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 Streamwise GAN Vocoder for Wideband Speech Coding at Very Low Bit Rate

Ahmed Mustafa, Jan Büthe, Srikanth Korse +3

Recently, GAN vocoders have seen rapid progress in speech synthesis, starting to outperform autoregressive models in perceptual quality with much higher generation speed. However,…

StyleMelGAN: An Efficient High-Fidelity Adversarial Vocoder with Temporal Adaptive Normalization

Ahmed Mustafa, Nicola Pia, Guillaume Fuchs

In recent years, neural vocoders have surpassed classical speech generation approaches in naturalness and perceptual quality of the synthesized speech. Computationally heavy models…

On the dynamics of some vector fields tangent to non-integrable plane fields

Nicola Pia

Let be a smooth -distribution on a smooth manifold of dimension and a line field such that $[\mathcal{W},\mathcal…

Riemannian properties of Engel structures

Nicola Pia

This paper is about geometric and Riemannian properties of Engel structures, i.e. maximally non-integrable -plane fields on -manifolds. Two -forms and are called E…
