Use of formant centralization ratio for vowel impairment detection in normal hearing and different degrees of hearing impairment.

CONCLUSIONS: The findings of this study showed that FCR was a more sensitive acoustic parameter than F2i/F2u ratio and VSA to distinguish speech of the HL groups from that of the normal group. Thus, FCR is considered to be applicable as an early objective measure of impaired vowel articulation in HL speakers.
