Assessment of Parkinson’s disease medication state through automatic speech ana...
Pompili, Anna; Solera-Urena, Rubén; Abad, Alberto; Cardoso, Rita; Guimarães, Isabel; Fabbri, Margherita; Martins, Isabel P; Ferreira, JoaquimParkinson’s disease (PD) is a progressive degenerative disorder of the central nervous system characterized by motor and nonmotor symptoms. As the disease progresses, patients alternate periods in which motor symptoms are mitigated due to medication intake (ON state) and periods with motor complications (OFF state). The time that patients spend in the OFF condition is currently the main parameter employed to as...

A semi-supervised learning approach for automatic personality classification ba...
Solera-Ureña, Rubén; Moniz, Helena; Batista, Fernando; Cabarrão, Vera; Pompili, Anna; Fernández-Astudillo, Ramón; Trancoso, IsabelAutomatic personality analysis has gained great attention in the last years as a fundamental dimension in human-machine interactions. However, the development of this technology in some domains, such as the classification of children’s personality, has been hindered by the limited number and size of the available speech corpora due to ethical concerns on collecting such corpora. To circumvent the lack of data, ...
ALBAYZIN Query-by-example Spoken Term Detection 2016 evaluation
Tejedor, Javier; Toledano, Doroteo T.; Lopez-Otero, Paula; Docio-Fernandez, Laura; Proença, Jorge; Perdigão, Fernando; García-Granada, FernandoQuery-by-example Spoken Term Detection (QbE STD) aims to retrieve data from a speech repository given an acoustic (spoken) query containing the term of interest as the input. This paper presents the systems submitted to the ALBAYZIN QbE STD 2016 Evaluation held as a part of the ALBAYZIN 2016 Evaluation Campaign at the IberSPEECH 2016 conference. Special attention was given to the evaluation design so that a tho...
Automatic detection of Parkinson’s disease: an experimental analysis of common ...
Pompili, Anna; Abad, Alberto; Romano, Paolo; Martins, Isabel P; Cardoso, Rita; Santos, Helena; Carvalho, Joana; Guimarães, Isabel; Ferreira, JoaquimParkinson’s disease (PD) is the second most common neurodegenerative disorder of mid-to-late life after Alzheimer’s disease. During the progression of the disease, most individuals with PD report impairments in speech due to deficits in phonation, articulation, prosody, and fluency. In the literature, several studies perform the automatic classification of speech of people with PD considering various types of a...
Automatic Recognition of Prosodic Patterns in Semantic Verbal Fluency Tests - a...
Moniz, Helena; Pompili, Anna; Batista, Fernando; Trancoso, Isabel; Abad, Alberto; Amorim, CristianaThis paper automatically detects prosodic patterns in the domain of semantic fluency tests. Verbal fluency tests aim at evaluating the spontaneous production of words under constrained conditions. Mostly used for assessing cognitive impairment, they can be used in a plethora of domains, as edutainment applications or games with educational purposes. This work discriminates between list effects, disfluencies, an...
