Robust front-end for audio, visual and audio–visual speech classification
(Springer, 2018-06)
This paper proposes a robust front-end for speech classification which can be employed with acoustic, visual or audio–visual information, indistinctly. Wavelet multiresolution analysis is employed to represent temporal ...
Sistemas de análisis acústico y de reconocimiento automático en habla espontáneaAcoustic Analysis and Automatic Recognition Systems in spontaneous speech
(Universidad de Ciencias Empresariales y Sociales, 2010-12)
En este trabajo se presentan dos sistemas de análisis acústico del habla con aplicaciones a la descripción de segmentos de discurso espontáneo y un sistema de reconocimiento automático de habla espontánea orientado a la ...
Enhancement of the medial olivocochlear system prevents hidden hearing loss
(Society for Neuroscience, 2018-08)
Cochlear synaptopathy produced by exposure to noise levels that cause only transient auditory threshold elevations is a condition that affects many people and is believed to contribute to poor speech discrimination in noisy ...
Automatic word count estimation from daylong child-centered recordings in various language environments using language-independent syllabification of speech
(Elsevier, 2019-10)
Automatic word count estimation (WCE) from audio recordings can be used to quantify the amount of verbal communication in a recording environment. One key application of WCE is to measure language input heard by infants ...
Emotional salience enhances intelligibility in adverse acoustic conditions
(Elsevier, 2020-10)
Introduction: Emotion facilitates word recognition under adverse acoustic conditions. We use an auditory emotional paradigm to evaluate the ability to distinguish words from irrelevant random stimuli, elucidating its neural ...
Reply to: ''Does Cognitive Impairment Influence Motor Speech Performance in De Novo Parkinson's Disease''
(Wiley-liss, div John Wiley & Sons Inc., 2021-12-17)
We appreciate the letter by Rusz and Tykalová as a valuable contribution to dysarthria assessments in Parkinson's disease (PD). Their report partly mirrors our methodological approach, with converging results and key ...
El ritmo del español y el del inglés: Repercusiones metodológicas sobre su medición acústicaSpeech rhythm in Spanish and English: Methodological implications about its acoustic measurement
(Universidad Nacional del Comahue. Facultad de Lenguas, 2018-11)
Desde un abordaje fonológico, el ritmo de habla se considera como la suma de diversas propiedades fonético-fonológicas, como la estructura silábica, el rol del acento y la reducción vocálica. El español y el inglés representan ...
Spoken emotion recognition using hierarchical classifiers
(Elsevier, 2011-07)
The recognition of the emotional state of speakers is a multi-disciplinary research area that has received great interest over the last years. One of the most important goals is to improve the voice-based human-machine ...
A cross-linguistic analysis of the temporal dynamics of turn-taking cues using machine learning as a descriptive tool
(Elsevier Science, 2020-12)
In dialogue, speakers produce and perceive acoustic/prosodic turn-taking cues, which are fundamental for negotiating turn exchanges with their interlocutors. However, little of the temporal dynamics and cross-linguistic ...
Aplicación de métodos acústicos lineales y no lineales en parálisis cordales unilateralesApplication of Acoustic Methods Linear and Non Linear in Chordal Unilateral Paralysis
(Corporación Universitaria Iberoamericana, 2012-11)
Se presenta una nueva metodología que combina el análisis acústico y perceptual tradicional con algoritmos de la dinámica no lineal. Específicamente, coeficientes de Lyapunov aplicados a la medición de voces con alta ...
