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 constituents of a sentence. And sometimes it seems merely to reflect a stylistic option in the utterance of a sentence. This paper centers on the ways in which intonational phrasing in phonological representation is dependent on the properties of the interface syntactic representation, giving but a nod to other factors. It assumes a grammatical architecture in which syntax mediates between phonology and semantics and where the syntax-phonology interface is characterized in terms of a set of optimality theoretic interface constraints (cf. Selkirk 1995, Truckenbrodt 1999).

The subject matter of the dissertation is the prosodic word. It bears on the organization of grammar and phonology, its interface with morphology and syntax, and the nature of phonological representations. Despite the reference to various other languages, it primarily focuses on European Portuguese (EP).

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 that EP children are aware of these cues. It is thus hypothesized that grammatical properties could play a role in the development of the PW by promoting the early production of the different word shapes found in the language. The analysis of statistical properties of the input, namely word shape frequencies in adult speech and child-directed speech, shows that they constrain early word shapes in child speech in ways similar to recent reports on other languages: a fairly high frequency of monosyllabic shapes, and especially of monosyllabic CV shapes, in the input agrees with the production of subminimal words in child speech; a fairly high frequency of trisyllabic and larger shapes in the input (adult speech in particular) matches the early development of words larger than a binary foot. These patterns, together with the co-occurrence of truncation to subminimal shapes in the initial and later stages, as well as the presence of prosodic fillers regardless of word size, support the claim that early words in EP are not constrained by minimality or maximality requirements. The potential interaction of grammar and frequency effects in PW acquisition is discussed in the light of the present findings and comparable data available in the literature for English, French, Spanish and Catalan.

OBJECTIVE To review studies on the readability of package leaflets of medicinal products for human use. METHODS We conducted a systematic literature review between 2008 and 2013 using the keywords “Readability and Package Leaflet” and “Readability and Package Insert” in the academic search engine Biblioteca do Conhecimento Online, comprising different bibliographic resources/databases. The preferred reporting items for systematic reviews and meta-analyses criteria were applied to prepare the draft of the report. Quantitative and qualitative original studies were included. Opinion or review studies not written in English, Portuguese, Italian, French, or Spanish were excluded. RESULTS We identified 202 studies, of which 180 were excluded and 22 were enrolled [two enrolling healthcare professionals, 10 enrolling other type of participants (including patients), three focused on adverse reactions, and 7 descriptive studies]. The package leaflets presented various readability problems, such as complex and difficult to understand texts, small font size, or few illustrations. The main methods to assess the readability of the package leaflet were usability tests or legibility formulae. Limitations with these methods included reduced number of participants; lack of readability formulas specifically validated for specific languages (e.g., Portuguese); and absence of an assessment on patients literacy, health knowledge, cognitive skills, levels of satisfaction, and opinions. CONCLUSIONS Overall, the package leaflets presented various readability problems. In this review, some methodological limitations were identified, including the participation of a limited number of patients and healthcare professionals, the absence of prior assessments of participant literacy, humor or sense of satisfaction, or the predominance of studies not based on role-plays about the use of medicines. These limitations should be avoided in future studies and be considered when interpreting the results.

Prosodies is a collection of recent papers in phonetics and phonology. It deals with a wide range of subjects like intonation, prosodic phrasing, rhythm, word stress, phrasal prominence, syllable structure, segmental variation and change, and the perception of segments, features, and their acoustic properties. The book is particularly valuable because it focuses on languages largely underrepresented in the literature, e.g., Cairene and Lebanese Arabic, Central Catalan and insular dialects of Catalan, Galician, Italian, Standard and Northern European Portuguese, Brazilian Portuguese, Peninsular Spanish and different varieties of Argentine Spanish.

