Interpopulation differences in acoustic characteristics of phonation.
The purpose of this study was to investigate possible differences in acoustic characteristics of phonation between populations of European and African origin. The subjects were 33 adult males divided in two groups. Group One consisted of 17 men of African origin, and Group Two included 16 men of European origin. All subjects were without vocal pathology at the time of the investigation, smokers...
متن کاملAcoustic and Egg Analysis of Pressed Phonation
Pressed phonation ("rikimi" in Japanese) is a voice quality that carries important paralinguistic information of expressivity in the emotional or attitudinal states of the speaker. Analysis of pressed voice samples extracted from natural conversational speech firstly shows that irregularity in periodicity (such as in vocal fry and harsh voices) is a common but not a strictly determinant feature...
متن کاملMaximum phonation time in pre-school children.
UNLABELLED Past studies on the maximum phonation time (MPT) in children have shown different results in duration. This factor may reflect the neuromuscular and aerodynamic control of phonation in patients; such control might be used as an indicator of other evaluation methods on a qualitative and quantitative basis. AIM To verify measures of MPT and voice acoustic characteristics in 23 childr...
متن کاملA novel instrument to measure acoustic resonances of the vocal tract during phonation
Acoustic resonances of the vocal tract give rise to formants (broad bands of acoustic power) in the speech signal when the vocal tract is excited by a periodic signal from the vocal folds. This paper reports a novel instrument which uses a real-time, non-invasive technique to measure these resonances accurately during phonation. A broadband acoustic current source is located just outside the mo...
متن کاملComputer Modeling of Pharyngoesophageal Segment during Tracheoesophageal Phonation Using Finite Element Acoustic Models with Preliminary Validation
Introduction and aim: Total laryngectomy surgery is performed in patients with large or recurrent laryngeal cancer. Following removal of the larynx, tracheoesophageal (TE) voice is the gold standard for achieving phonation. The mechanisms underlying TE voice are not fully understood, but pharyngoesophageal (PE) segment vibration has been shown to play a key role [1]-[3]. The aim of this study w...
