Improving Audiovisual Speech Recognition through Synthetic Visual Data Augmentation
Pol Buitrago, Pol Gàlvez, Javier Hernando
Audiovisual Speech Recognition (AVSR) is a multimodal approach to speech recognition that incorporates visual information from lip movements to enhance model performance. Despite i…
Disentangling Speaker and Language Effects in Cross-Lingual Speaker Verification for Iberian Languages
Pol Buitrago, Javier Hernando
Cross-lingual speaker verification (SV) systems typically exhibit performance degradation when enrollment and test utterances are spoken in different languages. However, standard e…
How Attention Shapes Emotion: A Comparative Study of Attention Mechanisms for Speech Emotion Recognition
Marc Casals-Salvador, Federico Costa, Rodolfo Zevallos +1
Speech Emotion Recognition (SER) plays a key role in advancing human-computer interaction. Attention mechanisms have become the dominant approach for modeling emotional speech due…
Bootstrapping Audiovisual Speech Recognition in Zero-AV-Resource Scenarios
Pol Buitrago, Pol Gàlvez, Oriol Pareras +1
Audiovisual speech recognition (AVSR) combines acoustic and visual cues to improve transcription robustness under challenging conditions but remains out of reach for most under-res…
Quantifying Cross-Lingual Transfer in Paralinguistic Speech Tasks
Pol Buitrago, Oriol Pareras, Federico Costa +1
Paralinguistic speech tasks are often considered relatively language-agnostic, as they rely on extralinguistic acoustic cues rather than lexical content. However, prior studies rep…
