Jaw kinematics in hearing‐impaired speakers

HearingImpaired Elderly Listeners

The Modified Rhyme Test (MRT), recorded using natural speech and two forms of synthetic speech, DECtalk and Votrax, was used to measure both open-set and closed-set speechrecognition performance. Performance of hearing-impaired elderly listeners was compared to two groups of young normal-hearing adults, one listening in quiet, and the other listening in a background of spectrally shaped noise d...

Lingual Kinematics in Dysarthric and Nondysarthric Speakers with Parkinson's Disease

Articulatory dysfunction is recognised as a major contributor to the speech disturbances seen in Parkinson's disease (PD). The present study aimed to compare lingual kinematics during consonant production within a sentence in eight dysarthric (DPD) and seven nondysarthric (NDPD) speakers with PD with those of eleven nonneurologically impaired normal participants. The tongue tip and tongue back ...

Laryngeal kinematics in voiceless obstruents produced by hearing-impaired speakers.

During normal production of voiceless consonants several events occur simultaneously in the vocal tract. These events must be temporally coordinated. Earlier work has indicated that a breakdown in interarticulator timing can contribute to the characteristic voiced-voiceless errors produced by hearing-impaired speakers. The present study examines kinematic details of the laryngeal articulatory g...

Coarticulation of jaw movements in speech production: is context sensitivity in speech kinematics centrally planned?

Coarticulation in speech production is a phenomenon in which the articulator movements for a given speech sound vary systematically with the surrounding sounds and their associated movements. Although these variations may seem to be planned centrally, without explicit models of the speech articulators, the kinematic patterns that are attributable to central control cannot be distinguished from ...
