Across three separate investigations, this dissertation documents work examining the role of higher-order processes and cognitive effort during the top-down compensatory repair of degraded speech, specifically perceptual restoration. Perceptual restoration is a phenomenon where a listener can perceptually restore or repair speech…

The purpose of this comprehensive bibliography (approximately 200 items) is to facilitate the clinician's role in assessing and planning intervention for speech production of hard-of-hearing and deaf individuals.

Purpose: This study investigated formant frequencies for their role as acoustic and perceptual correlates to the place of articulation of Cantonese final stops produced by profoundly hearing impaired speakers. Method: Speakers were 10 Cantonese adolescents (mean age = 13;5 [years;months]) who were profoundly hearing impaired (HI). Control speakers…

A lightweight accelerometer has been used to produce a waveform related to the glottal acoustic output when attached to the throat of a speaker, and to provide an indication of acoustic coupling to the nasal cavities when attached to the external surface of the nose. Examples of signals produced by the accelerometer are shown, and possible…

The present paper comprises an overview of techniques using ultrasound in speech (re)habilitation. Ultrasound treatment techniques have been developed for English lingual stops, vowels, sibilants, and liquids. These techniques come from a series of small "n" studies with adolescents and adults with severe hearing impairment, residual…
