A Phonetic Complexity-Based Approach for Intelligibility and Articulatory Precision Testing: A Preliminary Study on Talkers With Amyotrophic Lateral Sclerosis

Abstract

Considering phonetic complexity for dysarthria tests could result in more sensitive assessments for detecting and monitoring dysarthria progression.

Properties of Relative Timing and Phonetic Complexity in Adults with Dysarthria Secondary to Amyotrophic Lateral Sclerosis

“…Kuruvilla-Dugdale et al [25] measured differences in phonetic complexity related to dysarthria secondary to ALS. Based on a modified version of Kent's rubric for evaluating phonetic complexity [22], two lists of words were created, one of which contained "simple" words (with low complexity scores) and one containing "complex" words (with high complexity scores).…”

“…They found that whether a word was "simple" or "complex" had a significant effect on the intelligibility judgments of the listeners. Kuruvilla-Dugdale et al [25] suggested an effect of phonetic complexity on the speech of individuals with dysarthria.…”

“…The phonetic complexity for each of the relative timing ratios was analyzed using the framework developed by Kent [22], and adapted by Kuruvilla-Dugdale et al [25] to include vowels and consonant clusters (Table 2). The aim of this analysis was to perform a preliminary examination of the influence of phonetic complexity on relative timing.…”

Penggunaan Non Speech Oral Motor Treatment (NSOMT) Sebagai Pendekatan Intervensi Gangguan Bunyi Bicara

“…Fonem /l/ memiliki Point of Articulation (POA) lingual alveolar, artinya pembentukan fonem ini memerlukan pergerakan lidah ke arah gusi gigi atas. Metode tersebut merupakan bagian dari pendekatan berbasis motorik (Kuruvilla-Dugdale et al, 2018;Preston et al, 2019). Hal tersebut diduga memiliki linieritas dengan alasan penggunaan NSOMT ketika menangani gangguan bunyi bicara.…”

“…Salah satu tantangan dan hambatan pelayanan klinis adalah keterbatasan sumber literatur dan penerapan EBP dalam konteks klinis. Penerapan EBP dalam penanganan gangguan bunyi bicara merupakan prasyarat yang perlu dilakukan meskipun memiliki tantangan dan hambatan dalam penerapannya (Diepeveen et al, 2020;Kuruvilla-Dugdale et al, 2018;Preston et al, 2019).…”
