“…In the present study, by correlating the nasalance scores with the auditory perceptual judgments, the results showed that, although statistically significant, the correlation was low (between 0.31 and 0.37). These results corroborate with previous findings 16 which also found a low correlation between the two variables, differing, however, with studies that found high 9,11-13 or moderate 14,15 correlations between speech nasality and the nasalance scores.…”

“…Regarding the nasalance scores, it is stressed that the studies that found a high 9,11,13 or moderate 14,15 correlation between the nasalance and nasality used texts such as speech stimulus or set of phrases 9 . Some authors 34 investigated the minimum extent that the speech stimuli might have to keep the same result of nasalance of the original stimulus is composed of adults and children with varying degrees of hypernasality (ranging from mild to severe), unlike the present study which was limited to children, predominantly with mild hypernasality values.…”

“…With regard to the correlation between the measures of nasalance and the perceptual auditory judgment of nasality, results obtained in previous studies showed that this correspondence is not absolute, nor linear. While some of these studies reported high correlation between these two aspects with the use of oral stimulus 9,11-13 other reported moderate correlations 14,15 and even lower correlations 16 . This wide variation in results has been attributed to methodological differences to correct the cleft.…”

“…This result may be explained by the type of scale used to classify hypernasality. As in most studies in the literature, the present study used an ordinal scale, which has been the most widely used both in research and in clinical practice (27,28) . However, due to the psychophysical nature of nasality, high agreement among different raters have been difficult to achieve using this method (29) .…”

RESUMO Objetivo Investigar a influência do tipo de amostra de fala, conversa espontânea ou repetição de sentenças, sobre o índice de concordância intra e interavaliadores obtido na classificação perceptiva da hipernasalidade. Métodos Foram selecionadas e editadas 120 amostras de fala gravadas em áudio (60 contendo trechos de conversa espontânea e 60 contendo repetição de sentenças) de indivíduos com fissura de palato±lábio reparada, de ambos os sexos, com idade entre 6 e 52 anos (média=21±10 anos). Três fonoaudiólogas experientes, utilizando seus critérios internos, classificaram a hipernasalidade em escala de 4 pontos: 1=ausente, 2=leve, 3=moderada e 4=grave, primeiramente na amostra de conversa espontânea e, 30 dias depois, na repetição de sentenças. Os índices de concordância intra e interavaliadores foram estabelecidos para ambos os tipos de amostra de fala e comparados entre si por meio do Teste Z com nível de significância de 5%. Resultados A comparação dos índices de concordância intra-avaliadores entre os dois tipos de amostra de fala mostrou aumento dos coeficientes obtidos na análise da repetição de sentenças em relação aos obtidos na conversa espontânea, já a comparação entre os índices de concordância interavaliadores não mostrou diferença significante entre as três avaliadoras para os dois tipos de amostras de fala. Conclusão A repetição de sentenças favoreceu a confiabilidade do julgamento perceptivo da hipernasalidade de um mesmo avaliador, visto que a concordância intra-avaliadores na análise desta amostra de fala foi maior. No entanto, o tipo de amostra de fala não influenciou a concordância entre diferentes avaliadores.

In patients with a repaired cleft palate, nasality is typically diagnosed by speech language pathologists. In addition, there are various instruments to objectively diagnose nasalance. To explore the potential of nasalance measurements after cleft palate repair by NasalView®, we correlated perceptual nasality and instrumentally measured nasalance of eight speech items and determined the relationship between sensitivity and specificity of the nasalance measures by receiver-operating characteristics (ROC) analyses and AUC (area under the curve) computation for each single test item and specific item groups. We recruited patients with a primarily repaired cleft palate receiving speech therapy during follow-up. During a single day visit, perceptive and instrumental assessments were obtained in 36 patients and analyzed. The individual perceptual nasality was assigned to one of four categories; the corresponding instrumental nasalance measures for the eight specific speech items were expressed on a metric scale (1–100). With reference to the perceptual diagnoses, we observed 3 nasal and one oral test item with high sensitivity. However, the specificity of the nasality indicating measures was rather low. The four best speech items with the highest sensitivity provided scores ranging from 96.43 to 100%, while the averaged sensitivity of all eight items was below 90%. We conclude that perceptive evaluation of nasality remains state of the art. For clinical follow-up, instrumental nasalance assessment can objectively document subtle changes by analysis of four speech items only. Further studies are warranted to determine the applicability of instrumental nasalance measures in the clinical routine, using discriminative items only.
