A Variance Reduction Method for Neural-based Divergence Estimation

no code implementations29 Sep 2021 Jeremiah Birrell, Markos A. Katsoulakis, Yannis Pantazis, Dipjyoti Paul, Anastasios Tsourtis

Unfortunately, the approximation of expectations that are inherent in variational formulas by statistical averages can be problematic due to high statistical variance, e. g., exponential for the Kullback-Leibler divergence and certain estimators.

Enhancing Speech Intelligibility in Text-To-Speech Synthesis using Speaking Style Conversion

1 code implementation13 Aug 2020 Dipjyoti Paul, Muhammed PV Shifas, Yannis Pantazis, Yannis Stylianou

Intelligibility enhancement as quantified by the Intelligibility in Bits (SIIB-Gauss) measure shows that the proposed Lombard-SSDRC TTS system shows significant relative improvement between 110% and 130% in speech-shaped noise (SSN), and 47% to 140% in competing-speaker noise (CSN) against the state-of-the-art TTS approach.

Speaker Conditional WaveRNN: Towards Universal Neural Vocoder for Unseen Speaker and Recording Conditions

1 code implementation9 Aug 2020 Dipjyoti Paul, Yannis Pantazis, Yannis Stylianou

In terms of performance, our system has been preferred over the baseline TTS system by 60% over 15. 5% and by 60. 9% over 32. 6%, for seen and unseen speakers, respectively.

Cumulant GAN

no code implementations11 Jun 2020 Yannis Pantazis, Dipjyoti Paul, Michail Fasoulakis, Yannis Stylianou, Markos Katsoulakis

In this paper, we propose a novel loss function for training Generative Adversarial Networks (GANs) aiming towards deeper theoretical understanding as well as improved stability and performance for the underlying optimization problem.

Training Generative Adversarial Networks with Weights

no code implementations6 Nov 2018 Yannis Pantazis, Dipjyoti Paul, Michail Fasoulakis, Yannis Stylianou

The impressive success of Generative Adversarial Networks (GANs) is often overshadowed by the difficulties in their training.

Robustness of Voice Conversion Techniques Under Mismatched Conditions

no code implementations22 Dec 2016 Monisankha Pal, Dipjyoti Paul, Md Sahidullah, Goutam Saha

Most of the existing studies on voice conversion (VC) are conducted in acoustically matched conditions between source and target signal.
