Given the importance of syllables in the development of reading, spelling, and phonological awareness, information is needed about how children syllabify spoken words. To what extent is syllabification affected by knowledge of spelling, to what extent by phonology, and which phonological factors are influential? In Experiment 1, six- and seven-year-old children did not show effects of spelling on oral syllabification, performing similarly on words such as habit and rabbit. Spelling influenced the syllabification of older children and adults, with the results suggesting that knowledge of spelling must be well entrenched before it begins to affect oral syllabification. Experiment 2 revealed influences of phonological factors on syllabification that were similar across age groups. Young children, like older children and adults, showed differences between words with short and long vowels (e.g., lemon vs. demon) and words with sonorant and obstruent intervocalic consonants (e.g., melon vs. wagon).

The aim of this paper is to discuss some rhythmic differences between European and Brazilian Portuguese and their relationship to pretonic vowel reduction phenomena. After the basic facts of PE and PB are presented, we show that the issue cannot be discussed without taking into account secondary stress placement, and we proceed to present the algorithm-based approach to secondary stress in Portuguese, representative of Metrical Phonology analyses. After showing that this deterministic approach cannot adequately explain the variable position of secondary stress in both languages regarding words with an even number of pretonic syllables, we argue for the interpretation of secondary stress and therefore for the construction of rhythmic units at the PF interface, as suggested in Chomsky s Minimalist Program. We also propose, inspired by the constrain hierarchies as proposed in Optimality Theory, that such interpretation must take into account two different constraint rankings, in EP and BP. These different rankings would ultimately explain the rhythmic differences between both languages, as well as the different behavior of pretonic vowels with respect to reduction processes.

In this paper we take advantage of the segmental control afforded by full and partial Vietnamese reduplication on a constant carrier phrase to obtain acoustic evidence of assymetrical prominence relations (van der Hulst 2005), in support of a hypothesis that Vietnamese reduplications are phonetically right headed and that tone sandhi is a reduction phenomenon occurring on prosodically weak positions (Shih 2005). Acoustic parameters of syllable duration (onset, nucleus and coda), F0 range, F0 contour, vowel intensity, spectral tilt and vowel formant structure are analyzed to determine: (1) which syllable of the two (base or reduplicant) is more prominent and (2) how the tone sandhi forms differ from their full reduplicated counterparts. Comparison of full and partial reduplicant syllables in tone sandhi forms provide additional support for this analysis.

An adaptation of the standard battery of Woodcock-Johnson III Tests of Cognitive Abilities (WJ-III) for Brazilian children and youth was investigated. The sample was composed of 1094 students (54 percent girls), ages 7-17, living in Sao Paulo state (91 percent). Items from Brazilian school books as well as from the WJ-III Spanish version (Bateria-R) were added to comprehension-knowledge tests. Brazilian words were adapted to the auditory tests according to syllabic division and stressed syllables. Items were examined through IRT and age differences through analysis of variance. Results indicated the need to remove items from all WJ-III subtests with the exception of the visual learning test. Analysis of Variance indicated significant age differences (p <= 0.001) for all tests. Thus, the importance of a Brazilian adaptation for the WJ-III was confirmed.

Objective: Stimulability is the ability to produce an adequate sound under specific conditions. This study aimed to describe the stimulability of Brazilian Portuguese-speaking children with and without phonological disorders for the production of liquid sounds with the aid of visual and tactile cues. Patients and Methods: The study sample included 36 children between 5; 0 and 11; 6 years of age, 18 with phonological disorder and 18 without any speech-language disorders. Stimulability was measured for syllable imitation. The stimulability test employed includes 63 syllables with the sounds [1], [(sic)], and [(sic)], as well as seven oral vowels. If the subject was unable to imitate a sound, a visual cue was given. When necessary, a tactile cue was also given. Results: The sound [(sic)] required greater use of sensory cues. Children with phonological disorder needed a greater number of cues. Conclusion: The use of sensory cues seemed to facilitate sound stimulability, making it possible for the children with phonological disorder to accurately produce the sounds modeled.

Objective: To assess, in patients undergoing glossectomy, the influence of the palatal augmentation prosthesis on the speech intelligibility and acoustic spectrographic characteristics of the formants of oral vowels in Brazilian Portuguese, specifically the first 3 formants (F1 [/a,e,u/], F2 [/o,o,u/], and F3 [/a,o/]). Design: Speech evaluation with and without a palatal augmentation prosthesis using blinded randomized listener judgments. Setting: Tertiary referral center. Patients: Thirty-six patients (33 men and 3 women) aged 30 to 80 (mean [SD], 53.9 [10.5]) years underwent glossectomy (14, total glossectomy; 12, total glossectomy and partial mandibulectomy; 6, hemiglossectomy; and 4, subtotal glossectomy) with use of the augmentation prosthesis for at least 3 months before inclusion in the study. Main Outcome Measures: Spontaneous speech intel-ligibility (assessed by expert listeners using a 4-category scale) and spectrographic formants assessment. Results: We found a statistically significant improvement of spontaneous speech intelligibility and the average number of correctly identified syllables with the use of the prosthesis (P < .05). Statistically significant differences occurred for the F1 values of the vowels /a,e,u/; for F2 values, there was a significant difference of the vowels /o,o,u/; and for F3 values, there was a significant difference of the vowels la,61 (P < .001). Conclusions: The palatal augmentation prosthesis improved the intelligibility of spontaneous speech and syllables for patients who underwent glossectomy. It also increased the F2 and F3 values for all vowels and the F I values for the vowels /o,o,u/. This effect brought the values of many vowel formants closer to normal.

