Cardiotoxicidade: avaliação do strain da aurícula esquerda por ETT
Sousa, Rui; Silva, Joana; Henriques, Madalena; Cavaco, Sofia; Clérigo, Anália Matos; Fonseca, VirgíniaIntrodução: O cancro da mama é uma das neoplasias malignas mais prevalentes, sendo a cardiotoxicidade induzida pelo tratamento com antraciclinas e trastuzumab uma complicação importante, associada à disfunção miocárdica e à insuficiência cardíaca. O ecocardiograma transtorácico (ETT) é considerado o método gold standard na avaliação da função cardíaca, sendo a fração de ejeção do ventrículo esquerdo (FEVE) e o ...
The BioVisualSpeech european portuguese sibilants corpus
Grilo, Ana Margarida; Guimarães, Isabel; Ascensão, Mariana; Abad, Alberto; Anjos, Ivo; Magalhães, João; Cavaco, SofiaAbstract. The development of reliable speech therapy computer tools that automatically classify speech productions depends on the quality of the speech data set used to train the classi cation algorithms. The data set should characterize the population in terms of age, gender and native language, but it should also have other important properties that characterize the population that is going to use the tool. T...
The BioVisualSpeech corpus of words with sibilants for speech therapy games dev...
Cavaco, Sofia; Guimarães, Isabel; Ascensão, Mariana; Abad, Alberto; Anjos, Ivo; Oliveira, Francisco; Martins, Sofia; Marques, Nuno; Eskenazi, MaxineAbstract: In order to develop computer tools for speech therapy that reliably classify speech productions, there is a need for speech production corpora that characterize the target population in terms of age, gender, and native language. Apart from including correct speech productions, in order to characterize the target population, the corpora should also include samples from people with speech sound disorder...
Sibilant consonants classification with deep neural networks
Anjos, Ivo; Marques, Nuno; Grilo, Ana Margarida; Guimarães, Isabel; Magalhães, João; Cavaco, SofiaAbstract. Many children su ering from speech sound disorders cannot pronounce the sibilant consonants correctly. We have developed a serious game that is controlled by the children's voices in real time and that allows children to practice the European Portuguese sibilant consonants. For this, the game uses a sibilant consonant classi er. Since the game does not require any type of adult supervision, children c...
Detection of voicing and place of articulation of fricatives with deep learning...
Anjos, Ivo; Maxine, Eskenazi; Marques, Nuno; Grilo, Ana Margarida; Guimarães, Isabel; Magalhães, João; Cavaco, SofiaChildren with fricative distortion errors have to learn how to correctly use the vocal folds, and which place of articulation to use in order to correctly produce the different fricatives. Here we propose a virtual tutor for fricatives distortion correction. This is a virtual tutor for speech and language therapy that helps children understand their fricative production errors and how to correctly use their spe...
User experience of interactive technologies for people with dementia: comparati...
Ferreira, Luis Duarte Andrade; Ferreira, Henrique; Cavaco, Sofia; Cameirão, Mónica; Bermúdez i Badia, SergiBackground: Serious games (SGs) are used as complementary approaches to stimulate patients with dementia. However, many of the SGs use out-of-the-shelf technologies that may not always be suitable for such populations, as they can lead to negative behaviors, such as anxiety, fatigue, and even cybersickness. Objective: This study aims to evaluate how patients with dementia interact and accept 5 out-of-the-shelf ...

A model for sibilant distortion detection in children
Anjos, Ivo; Grilo, Ana Margarida; Ascensão, Mariana; Guimarães, Isabel; Magalhães, João; Cavaco, SofiaThe distortion of sibilant sounds is a common type of speech sound disorder in European Portuguese speaking children. Speech and language pathologists (SLP) use different types of speech production tasks to assess these distortions. One of these tasks consists of the sustained production of isolated sibilants. Using these sound productions, SLPs usually rely on auditory perceptual evaluation to assess the sibil...
A serious mobile game with visual feedback for training sibilant consonants
Anjos, Ivo; Grilo, Ana Margarida; Ascensão, Mariana; Guimarães, Isabel; Magalhães, João; Cavaco, SofiaAbstract. The distortion of sibilant sounds is a common type of speech sound disorder (SSD) in Portuguese speaking children. Speech and language pathologists (SLP) frequently use the isolated sibilants exercise to assess and treat this type of speech errors. While technological solutions like serious games can help SLPs to motivate the children on doing the exercises repeatedly, there is a lack of such games fo...
3D facial video retrieval and management for decision support in speech and lan...
Carrapiço, Ricardo; Guimarães, Isabel; Grilo, Ana Margarida; Cavaco, Sofia; Magalhães, João3D video is introducing great changes in many health related areas. The realism of such information provides health professionals with strong evidence analysis tools to facilitate clinical decision processes. Speech and language therapy aims to help subjects in correcting several disorders. The assessment of the patient by the speech and language therapist (SLT), requires several visual and audio analysis proce...