Abstract In this article, a prosodic domain located between the prosodic word and the phonological phrase is argued for (the prosodic word group – PWG). This constituent groups the members of several types of compound-like expressions, but does not play a special part in the prosodic organization of clitics, and thus is argued to be (partially) distinct from the old clitic group (Hayes, The prosodic hierarchy in meter, Academic Press, 1989; Nespor and Vogel, Prosodic phonology, Foris, 1986). The PWG is shown to play a role in the phonology of compound-like expressions in a great number of languages, belonging to different linguistic families. Evidence is multifarious, coming from segmental, tonal, duration and prominence related phenomena. Crucially, evidence is also offered against an analysis resorting to recursive prosodic words – e.g., prominence patterns at the levels of the Prosodic Word (PW) and PWG may be reversed; phonological phenomena distinguishing the two domains show a difference in kind and not just in strength (Ladd, Intonational phonology, Cambridge University Press, 1996/2008; Frota, Prosody and focus in European Portuguese. Phonological phrasing and intonation, Garland Publishing, 2000).

ABSTRACT Infants perceive intonation contrasts early in development in contrast to lexical stress but similarly to lexical pitch accent. Previous studies have mostly focused on pitch height/direction contrasts; however, languages use a variety of pitch features to signal meaning, including differences in pitch timing. In this study, we investigate infants’ perception of the prosodic contrast that cues the difference between all-new information (broad focus) and the highlighting of a particular word (narrow/contrastive focus) in European Portuguese (EP), and which has been described as having pitch timing as its key feature. Using a modified version of the visual habituation paradigm, EP learning infants discriminated this contrast at 12 months but not at 7 months, deviating from previous findings of a precocious ability to perceive pitch distinctions. These results suggest different developmental trajectories of the perception of different prosodic contrasts, underlining the importance of the nature of the cues signalling a given contrast in a given language.

Introduction Individuals with Parkinsons 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 neurodegenerative processes; (2) effects of the pharmacological treatment, which vary according to the disease stage; and (3) particular speech modifications that may be language-specific, that is, dependent on the language spoken by the patients. The main objective of the FraLusoPark project is to provide a thorough evaluation of changes in PD speech as a result of pharmacological treatment and disease duration in 2 different languages (French vs European Portuguese). Methods and analysis Individuals with PD are enrolled in the study in France (N=60) and Portugal (N=60). Their global motor disability and orofacial motor functions is assessed with specific clinical rating scales, without (OFF) and with (ON) pharmacological treatment. 2 groups of 60 healthy age-matched volunteers provide the reference for between-group comparisons. Along with the clinical examinations, several speech tasks are recorded to obtain acoustic and perceptual measures. Patient-reported outcome measures are used to assess the psychosocial impact of dysarthria on quality of life. Ethics and dissemination The study has been approved by the local responsible committees on human experimentation and is conducted in accordance with the ethical standards. A valuable large-scale database of speech recordings and metadata from patients with PD in France and Portugal will be constructed. Results will be disseminated in several articles in peer-reviewed journals and in conference presentations. Recommendations on how to assess speech and voice disorders in individuals with PD to monitor the progression and management of symptoms will be provided. Trial registration number NCT02753192, Pre-results.

Research on the perception of word stress suggests that speakers of languages with non-predictable or variable stress (e.g., English and Spanish) are more efficient than speakers of languages with fixed stress (e.g., French and Finnish) at distinguishing nonsense words contrasting in stress location. In addition, segmental and suprasegmental cues to word stress may also impact on the ability of speakers to perceive stress. European Portuguese (EP) is a language with variable stress and vowel reduction. Previous studies on EP have identified duration as the main cue for stress. In the present study, we investigated the perception of word stress in EP, both in nuclear (NP) and post-nuclear (PN) positions, by means of three experiments. Experiment 1 was an ABX discrimination task with stress and phoneme contrasts, without vowel reduction. Experiments 2 and 3 were sequence recall tasks with stress and phoneme contrasts, vowel reduction being added to the stress contrast only in experiment 3. Results showed significantly higher error rates in the stress contrast condition than in the phoneme contrast condition, when duration alone (PN), or duration and pitch accents (NP), are present in the stimuli (experiments 1 and 2). When vowel reduction is added, EP speakers are able to perceive stress contrasts (experiment 3). The results show that vowel reduction appears to be the most robust cue for stress in EP. In the absence of vowel quality cues, a stress “deafness” effect may emerge in a language with non-predictable stress that combines both suprasegmental and segmental information to signal word stress. These findings have implications for claims of a prosodic-based cross-linguistic perception of word stress in the absence of vowel quality, and for stress “deafness” as a consequence of a predictable stress grammar.
