Objective To describe the speech pattern of patients with hereditary Spastic Paraplegia type 4 (SPG4) and correlated it with their clinical data. Methods Cross-sectional study was carried out in two university hospitals in Brazil. Two groups participated in the study: the case group (n = 28) with a confirmed genetic diagnosis for SPG4 and a contro...

In order to correlate reading proficiency and prosodic aspects, we characterized the reading aloud of readers at different levels of education regarding the acoustic behavior of target phrases under the scope of basic emotions: joy, anger and sadness, as well as in a neutral way. We seek to show how these different reader profiles process pragmatic...

Basal ganglia participate in neural networks that control voluntary body movements, including speech. Diseases that affect the function of these structures can generate abnormal hypokinetic or hyperkinetic movements, influencing speech motor control. How does prosodic temporal organization vary in dysarthria due to Parkinson’s disease (PD), Hunting...

This study investigates coarticulatory effects caused by the following consonant – either a stop or a fricative – on the duration of the oral and the nasalized portion of the nasal vowel and the nasal murmur in sequences within Portuguese words like tensa [ˈtẽsɐ] ‘tense’ versus tenta [ˈtẽtɐ] ‘(s/he) tries.’ The results replicate previous observatio...

Background/aims: Studies of people with dyslexia have pointed to the ability to perceive the amplitude envelope rise time ("beat" perception) as a possible cause of phonological processing (PhP) difficulties in this population. However, there are very few studies about the relationships between such skills in the non-dyslexic school population. M...

The N1-P2 complex of the auditory event-related potential (ERP) has been used to examine neural activity associated with speech sound perception. Since it is thought to reflect multiple generator processes, its functional significance is difficult to infer. In the present study, a temporospatial principal component analysis (PCA) was used to decomp...

Studies exploring the mismatch negativity (MMN) response to speech sounds have identified neural activity associated with processing of phonologically distinctive information and language-specific perceptual categorisation. Yet little attention has been given to a basic fact of phonology, namely, that not all phoneme distinctions in a language are...

An important issue regarding developmental changes in cue weighting is whether children weight the dynamic cue of vowel formant transitions relatively more than do adults, whereas adults depend more on the static cue of the fricative noise level. We investigated this issue in Brazilian Portuguese. Additionally, we inserted the segment to be classif...

Objective: To verify the internal reliability of the DIP protocol in Brazilian subjects with Parkinson’s disease (PD). Background: The dysarthria can be defined as a speech alteration, it is one of the most evident signs in this population with PD. Often, the quality of life of people with PD is impaired by not being able to communicate effectively...

Objective: To assess the vowel lengthening in Parkinson’s Disease (PD)1 and the alignment of the rising prenuclear accent (RPA) in Brazilian Portuguese (BP). BP speakers often realized it as an f0 rise in the stressed syllable of a phonological word2 . Background: RPA peak reportedly occurs in stressed or poststressed syllable vocoids. The alignmen...

Resumo: Este artigo trata das pistas auditivas utilizadas para a distinção de ponto de articulação no português brasileiro (PB). Na primeira parte, descrevemos as propriedades acústicas das fricativas [ʃ] e [s] e das plosivas [b] e [d] seguidas da vogal [a]. Foram analisadas amostras de fala de sete falantes nativos de PB registrados em Belo Horizo...

We investigated whether the mean duration of syllables in utterances of different length in Brazilian Portuguese conform to Menzerath–Altmann’s law. Furthermore, by analysing the same spoken material of twenty recorded speakers, we tested for individual differences in the parameters used to formalise the law. The log-transform of the syllable durat...

According to the neural adaptation model of the mismatch negativity (MMN), the sensitivity of this event-related response to both acoustic and categorical information in speech sounds can be accounted for by assuming that (a) the degree of overlapping between neural representations of two sounds depends on both the acoustic difference between them...

Cross-linguistic studies aim at determining the similarities and differences in speech production by uncovering linguistic adaptations to specific constraints and environments. In the field of motor speech disorders, such a cross-language approach could be of great interest to understand not only the deficits of speech production that are induced b...

Cross-linguistic typological observations and theoretical models in phonology suggest that certain speech sound distinctions are more complex then others. One such example is the opposition between mid-high and mid-low vowels, usually thought to be more complex than the opposition between high and mid vowels. The present study provides experimental...

