Abstract

 This research was aimed at clarifying the speech rate characteristics and adjustment strategies of those with profound hearing impairment in whom spoken language is the primary means of communication and who attended special education needs schools. Acoustic analysis was used to compare the speech duration for three speech rate types between people with profound hearing impairment and people with normal hearing. The results showed that those with profound hearing impairment showed lower speech rates than those with normal hearing, although there was no difference in the pause time, indicating that those with profound hearing impairment spent more time on articulation. However, there was much variation among individuals; while some participants with profound hearing impairment exhibited speech similar to those with normal hearing, others experienced difficulty in speaking quickly. The study found that across different speech rates, comparison of speech time and pause time revealed that both those with normal hearing and those with profound hearing impairment used increases and decreases in intra-sentence and inter-sentence pause times as a strategy to adjust the speed of their speech.
