ABSTRACT
Objectives
In a clinical setting, a ‘trained ear’ is the essentials for speech–language pathologists (SLPs) because most SLPs rely on the auditory - perceptual method during assessment and treatment for speech difficulties. However, transcribing distortion errors using only auditory-perceptual judgement is a difficult task. This study investigated the auditory– perceptual ability in terms of distortion errors for pre and present SLPs.
Methods
Sixty pre and present SLPs completed a survey, then performed a perceptual judgement task which was manufactured by electropalatography (EPG). The task consisted of 30 questions, including distorted (dentalized, palatalized, lateralized) and normal speech samples of Korean fricative /s/ with different types of vowels (/ɑ/, /u/) and lengths (1-syllabled, 2- syllabled, sentence).
Results
There was no significant difference in the distortion task among three groups. All participants had the highest score in “dentalization”, the lowest in “lateralization”, and all distortion types were perceived better in the /u/ context than /ɑ/. Also, SLPs tended to judge “lateralization” errors as “normal articulation” and many of the participants perceived “palatalization” as “lateralization”.
Conclusion
The results of this study indicated that active auditory training for SLPs is necessary to improve auditory perceptual ability, and suggests that EPG could be a useful instrument for the auditory training program.
