This work reviews the advancements in the non-conventional analysis of speech signals,
particularly from an AM-FM analysis point of view. The benefits of such an analysis, as …

The vocal tract shape is three-dimensionally complex. For accurate acoustic analysis, a finite-
difference time-domain method was introduced in the present study. By this method, transfer …

(1999)] to measure the temporal changes in the vocal tract area function during a short
utterance/aiueo/in Japanese. A time series of head-neck volumes was obtained after 640 …

In both the voice and musical wind instruments, a valve (vocal folds, lips, or reed) lies
between an upstream and downstream duct: trachea and vocal tract for the voice; vocal tract …

In humans, there are four basic laryngeal functions: airway protection, which is particularly
important during deglutition; effort closure for fixation of the trunk while moving the upper …

The acoustic effects of the laryngeal cavity on the vocal tract resonance were investigated by
using vocal tract area functions for the five Japanese vowels obtained from an adult male …

The use of acoustic–prosodic features related to F0, duration and voice quality is proposed
and evaluated for automatic extraction of paralinguistic information (intentions, attitudes, and …

The piriform fossae are the 2 pear-shaped cavities lateral to the laryngeal vestibule at the
lower end of the vocal tract. They act acoustically as side-branches to the main tract …

The vocal tract shape is crucial to voice production. Its lower part seems particularly relevant
for voice timbre. This study analyzes the detailed morphology of parts of the epilaryngeal …

Self-recognition, being indispensable for successful social communication, has become a
major focus in current social neuroscience. The physical aspects of the self are most …
