NESC: Robust Neural End-2-End Speech Coding with GANs
Nicola Pia, Kishan Gupta, Srikanth Korse +2
Neural networks have proven to be a formidable tool to tackle the problem of speech coding at very low bit rates. However, the design of a neural coder that can be operated robustl…
PostGAN: A GAN-Based Post-Processor to Enhance the Quality of Coded Speech
Srikanth Korse, Nicola Pia, Kishan Gupta +1
The quality of speech coded by transform coding is affected by various artefacts especially when bitrates to quantize the frequency components become too low. In order to mitigate…
A DNN Based Post-Filter to Enhance the Quality of Coded Speech in MDCT Domain
Kishan Gupta, Srikanth Korse, Bernd Edler +1
Frequency domain processing, and in particular the use of Modified Discrete Cosine Transform (MDCT), is the most widespread approach to audio coding. However, at low bitrates, audi…
