Low Bit-Rate Speech Coding with VQ-VAE and a WaveNet Decoder

no code implementations14 Oct 2019 Cristina Gârbacea, Aäron van den Oord, Yazhe Li, Felicia S. C. Lim, Alejandro Luebs, Oriol Vinyals, Thomas C. Walters

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.

Speech bandwidth extension with WaveNet

no code implementations5 Jul 2019 Archit Gupta, Brendan Shillingford, Yannis Assael, Thomas C. Walters

This paper proposes an approach where a communication node can instead extend the bandwidth of a band-limited incoming speech signal that may have been passed through a low-rate codec.

Wavenet based low rate speech coding

1 code implementation1 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.
