The production of plosive consonants with an ingressive airstream is an often-encountered speech characteristic of deaf individuals. The present research examined the production of ingressive plosives employing an analysis-by-synthesis strategy. Production of ingressive plosive patterns appears related to specific alterations in synthesizer control parameters: supralaryngeal vocal-tract volume, glottal aperture, and occlusion duration. It is hypothesized that production of ingressives by deaf speakers in this study resulted from laryngeal lowering to increase vocal-tract volume, glottal closure during the occlusion interval, and extended occlusion duration.
