Can Bayesian Optimization Efficiently Find a Strong Single Expert in Neural Thickets?

Nigel Bastian Cendra, Abdelhamid Ezzerg, Fernando Julio Cendra +2

Gradient-free post-training has emerged as a compelling alternative to gradient-based optimization for large language models (LLMs), but existing approaches remain costly. We ask w…

Robust Bayesian Optimisation with Unbounded Corruptions

Abdelhamid Ezzerg, Ilija Bogunovic, Jeremias Knoblauch

Bayesian Optimization is critically vulnerable to extreme outliers. Existing provably robust methods typically assume a bounded cumulative corruption budget, which makes them defen…

AE-Flow: AutoEncoder Normalizing Flow

Jakub Mosiński, Piotr Biliński, Thomas Merritt +2

Recently normalizing flows have been gaining traction in text-to-speech (TTS) and voice conversion (VC) due to their state-of-the-art (SOTA) performance. Normalizing flows are unsu…

Creating New Voices using Normalizing Flows

Piotr Bilinski, Thomas Merritt, Abdelhamid Ezzerg +5

Creating realistic and natural-sounding synthetic speech remains a big challenge for voice identities unseen during training. As there is growing interest in synthesizing voices of…

Comparing normalizing flows and diffusion models for prosody and acoustic modelling in text-to-speech

Guangyan Zhang, Thomas Merritt, Manuel Sam Ribeiro +10

Neural text-to-speech systems are often optimized on L1/L2 losses, which make strong assumptions about the distributions of the target data space. Aiming to improve those assumptio…

Remap, warp and attend: Non-parallel many-to-many accent conversion with Normalizing Flows

Abdelhamid Ezzerg, Thomas Merritt, Kayoko Yanagisawa +6

Regional accents of the same language affect not only how words are pronounced (i.e., phonetic content), but also impact prosodic aspects of speech such as speaking rate and intona…

GlowVC: Mel-spectrogram space disentangling model for language-independent text-free voice conversion

Magdalena Proszewska, Grzegorz Beringer, Daniel Sáez-Trigueros +3

In this paper, we propose GlowVC: a multilingual multi-speaker flow-based model for language-independent text-free voice conversion. We build on Glow-TTS, which provides an archite…

Text-free non-parallel many-to-many voice conversion using normalising flows

Thomas Merritt, Abdelhamid Ezzerg, Piotr Biliński +4

Non-parallel voice conversion (VC) is typically achieved using lossy representations of the source speech. However, ensuring only speaker identity information is dropped whilst all…

Enhancing audio quality for expressive Neural Text-to-Speech

Abdelhamid Ezzerg, Adam Gabrys, Bartosz Putrycz +7

Artificial speech synthesis has made a great leap in terms of naturalness as recent Text-to-Speech (TTS) systems are capable of producing speech with similar quality to human recor…

Non-Autoregressive TTS with Explicit Duration Modelling for Low-Resource Highly Expressive Speech

Raahil Shah, Kamil Pokora, Abdelhamid Ezzerg +5

Whilst recent neural text-to-speech (TTS) approaches produce high-quality speech, they typically require a large amount of recordings from the target speaker. In previous work, a 3…
