This paper presents an acoustic-prosodic analysis of entrainment in map-task dialogues in European Portuguese. Our main goal is to analyze how turn-by-turn entrainment varies with distinct structural metadata events: types of sentence-like units (SUs) in consecutive turns (e.g. interrogatives followed by declaratives, or both declaratives), and with the presence of discourse markers, affirmative cue words, and ...
This paper presents a global analysis of entrainment in map-task dialogues in European Portuguese, including 48 dialogues, between 24 speakers. Our main goal is to analyze the acoustic-prosodic similarities between speaker pairs, namely if there are global entrainment cues displayed in the dialogues, if entrainment is manifested in distinct sets of features shared amongst the speakers, if entrainment depends on...
Nas línguas gestuais, as conexões interfrásicas não são sempre explícitas nem tão facilmente identificáveis como nas línguas orais/escritas, uma vez que tendem a configurar- se em elementos não lexicais. O presente estudo procura descrever as estruturas relacionadas com os diferentes valores associados ao conector “e”, em língua gestual portuguesa (LGP). O desafio reside no facto de o conector copulativo, além ...
This paper performs a global analysis of entrainment between dyads in map-task dialogues in European Portuguese (EP), including 48 dialogues, between 24 speakers. Our main goals focus on the acoustic-prosodic similarities between speakers, namely if there are global entrainment cues displayed in the dialogues, if there are degrees of entrainment manifested in distinct sets of features shared amongst the speaker...
This work describes a framework that encompasses multi-layered linguistic information, focusing on prosodic features (pitch, energy, and tempo patterns), uses such features to distinguish between sentence-form types and disfluency/fluency repairs, and contributes to the characterization of intonational patterns of spontaneous and prepared speech in European Portuguese. Different machine learning methods have be...
This work describes the discourse markers present in two corpora for European Portuguese, in different domains (university lectures and map-task dialogues). In this study, we also perform a multiclass automatic classification task based on prosodic features to verify in both corpora which words are discourse markers, which are disfluencies, and which are sentence like-units (SUs). Results show that the selectio...
Neste capítulo apresentamos um olhar panorâmico sobre a variação prosódica e sobre a sua interface com a área do processamento automático de fala. Tendo por base essencialmente a investigação que tem sido desenvolvida no português europeu sobre corpora de fala espontânea e preparada, em contextos de exposição e de interação, nomeadamente na variedade padrão falada em Lisboa, analisamos a variação da entoação em...
The present study aims to investigate intonation contours in phrase-final position, in a corpus of spontaneous and prepared unscripted presentations from teenagers (14-15 years old) and adults, collected in a school context. Taking into account the differences between phrasing levels (ToBI breaks 3 and 4), we show that the frequency of low/falling vs. high/rising contours – mainly (H+)L* L and (L+)H* H – varies...
The first contribution of this study is the description of the prosodic behavior of discourse markers present in two speech corpora of European Portuguese (EP) in different domains (university lectures, and map-task dialogues). The second contribution is a multiclass classification to verify, given their prosodic features, which words in both corpora are classified as discourse markers, which are disfluencies, ...
We present a corpus of European Portuguese spoken by teenagers and adults in school context, CPE-FACES, with an overview of the differential characteristics of high school oral presentations and the challenges this data poses to automatic speech processing. The CPE-FACES corpus has been created with two main goals: to provide a resource for the study of prosodic patterns in both spontaneous and prepared unscrip...
