual quality.

Wavenet based low rate speech coding

1 code implementation • 1 Dec 2017 • W. Bastiaan Kleijn, Felicia S. C. Lim, Alejandro Luebs, Jan Skoglund, Florian Stimberg, Quan Wang, Thomas C. Walters

Traditional parametric coding of speech facilitates low rate but provides poor reconstruction quality because of the inadequacy of the model used.
