چکیده انگلیسی
Mean fundamental frequency (F0) values are often used in research on vocal load. In this study, we examine how the mean F0 differs when evaluated through pronouncing a standard phrase as compared to the mean F0 obtained in a real work/play environment. We also examine how the F0 values change throughout the day. The study was performed in a preschool, nine adult female preschool teachers and 11 children participated. The participants wore a digital recorder equipped with an accelerometer, which was attached to the neck. In the study, the participant first pronounced a standard phrase in a controlled environment; thereafter, the voice was recorded in the environment where both children and adults normally reside throughout the day, denoted by the work/play environment. For each participant, the procedure was repeated four times throughout the day. Analyses showed that the F0 values of the children's and adult's voices were significantly higher when recorded in the work/play environment as compared to the controlled environment. The average difference was 36Â Hz for adults and 24Â Hz for children. Previous studies have shown an increase of F0 over the day for teachers. In this study, an increase between morning and afternoon values was found amounting to 8Â Hz for adults and 24Â Hz for children. For the child population, this increase was statistically significant. However, the total changes over the day revealed a somewhat more complex scheme, with an increase of F0 in the morning, a decrease during lunch, and finally an increase in the afternoon. This pattern was verified statistically for the joint child-adult population.
