Ultra-Low-Bitrate Speech Coding with Pretrained Transformers
Ali Siahkoohi, Michael Chinen, Tom Denton +2
Speech coding facilitates the transmission of speech over low-bandwidth networks with minimal distortion. Neural-network based speech codecs have recently demonstrated significant…
On the Relevance of Bandwidth Extension for Speaker Verification
Marcos Faundez-Zanuy, Mattias Nilsson, W. Bastiaan Kleijn
In this paper, we consider the effect of a bandwidth extension of narrow-band speech signals (0.3-3.4 kHz) to 0.3-8 kHz on speaker verification. Using covariance matrix based verif…
A DNN Optimizer that Improves over AdaBelief by Suppression of the Adaptive Stepsize Range
Guoqiang Zhang, Kenta Niwa, W. Bastiaan Kleijn
We make contributions towards improving adaptive-optimizer performance. Our improvements are based on suppression of the range of adaptive stepsizes in the AdaBelief optimizer. Fir…
On the relevance of bandwidth extension for speaker identification
Marcos Faundez-Zanuy, Mattias Nilsson, W. Bastiaan Kleijn
In this paper we discuss the relevance of bandwidth extension for speaker identification tasks. Mainly we want to study if it is possible to recognize voices that have been bandwit…
