Fundamental frequency characteristics of mild and moderate intellectual disabled adults’ speech

The purpose of this study was to analyse the fundamental frequency characteristics of mild and moderate intellectual disabled adults’ speech. Altogether 10 women (5 participants in the intellectual disabled group and 5 control adults, aged between 20 and 62 years) participated in the research. The speech samples consisted of spontaneous and read speech. The mean fundamental frequency and f 0 maximum/f 0 minimum ratio were analysed in the declarative utterances. The results were compared between the group of the intellectual disabled adults and the age- and gender-matched control group of typical speakers. The findings of this experiment were the following: 1. The mean fundamental frequency was higher in read speech than in spontaneous speech in both the intellectual disabled adults’ and the control adults’ speech. 2. The mean fundamental frequency was higher in the intellectual disabled adults’ than in the control adults’ speech, in accordance with earlier studies of the international literature.
