Purposes: Speech acceptability means the subjective judgement of listeners regarding the naturalness and normality of thespeech. The purpose of this study was to determine the predicting variables for speech acceptabilities of children withcochlear implants. Methods: Twenty seven children with CI participated. They had profound pre-lingual hearing loss withoutany additional disabilities. The mean of chronological ages was 8;9, and mean of age of implantation was 2;11. Speechsamples of reading and spontaneous speech were recorded separately. Twenty college students who were not familiar to thespeech of deaf children evaluated the speech acceptabilities using visual analog scale. 1 segmental (articulation) and 6suprasegmental features (pitch, loudness, quality, resonance, intonation, and speaking rate) of speech were perceptuallyevaluated by 3 SLPs. Correlation and multiple regression analysis were performed to evaluate the predicting variables . Results: The means of speech acceptability for reading and spontaneous speech were 73.47 and 71.96, respectively. Speechacceptability of reading was predicated by the severity of intonation and articulation. Speech acceptability of spontaneousspeech was predicated by the severity of intonation and loudness. Discussion and conclusion: Severity of intonation was themost effective variable to predict the speech acceptabilities of both reading and spontaneous speech. A further study would benecessary to generalize the result and to apply this result to intervention in clinical settings.
