Benchmarking Adult Addressee Classification Across Child- and Adult-Directed Speech Datasets
Sofoklis Kakouros, Daniil Kocharov, Okko Räsänen
In this work, we present a comprehensive analysis of classification performance for distinguishing child-directed speech (CDS) from adult-directed speech (ADS) using speech data fr…
Cross-linguistic Prosodic Analysis of Autistic and Non-autistic Child Speech in Finnish, French and Slovak
Ida-Lotta Myllylä, Sofoklis Kakouros
Prosodic differences in autism are well-documented, but cross-linguistic evidence remains limited. This study investigates prosody in autism across a multilingual corpus of Finnish…
Classification of Autistic and Non-Autistic Children's Speech: A Cross-Linguistic Study in Finnish, French, and Slovak
Sofoklis Kakouros, Ida-Lotta Myllylä
We present a cross-linguistic study of speech in autistic and non-autistic children speaking Finnish, French, and Slovak. We combine supervised classification with within-language…
iMiGUE-Speech: A Spontaneous Speech Dataset for Affective Analysis
Sofoklis Kakouros, Fang Kang, Haoyu Chen
This work presents iMiGUE-Speech, an extension of the iMiGUE dataset that provides a spontaneous affective corpus for studying emotional and affective states. The new release focus…
Investigating the Utility of Surprisal from Large Language Models for Speech Synthesis Prosody
Sofoklis Kakouros, Juraj Šimko, Martti Vainio +1
This paper investigates the use of word surprisal, a measure of the predictability of a word in a given context, as a feature to aid speech synthesis prosody. We explore how word s…
The Power of Prosody and Prosody of Power: An Acoustic Analysis of Finnish Parliamentary Speech
Martti Vainio, Antti Suni, Juraj Šimko +1
Parliamentary recordings provide a rich source of data for studying how politicians use speech to convey their messages and influence their audience. This provides a unique context…
North Sámi Dialect Identification with Self-supervised Speech Models
Sofoklis Kakouros, Katri Hiovain-Asikainen
The North Sámi (NS) language encapsulates four primary dialectal variants that are related but that also have differences in their phonology, morphology, and vocabulary. The unique…
Speech-based emotion recognition with self-supervised models using attentive channel-wise correlations and label smoothing
Sofoklis Kakouros, Themos Stafylakis, Ladislav Mosner +1
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 ca…
Extracting speaker and emotion information from self-supervised speech models via channel-wise correlations
Themos Stafylakis, Ladislav Mosner, Sofoklis Kakouros +3
Self-supervised learning of speech representations from large amounts of unlabeled data has enabled state-of-the-art results in several speech processing tasks. Aggregating these s…
Prosodic Prominence and Boundaries in Sequence-to-Sequence Speech Synthesis
Antti Suni, Sofoklis Kakouros, Martti Vainio +1
Recent advances in deep learning methods have elevated synthetic speech quality to human level, and the field is now moving towards addressing prosodic variation in synthetic speec…
Dialect Identification of Spoken North Sámi Language Varieties Using Prosodic Features
Sofoklis Kakouros, Katri Hiovain, Martti Vainio +1
This work explores the application of various supervised classification approaches using prosodic information for the identification of spoken North Sámi language varieties. Dialec…
