The aim of this study was to confirm previously reported differences in the durations of phones and words spoken by normal-hearing and hearing-impaired individuals. For this purpose, utterances of 400 isolated Finnish words were recorded from eight hearing-impaired and four normal-hearing adult subjects. The utterances were manually labeled by two phoneticians and collected into a searchable speech database. Durations of phones and words were measured for each subject. The mean durations of both words (N=4800) and phones (N=27478) were longer for the hearing-impaired subject group. The two groups differed significantly regarding the durations of the words and phones. The results are important regarding both speech recognition technology and clinical methods.
