5th International Conference on Spoken Language Processing
The process of the development of fine motor speech skills co-occurs with the maturation of the vocal apparatus. This brief study presents some acoustic phonetic characteristics of the speech of twenty pre-adolescent (6-, 8- and 10-year-olds) boys and girls. The speech data were elicited via a picture-naming task. Both age and sex differences in the acoustic phonetic characteristics of selected vowels and consonants are examined. The acoustic phonetic characteristics that were investigated included formant frequency values and coarticulation (or gestural overlap) patterns. Age, sex and age-by-sex differences for the acoustic phonetic characteristics are presented and discussed for the data with reference to speech development and the sexual dimorphism of the vocal apparatus.