Intrinsic fundamental frequency (IF0) refers to a systematic difference in f0 between vowels of different heights in a similar phonetic context: high vowels tend to have higher f0 than lower vowels. Various hypotheses as to the cause of IF0 have been raised, differing mainly on the nature they attribute to the phenomenon: whether it is passive (aut...

A percepcao dos sons da fala envolve operacoes de categorizacao em que os eventos acusticos que compoem o fluxo sonoro da fala sao agrupados em classes de equivalencia, ou seja, categorias cujos membros sao tratados pelos falantes como funcionalmente equivalentes. Diversas linhas de evidencia indicam efeitos relacionados a essas categorias sobre a...

Purpose (a) to determine whether an individual’s behavior, in the perception of consonants in different noise conditions, is directly related to how these sounds are represented in the mind, (b) to determine whether there is a relationship between phonological and perceptual similarity. Methods The study used a non-probability sample based on typi...

This study aims to reassess the findings of Moraes & Wetzels (1992) on the duration of distinctive nasal vowels of BP by including more vowels and contexts. According to the hypothesis, a longer duration of nasal vowel is a manifestation, at the level of phonetic implementation, of an underlying bimoraic representation which cause nasal vowels to b...

The relationship between speech perception skills and auditory temporal resolution in children with no language or hearing impairment was investigated in a correlational study. The influence of age and sex on these skills was also estimated. From a sample of 80 children, 37 were selected between 7-11 years. No statistical correlation resulted betwe...

The purpose of this article is to survey the available studies on the national and international speech perception perspective of language development. Thus, we dealt with the phonological development of children with focus on perception, as well as studies related to the categorization of speech sounds, including categorical perception and the dev...

We present a comprehensive bibliography on nasal vowels in Portuguese. Articles, books and book chapters, theses and dissertations were included, as well as abstracts featured in Brazil and in Portugal. Abstracts presented in local or regional meetings were excluded. There are 103 references on the subject, published between 1903 and 2012. To the b...

In Brazilian Portuguese, minimal pairs are attested for the contrast between open- and close-mid vowels in stressed syllables. However, there are cases in which these two categories show free variation in this same context without semantic consequences. With the aim of verifying whether this phenomenon is reflected in representations stored in long...

This study was designed to provide an index of translation quality, by means of which several translations of the same text could be compared for research purposes in Translation Studies (TS). It is part of a more comprehensive research on the relationship between some of the translator's cognitive characteristics and various features of the transl...

artigo faz revisão de resultados de algumas pesquisas psicológicas sobre juízo moral e processos de tomada de decisão (TD). Juízos morais são formulados inicialmente de forma automática, implícita, a partir de reações emocionais. Apenas em etapa ulterior do processamento são racionalmente elaborados. Tanto pacientes quanto profissionais têm dificul...

An analysis of pause distribution for 12 subjects on a controlled copying task suggests that pause-based measures used to assess writing processes should reflect individual differences in typing.

This paper presents a task for phoneme discrimination as part of a more comprehensive set of tasks for psycholinguistic assessment of language currently under development (TAL-UFMG). The task consists of 40 pairs of monosyllabic nonwords, from which 20 pairs are made of two copies of the same syllable and 20 pairs differ in relation to one single f...

A descriptive analysis of translations, such as that outlined in Toury (1995), is said to involve the establishment of translation relationships within coupled pairs of replacing and replaced textual segments. But how is one to assess the significance of particular kinds of segment for the entire text under analysis? The present article tackles thi...

A memória de trabalho pode ser concebida em termos de sistemas de armazenamento ou por meio de modelos processuais ou dinâmicos. Nós adaptamos, para uso com a população brasileira, uma bateria de testes baseada em um modelo que divide a memória de trabalho em três aspectos: eficiência ou velocidade de processamento, armazenamento temporário e coord...

We critique five points that impede the target article's far-reaching efforts toward formulating a neurobiological theory of language. Neurolinguistics amounts to no more than neurology in linguistics in this account, because it assumes “perceptual representational isomorphism,” processing autonomy and “meaning,” thereby aiming primarily at ju...

The first part of the article touches upon metatheoretical constraints to translator¿s qualities research represented by the «methodological infancy» of Translation Studies (TS), the role that professional self-esteem of translators plays in TS research, and the lack of importance attributed to a pure science of translation. The main part is devote...