Electromagnetic articulography (EMA) was used to investigate how tongue movement characteristics (i.e., velocity, acceleration, duration, distance) change with. or indeed affect, increased rates of speech. Eight young adult males repeated /ta/ and /ka/ syllables first at a moderate rate that had been modelled at three syllables per second, and then 'as fast as possible'. Distance travelled by the tongue appeared to be the principal lingual kinematic feature manipulated by the group of speakers in producing increased syllable repetition rates, with velocity found to increase, decrease or remain unchanged. Acceleration remained unchanged, except in the case of increased velocity. One participant formed an exception in terms of manipulating distance by exhibiting marginally increased lingual velocities rather than distance changes. This preliminary study serves to direct future EMA-based studies of speech rate control as to the speech tasks that should be employed and the possible underlying anatomical and acoustic bases or constraints that could possibly influence the kinematic strategies employed to increase speech rate.

Esta pesquisa documental analisa as concepções de alfabetização, leitura e escrita subjacentes à Provinha Brasil no período 2008-2012 e o panorama em que esse programa de avaliação é produzido. Parte do referencial bakhtiniano e do conceito de alfabetização de Gontijo (2008, 2013). Ao tomar a Provinha como gênero do discurso, discute os elos precedentes dentro do contexto de produção dessa avaliação, a autoria do Programa e seus principais destinatários. Constata que a Provinha é criada como resposta às demandas de avaliação da alfabetização provenientes de organismos internacionais como o Banco Mundial e a Organização das Nações Unidas para a Educação (Unesco). A avaliação é elaborada pelo Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (Inep) como órgão que coordena as avaliações no País, em colaboração com pesquisadores de universidades e de organizações da sociedade civil, para demonstrar confiabilidade científica aliada à participação democrática no processo de produção. Seus principais destinatários são gestores de Secretarias de Educação e professores. Aos primeiros, cabe aderir ao programa de avaliação e tomar medidas administrativas para sua operacionalização nas redes. Os docentes têm o papel central de seguir as orientações do material e reorganizar sua prática em função de melhorias nos desempenhos das crianças no teste. Estas, por sua vez, são desconsideradas como sujeitos de dizeres e é legitimado um discurso homogeneizador sobre seu desenvolvimento. A partir dos testes aplicados e das matrizes de referência e seus eixos, a pesquisa analisa como a diferenciação teórica entre alfabetização e letramento se concretiza na organização das provas. A alfabetização, entendida como apropriação do sistema de escrita, é avaliada no primeiro eixo do teste principalmente como identificação de unidades menores da língua, como letras, sílabas e fonemas. As habilidades de leitura, ligadas ao letramento como concebido nos pressupostos do programa, são aferidas ora como decodificação de palavras e frases descontextualizadas, ora como apreensão de significado predeterminado do texto. A escrita somente é avaliada no ano de 2008 e por meio de itens que solicitavam codificação de palavras e frases ditadas pelo aplicador. Desse modo, a Provinha Brasil contribui para a subtração das potencialidades políticas e transformadoras do aprendizado da língua materna no País.

Resumo: Este artigo analisa a relação entre o nível de consciência fonológica, conhecimento das letra e as estratégias utilizadas para ler e escrever, em crianças de cinco anos, ensinadas em catalão. Participaram 69 crianças de três classes diferentes. Cada um dos seus professores utilizava um método diferente de ensino: analítico, sintético ou analítico-sintético. As crianças foram avaliadas no início e no final do ano letivo em: Reconhecimento de letras, segmentação palavra oral, leitura de palavras, leitura de um texto curto e um ditado. Foram realizadas análises de granulação fina em nas respostas das crianças, para identificar estratégias e padrões específicos. A análise qualitativa indica que a capacidade de segmentar uma palavra em sílabas por via oral parece ser suficiente para as crianças começarem a ler de uma forma convencional. Além disso, a consciência fonológica e o conhecimento das letras são usados em formas relativamente diferentes, dependendo do tipo de texto a ser lido. As abordagens de ensino dos professores parecem ter uma influência nos resultados das crianças.
