A fundamental frequency investigation of children ages 6-10 years old.
The fundamental frequency characteristics of 30 children between the ages of 6 and 10 years were investigated in a variety of speech tasks. The results indicated that average fundamental frequency across tasks for the boys is approximately 262 Hz, and for girls approximately 281 Hz. Statistical analysis indicated that there was no significant difference in the fundamental frequency of boys and girls in this age range. High vowels were found to have higher fundamental frequency values than low vowels. Sustained vowels had higher fundamental frequency values than either spontaneous speech or reading for both groups of speakers. The results of this investigation are discussed in terms of maturational processes, and in comparison to corresponding adult information.
