Abstract: This paper introduces V2Coder, a non-autoregressive vocoder based on hierarchical variational autoencoders (VAEs). The hierarchical VAE with hierarchically extended prior and approximate ...

This project develops tools for interfacing with Advanced Multiband Excitation (AMBE) hardware vocoder chips developed by Digital Voice Systems, Inc. (DVSI). The proprietary AMBE technology is used in ...

Abstract: Inspired by the success of deep neural networks (DNNs) in speech processing, this paper presents Deep Vocoder, a direct end-to-end low bit rate speech compression method with deep ...
