El presente trabajo indaga en aspectos de la gramatica y del discurso narrativo que son problemáticos para los niños con Trastorno Específico del Lenguaje (TEL). Participaron 60 niños hablantes del español: 20 niños con TEL cuyo promedio de edad fue 6.6 y dos grupos controles: 20 niños con desarrollo típico equiparados en edad cronológica y 20 niños con desarrollo típico igualados por Longitud Media del Enunciad (LME). Cada niño escuchó tres cuentos que recontó y luego respondió preguntas sobre los relatos. Las narraciones se analizaron según aspectos gramaticales (complejidad y gramaticalidad de las oraciones) y discursivos (estructura y relaciones semánticas). Se corrigieron las respuestas infantiles distinguiendo respuestas literales e inferenciales. Los resultados muestran que el grupo con TEL en gramaticalidad de las oraciones y en comprensión narrativa evidencia un comportamiento semejante al de los controles equiparados por LME. No obstante, en complejidad de las oraciones y en producción narrativa sus coloma, mendoza y carballo: desempeño 68 desempeños fueron similares a ambos controles. En consecuencia, los núcleos problemáticos de los niños con TEL más evidentes en gramática es la agramaticalidad de las oraciones y en narración la comprensión narrativa.Palabras clave: Trastorno específico del lenguaje, Narración, Gramática.
AbstractThis study focuses on the grammatical and narrative performance of children diagnosed with specific language impairment (SLI). Sixty native Spanish-speaking children were grouped as follows: SLI group (n=20, mean age=6.6 years), chronological-age control group (typical language development children n=20), and MLU control group (typical language development children paired by Mean Length Utterance, n=20). All children were asked to listen and retell three narratives, as well as to answer narrative-related questions. Retold stories were analyzed considering grammatical features (complexity and grammaticality in sentences), and discursive features (structure and semantic relations). Results show that SLI group performs similarly to MLU control group when observing sentence grammaticality and narrative comprehension. When analyzing grammatical complexity and narrativevproduction, SLI performance is statistically similar to both control groups. Results suggest that SLI children's ungrammatical sentences and narrative comprehension are the most troublesome domains in Grammar and Discourse, respectively.
The aim of this study was to obtain acoustic correlates to vocal quality of a group of men and women with and without voice disorders, based on evaluations of a group of judges experienced in the field of vocal rehabilitation. In male subjects, perceptual evaluation of normal, hoarse and rough voice qualities was related to the following acoustic features: frequency perturbation measures (JITA, RAP, and SPPQ), amplitude perturbation (SAPQ and VAM), soft phonation index (SPI) and fundamental frequency tremor intensity (FTRI). While these measures presented normal values for normal voice, hoarseness showed some deviations in perturbation frequency variables and very high SPI values, while rough voice showed deviations in all the measures. Qualities of female voices were perceived as normal, breathy and hoarse, but the acoustic correlates of these qualities were less conclusive.
The objective of this study was to estimate the agreement and reliability of voice evaluation by a group of expert listeners using the central portion of a sustained vowel and a fragment of connected speech as voice samples. Ratings were made using Wilson's Buffalo III Voice Screening Profile. Analysis showed that intraindividual listeners' agreement presented variability in the evaluation of both voice samples. In the evaluation of the central portion of the sustained vowel, interindividual listener agreement was moderate for breathiness, hyponasal resonance, and overall voice rating; in connected speech, agreement was moderate for most voice qualities (breathy, rough, high/low pitch, and hyponasal resonance). Finally, Wilson's Buffalo III Voice Screening Profile presented good reliability values for both voice samples, with overall voice rating achieving higher values (.90) than any other voice-quality variable.
A crosslinguistic study is underway concerning children's protracted phonological development (i.e. speech sound disorders). The current article reports pilot Spanish data for this study from two 4-year-old boys with protracted phonological development. The purposes of the pilot study were to: (1) develop and evaluate a word list for elicitation that could be used across Spanish dialects and that sufficiently sampled Spanish word lengths, stress patterns, word shapes and phonemes; and (2) to derive hypotheses for the larger study, based on patterns found in these children's speech, and a review of the literature. The two speakers showed some developmental patterns reported for other languages (e.g. constraints on production of liquids and word-initial consonants in unstressed syllables) but also patterns that may reflect Spanish phonological inventories, allophony and frequencies. These data helped consolidate the Spanish word list for elicitation and led to questions for the ongoing study concerning word structure, multisyllabic words, liquids, fricatives and vowel sequences.
