The
study was made because there is a huge need among choir leaders and singing
teachers to differentiate between development of voice and pathology. Vocalquality and speech develop essentially in childhood and adolescence of boys andgirls.
The understanding of how the pediatric voice develops and changes over
time is crucial for the evaluation of children with voice disorders and their
response to treatment. In children choirs the measurements support the singing
teachers in differentiating between development of voice and pathology (e.g.
allergy and infections). This review is based on the study of Mette Pedersen
from 2008 “Normal Development of Voice in Children: Advances in Evidence-Based
Standards“.
Frequency
of the speaking voice: The fundamental
frequency of voice changes with age from childhood through puberty to adulthood
related to the hormonal development. The frequency of the normal speaking voice
in children ranges from 250-400 Hz, adult females tend to speak around 200 Hz on
average, and adult males around 150 Hz. Read more>>>>>>>>
