Voice Conversion for Lombard Speaking Style with Implicit and Explicit Acoustic Feature Conditioning

Dominika Woszczyk, Manuel Sam Ribeiro, Thomas Merritt +1

Text-to-Speech (TTS) systems in Lombard speaking style can improve the overall intelligibility of speech, useful for hearing loss and noisy conditions. However, training those mode…

Multilingual context-based pronunciation learning for Text-to-Speech

Giulia Comini, Manuel Sam Ribeiro, Fan Yang +2

Phonetic information and linguistic knowledge are an essential component of a Text-to-speech (TTS) front-end. Given a language, a lexicon can be collected offline and Grapheme-to-P…

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…

Improving grapheme-to-phoneme conversion by learning pronunciations from speech recordings

Manuel Sam Ribeiro, Giulia Comini, Jaime Lorenzo-Trueba

The Grapheme-to-Phoneme (G2P) task aims to convert orthographic input into a discrete phonetic representation. G2P conversion is beneficial to various speech processing application…

Predicting pairwise preferences between TTS audio stimuli using parallel ratings data and anti-symmetric twin neural networks

Cassia Valentini-Botinhao, Manuel Sam Ribeiro, Oliver Watts +2

Automatically predicting the outcome of subjective listening tests is a challenging task. Ratings may vary from person to person even if preferences are consistent across listeners…

Low-data? No problem: low-resource, language-agnostic conversational text-to-speech via F0-conditioned data augmentation

Giulia Comini, Goeric Huybrechts, Manuel Sam Ribeiro +2

The availability of data in expressive styles across languages is limited, and recording sessions are costly and time consuming. To overcome these issues, we demonstrate how to bui…
