Zusammenfassung
Speaker age is a speaker characteristic which is always present
in speech. Previous studies have found numerous acoustic features which
correlate with speaker age. However, few attempts have been made to
establish their relative importance. This study automatically extracted
161 acoustic features from six words produced by 527 speakers of both
genders, and used normalised means to directly compare the features.
Segment duration and sound pressure level (SPL) range were identified
as the most important acoustic correlates of speaker age.
