Background:
The speaking voice profile serves to capture individual parameters of the speaking voice. For this purpose, the sound pressure and frequency while counting are measured in 4 different intensity levels: softest speaking voice (I); conversational voice (II); classroom voice (III); and shouting voice (IV).
Material and methods:
As part of a large population-based cohort, complete speaking voice profiles were obtained of more than 5,000 participants aged between 6 and 80 years.
Results:
The data generated standard values for the speaking voice of children and adults. The measured frequencies for the female voice pitch are about half an octave lower than previously described in the literature. There are significant changes in the female voice between the ages of 20 and 30 years.
Conclusion:
The changes in the female voice in young adulthood suggest a change in the role model.
