Adaptations in Speech Processing

, 2021
Wie sich die Sprachwahrnehmung an ständig eingehende Informationen anpasst, ist eine Schlüsselfrage in der Gedanken- und Gehirnforschung. Die vorliegende Dissertation zielt darauf ab, zum Verständnis von Anpassungen an die Sprecheridentität und Sprachfehler während der Sprachverarbeitung beizutragen und unser Wissen über die Rolle der kognitiven ...

NMF-weighted SRP for multi-speaker direction of arrival estimation: robustness to spatial aliasing while exploiting sparsity in the atom-time domain

EURASIP Journal on Audio, Speech, and Music Processing, 2021
Localization of multiple speakers using microphone arrays remains a challenging problem, especially in the presence of noise and reverberation. State-of-the-art localization algorithms generally exploit the sparsity of speech in some representation for ...

Elastic CRFs for Open-Ontology Slot Filling

Applied Sciences, 2021
Slot filling is a crucial component in task-oriented dialog systems that is used to parse (user) utterances into semantic concepts called slots. An ontology is defined by the collection of slots and the values that each slot can take.

Coarticulation vs Phonologization: Evidence from Southern Italo-Romance [PDF]

JASA Express Letters
This study compares the variety of Italian spoken in Campania and the Italo-Romance variety of Mormanno (Calabria) to investigate the acoustic differences between phonetic vowel-to-vowel coarticulation and phonologized metaphony.

Effective Exploitation of Posterior Information for Attention-Based Speech Recognition

IEEE Access, 2020
End-to-end attention-based modeling is increasingly popular for tackling sequence-to-sequence mapping tasks. Traditional attention mechanisms utilize prior input information to derive attention, which then conditions the output.
