Glottal-pulse rate (GPR) and vocal-tract length (VTL) are related to the size, sex, and age of
the speaker but it is not clear how the two factors combine to influence our perception of …

There is information in speech sounds about the length of the vocal tract; specifically, as a
child grows, the resonators in the vocal tract grow and the formant frequencies of the vowels …

A new method for source information extraction is proposed. The aim of the method is to
provide optimal source information for the very high quality speech manipulation system …

The length of the vocal tract is correlated with speaker size and, so, speech sounds have
information about the size of the speaker in a form that is interpretable by the listener. A wide …

Portions of this work were presented in “The role of input speaker upon judgements of
speaker sex and age,” British Society of Audiology, Cambridge, UK, 2006,“Role of glottal …

The formant-pattern present in a given vowel sound will be determined by the vocal-tract
length (VTL) of the speaker as well as by phoneme-specific information. Although human …

This chapter is about the perception of the sounds that animals use to communicate at a
distance and the information that these sounds convey about the animal as a source …

The perception of apparent-talker height is mostly determined by the fundamental frequency
(f0) and spectral characteristics of a voice. Although it is traditionally thought that spectral …

Spectral information in speech sounds varies as a function of linguistic content, as well as
the vocal-tract length (VTL) of the speaker. It is usually considered that human listeners rely …

The vocal tract length of a speaker is the primary determinant of the range of formant
frequencies (FFs) produced by that speaker. Listeners have demonstrated sensitivity to the …
