Abstract
Word intelligibility scores of 21 listeners were used to test the hypothesis that speech intelligibility will vary systematically across speakers and fundamental frequency of electrolarynx vibration.
Twenty-one listeners transcribed audio recorded lists of CVC utterances produced with an electrolarynx by 3 speakers at each of five fundamental frequencies.
Comparative analysis of scores across frequencies and speakers were discussed in terms of:
a) source transmission characteristics of "electrolaryngeal" speech, b) implications for diagnosis/therapeusis of alaryngeal speakers.
Results indicated that intelligibility scores were significantly different between speakers and between frequencies within speakers. Maximum intelligibility scores were more highly correlated with certain frequencies for certain speakers. Results indicated that the relation of maximum intelligibility scores and fundamental frequency of vibration is speaker dependent.
Additional post hoc information about phoneme error type substitutions, sex recognition, and quality judgments of acceptability of the speakers was related to intelligibility differences.
