BERTI, Larissa Cristina; PAGLIUSO, Alessandra and LACAVA, Francine. Speech evaluation instrument for acoustical analysis based on linguistic criteria. Rev. soc. bras. fonoaudiol. [online]. 2009, vol.14, n.3, pp. 305-314. ISSN 1982-0232. http://dx.doi.org/10.1590/S1516-80342009000300005.
PURPOSE: To elaborate a speech evaluation instrument for children contemplating all consonant sounds of Brazilian Portuguese, in order to make possible the use of an instrumental methodology. METHODS: The selection of words was based on pre-defined linguistic criteria of the Brazilian Portuguese, searched on the CETENFolha Database. The linguistic criteria searched were: grammar class, number of syllables, stress and syllabic patterns. RESULTS: Based on the linguistic criteria, the speech evaluation instrument comprised 96 words that contemplated at least three occurrences of all consonant phonemes of Brazilian Portuguese accompanying the vowels /i, a, u/ in stressed position. Among the words selected for the instrument, there was a prevalence of dissyllable nouns with the penultimate syllable stressed. Moreover, 57 words began with a simple syllabic pattern, and 39 words involved the production of a complex syllabic pattern. CONCLUSION: The present study not only provided linguistic criteria for the elaboration of speech production and/or perception evaluation instruments, but also made available a speech evaluation instrument for instrumental analysis in Speech-Language Pathology.
