Perceptual Judgments of Resonance, Nasal Airflow, Understandability, and Acceptability in Speakers with Cleft Palate: Ordinal versus Visual Analogue Scaling

Abstract

Perceptual judgments of nasal resonance, nasal airflow, understandability, and acceptability were similar using VAS and ordinal scaling, indicating that both scaling methods were appropriate for measuring the cleft speech parameters. VAS, however, may offer statistical advantages, and there is a growing body of evidence advocating its use for the measurement of prothetic speech parameters.

Ampliação e validação do protocolo de avaliação miofuncional orofacial para indivíduos com fissura labiopalatina

“…It is believed that the use of this material can also turn it possible the training of students for the assessment process of these patients, as well as it will help less experienced professionals to use it, and will also permit the standardization of inter center results. However, it is worth highlighting that there is the need of systematic training of the assessors for the application of the elaborated protocol, as suggested by some authors (5,17) .…”

Escala de Borg: um novo método para avaliação da hipernasalidade de fala

“…Several researchers defend the theory that the nasality is a sensation mentally processed as a prothetic dimension, that is, it differs in terms of change in degrees of quantity (1,(3)(4)(5)(6) . Thus, the use of appropriate rating scales for the nasality characteristics can improve the reliability of the auditory-perceptual assessment of this symptom, turning it less susceptible to errors and consequently reducing the variations of different perceptual judgments (1,3,6,7) .…”

“…Additionally, the obtained ratings are relatively easy to be compared among different scales and listeners (9,11) . By using the ordinal scale, the listener assigns a score to the evaluated symptom in a linear scale, indicating its degree of severity at a nominal classification order, where the lowest category represents the absence of symptom and the highest, the symptom maximum degree (7,8) . However, the ordinal scale separates the different categories of speech symptoms without quantifying the magnitude of the difference between each category.…”

“…In the ratio-based scales, the listeners freely assign a number that represents the sensorial magnitude of the assessed stimulus. Ratio scale examples are the Direct Magnitude Scale and the Analogical Visual Scale (1,7) .…”

Elaboração de um instrumento para predizer o fechamento velofaríngeo com base nas características de fala e sua correspondência com as dimensões do orifício velofaríngeo

“…A transcrição fonética, embora frequentemente citada na literatura internacional (GOOCH et al, 2001;LOHMANDER et al, 2009;SELL et al, 2009;KLINTO et al, 2011;LOHMANDER et al, 2011;CHAPMAN et al, 2016), não foi empregada no presente estudo. A despeito do fato de favorecer a classificação de acordo com a natureza do erro em relação ao ponto articulatório (JOHN et al, 2006), há controvérsias em relação à confiabilidade e concordância dos resultados interavaliadores (CHAPMAN et al, 2016 A hipernasalidade, por sua vez, foi classificada utilizando escala ordinal de 4 pontos, por se tratar do método perceptivo mais utilizado, até então, na prática clínica para a avaliação dos sintomas de fala da fissura palatina (HENNINGSSON et al,2008;CASTICK et al,2017).…”
