Investigating the Utility of Surprisal from Large Language Models for Speech Synthesis Prosody

no code implementations16 Jun 2023 Sofoklis Kakouros, Juraj Šimko, Martti Vainio, Antti Suni

We explore how word surprisal extracted from large language models (LLMs) correlates with word prominence, a signal-based measure of the salience of a word in a given discourse.

The Power of Prosody and Prosody of Power: An Acoustic Analysis of Finnish Parliamentary Speech

no code implementations25 May 2023 Martti Vainio, Antti Suni, Juraj Šimko, Sofoklis Kakouros

Parliamentary recordings provide a rich source of data for studying how politicians use speech to convey their messages and influence their audience.

North Sámi Dialect Identification with Self-supervised Speech Models

1 code implementation19 May 2023 Sofoklis Kakouros, Katri Hiovain-Asikainen

The North S\'{a}mi (NS) language encapsulates four primary dialectal variants that are related but that also have differences in their phonology, morphology, and vocabulary.

Dialect Identification

What does BERT learn about prosody?

no code implementations25 Apr 2023 Sofoklis Kakouros, Johannah O'Mahony

Language models have become nearly ubiquitous in natural language processing applications achieving state-of-the-art results in many tasks including prosody.

Speech-based emotion recognition with self-supervised models using attentive channel-wise correlations and label smoothing

no code implementations3 Nov 2022 Sofoklis Kakouros, Themos Stafylakis, Ladislav Mosner, Lukas Burget

When recognizing emotions from speech, we encounter two common problems: how to optimally capture emotion-relevant information from the speech signal and how to best quantify or categorize the noisy subjective emotion labels.

Emotion Recognition

Extracting speaker and emotion information from self-supervised speech models via channel-wise correlations

no code implementations15 Oct 2022 Themos Stafylakis, Ladislav Mosner, Sofoklis Kakouros, Oldrich Plchot, Lukas Burget, Jan Cernocky

Self-supervised learning of speech representations from large amounts of unlabeled data has enabled state-of-the-art results in several speech processing tasks.
