Importance of acoustic analysis in the differential diagnosis of adductor spasmodic and muscle tension dysphonia besides fiberoptic video laryngoscopy [PDF]

open access: yesLiječnički vjesnik, 2022
Introduction: Spasmodic dysphonia (SD) and muscle tension dysphonia (MTD ) are two different disorders with different etiology that influence the quality of voice, characterized by similar perceptual and acoustic features.

Age-sex variations in maximum performance measures of speech production [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1987
The maximum performance measures of speech production include: phonation volume, maximum phonation time, maximum expiratory pressure, maximum vocal SPL, physiological vocal frequency range, maximum articulatory force, and maximum syllable repetition rate.

Open Quotient Measurements Based on Multiscale Product of Speech Signal Wavelet Transform [PDF]

open access: yesResearch Letters in Signal Processing, 2007
This paper describes a multiscale product method (MPM) for open quotient measure in voiced speech. The method is based on determining the glottal closing and opening instants. The proposed approach consists of making the products of wavelet transform of speech signal at different scales in order to enhance the edge detection and parameter estimation ...

The listening talker: A review of human and algorithmic context-induced modifications of speech [PDF]

open access: yes, 2014
Speech output technology is finding widespread application, including in scenarios where intelligibility might be compromised at least for some listeners by adverse conditions.

Logopenic and Nonfluent Variants of Primary Progressive Aphasia Are Differentiated by Acoustic Measures of Speech Production [PDF]

open access: yesPLoS ONE, 2014
Differentiation of logopenic (lvPPA) and nonfluent/agrammatic (nfvPPA) variants of Primary Progressive Aphasia is important yet remains challenging since it hinges on expert based evaluation of speech and language production. In this study acoustic measures of speech in conjunction with voxel-based morphometry were used to determine the success of the ...

A New Approach to the Formant Measuring Problem

open access: yesProceedings, 2019
Formants are characteristic frequency components in human speech that are caused by resonances in the vocal tract during speech production. They are of primary concern in acoustic phonetics and speech recognition.

How to precisely measure the volume velocity transfer function of physical vocal tract models by external excitation. [PDF]

open access: yesPLoS ONE, 2018
Recently, 3D printing has been increasingly used to create physical models of the vocal tract with geometries obtained from magnetic resonance imaging. These printed models allow measuring the vocal tract transfer function, which is not reliably possible

Whole-word measures and the speech production of typically developing Dutch children

open access: yesClinical Linguistics & Phonetics, 2019
In this study, the phonological whole-word measure Phonological Mean Length of Utterance was applied to identify stages in the phonological acquisition of Dutch children. Ninety spontaneous speech samples of 47 typically developing Dutch children from a previous study were examined.
