A 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 کاملFEM analysis of aspirated air flow in three-dimensional vocal tract during fricative consonant phonation
This paper deals with estimations of aspirated air flow in a threedimensional vocal tract during fricative consonant phonation using the Finite Element Method (FEM). The shape of the 3-D vocal tract during phonation of fricative consonant /s/ is reconstructed from 32 coronal Magnetic Resonance (MR) images. MR images of the dental crown that contains a small amount of water were obtained using a...
متن کاملEstimation of Vocal Tract Shape during Stop Closures
The display of intensity, pitch, and vocal tract shape is considered to be helpful in speech training of the hearing impaired. Vocal tract shape estimation, based on LPC and other analysis techniques, works satisfactorily for vowels but generally fails during stop consonants due to very low signal energy. Our estimation of vocal tract shape is based on reflection coefficients obtained from LPC ...
متن کاملAir-pressure, Vocal Fold Vibration and Acoustic Characteristics of Phonation during Vocal Exercising. Part 1: Measurement in Vivo
The study investigates differences between three most widely used methods in voice training and therapy: Phonation into a resonance tube with the outer end in the air or submerged 2–10 cm in water (‘water resistance therapy’ with bubbling effect), and phonation into a very thin straw. One female speech trainer served as subject. Acoustic and electroglottographic (EGG) signals, and both mean and...
متن کاملAir-pressure, Vocal Folds Vibration and Acoustic Characteristics of Phonation during Vocal Exercising. Part 2: Measurement on a Physical Model
The contribution aims to provide material that can be used in development of more realistic physical as well as theoretical models of voice production. The experimental set-up, methodology and the results of measurement of airflow rate, subglottal, oral and generated acoustic air pressures are presented together with the simultaneously measured flow-induced vibrations of a vocal folds replica, ...
