Acoustic Attributes of Mandarin Retroflex Vowel “ɚ” Produced by Prelingually Deaf Children with Cochlear Implants

Yu-xin Lin, Jue Yu, Yiyuan Liao


The present paper examined the acoustic attributes of Mandarin retroflex vowel “ɚ” articulated by prelingually deaf children with cochlear implants (CIs). The main purpose is to obtain a comprehensive understanding about how CI children acquire this target vowel in different lexical positions. The results showed that, (1) CI children could averagely produce the retroflex vowel with the mastery level accuracy, (above 75% accuracy), but made more articulatory errors than the NH counterparts; (2) allocated different duration to the target vowel according to specific lexical position as the NH children did, but averagely tended to produce the vowel with longer duration, especially in the medial location; (3) showed the formant pattern of the target vowel with significant difference from the NH group, specifically in the F3, which determined the retroflex color; (4) only the length of CI device use was found to be a significant contributor for accuracy performance of CI children but no systematic correlation was found between the acoustic attributes and the use of cochlear implant devices.
