Listeners of various languages tend to perceive an illusory vowel inside consonant clusters that are illegal in their native language. Here, we test whether this phenomenon arises after phoneme categorization or rather interacts with it. We assess the perception of illegal consonant clusters in native speakers of Japanese, Brazilian Portuguese, and European(More)
The Intonational Phrase organization of a sentence is a hybrid beast. It sometimes shows a tight correlation with the semantic properties of the sentence, namely what the sentence means in standard truth conditional terms. It sometimes appears to be a reflex of the Focus structure of the sentence. Sometimes it appears to be correlated with the length of the(More)
This paper investigates the acquisition of prosodic words in European Portuguese (EP) through analysis of grammatical and statistical properties of the target language and child speech. The analysis of grammatical properties shows that there are solid cues to the prosodic word (PW) in EP, and the presence of early word-based phonology in child speech shows(More)
In this study, the scaling of utterance-initial f0 values and H initial peaks are examined in several Romance languages as a function of phrasal length, measured in number of pitch accents (1 to 3 pitch accents) and in number of syllables (3 to 15). The motivation for this study stems from contradictory claims in the literature regarding whether the height(More)
INTRODUCTION Individuals with Parkinson's disease (PD) have to deal with several aspects of voice and speech decline and thus alteration of communication ability during the course of the disease. Among these communication impairments, 3 major challenges include: (1) dysarthria, consisting of orofacial motor dysfunction and dysprosody, which is linked to the(More)
This paper reports on two discrimination experiments involving Portuguese data. The findings support the prosodic contrast between EP and BP and stress the role played by intonation in this contrast. They also show that the perceptual distance between EP and BP is smaller than that between EP and Dutch. The robust distinction between EP and Dutch provides(More)
This paper describes the rhythmic properties of two central-southern varieties of European Portuguese (Ale and Alg), following similar methodologies of previous production and perception studies of rhythm in Portuguese. The analysis of production data showed that Ale presents a mixed rhythmic nature, whereas Alg is clearly stress-timed. The use of different(More)
The importance of frequency for phonological phenomena has long been noticed in the literature. However, frequency information available for phonological units in Portuguese is scarce, non-replicable, corpus dependent, and hard to obtain due to the non-existence of a free tool for public use. This paper describes FreP, a new electronic tool that provides(More)
