Predicting phoneme-level prosody latents using AR and flow-based Prior Networks for expressive speech synthesis

no code implementations2 Nov 2022 Konstantinos Klapsas, Karolos Nikitaras, Nikolaos Ellinas, June Sig Sung, Inchul Hwang, Spyros Raptis, Aimilios Chalamandaris, Pirros Tsiakoulis

A large part of the expressive speech synthesis literature focuses on learning prosodic representations of the speech signal which are then modeled by a prior distribution during inference.

Generating Gender-Ambiguous Text-to-Speech Voices

no code implementations1 Nov 2022 Konstantinos Markopoulos, Georgia Maniati, Georgios Vamvoukakis, Nikolaos Ellinas, Karolos Nikitaras, Konstantinos Klapsas, Georgios Vardaxoglou, Panos Kakoulidis, June Sig Sung, Inchul Hwang, Aimilios Chalamandaris, Pirros Tsiakoulis, Spyros Raptis

While a female voice is a common choice, there is an increasing interest in alternative approaches where the gender is ambiguous rather than clearly identifying as female or male.

Learning utterance-level representations through token-level acoustic latents prediction for Expressive Speech Synthesis

no code implementations1 Nov 2022 Karolos Nikitaras, Konstantinos Klapsas, Nikolaos Ellinas, Georgia Maniati, June Sig Sung, Inchul Hwang, Spyros Raptis, Aimilios Chalamandaris, Pirros Tsiakoulis

We show that the fine-grained latent space also captures coarse-grained information, which is more evident as the dimension of latent space increases in order to capture diverse prosodic representations.

Cross-lingual Text-To-Speech with Flow-based Voice Conversion for Improved Pronunciation

no code implementations31 Oct 2022 Nikolaos Ellinas, Georgios Vamvoukakis, Konstantinos Markopoulos, Georgia Maniati, Panos Kakoulidis, June Sig Sung, Inchul Hwang, Spyros Raptis, Aimilios Chalamandaris, Pirros Tsiakoulis

When used in a cross-lingual setting, acoustic features are initially produced with a native speaker of the target language and then voice conversion is applied by the same model in order to convert these features to the target speaker's voice.

Fine-grained Noise Control for Multispeaker Speech Synthesis

no code implementations11 Apr 2022 Karolos Nikitaras, Georgios Vamvoukakis, Nikolaos Ellinas, Konstantinos Klapsas, Konstantinos Markopoulos, Spyros Raptis, June Sig Sung, Gunu Jho, Aimilios Chalamandaris, Pirros Tsiakoulis

A text-to-speech (TTS) model typically factorizes speech attributes such as content, speaker and prosody into disentangled representations. Recent works aim to additionally model the acoustic conditions explicitly, in order to disentangle the primary speech factors, i. e. linguistic content, prosody and timbre from any residual factors, such as recording conditions and background noise. This paper proposes unsupervised, interpretable and fine-grained noise and prosody modeling.

Word-Level Style Control for Expressive, Non-attentive Speech Synthesis

no code implementations19 Nov 2021 Konstantinos Klapsas, Nikolaos Ellinas, June Sig Sung, Hyoungmin Park, Spyros Raptis

This paper presents an expressive speech synthesis architecture for modeling and controlling the speaking style at a word level.

Using Audio Books for Training a Text-to-Speech System

no code implementations LREC 2014 Chalam, Aimilios aris, Pirros Tsiakoulis, Sotiris Karabetsos, Spyros Raptis

Creating new voices for a TTS system often requires a costly procedure of designing and recording an audio corpus, a time consuming and effort intensive task.
