Vocal fold adjustments in aspirated and unaspirated stops in Danish.

Vocal fold adjustments in Danish aspirated and unaspirated stops were investigated by electromyography, photo-electric glottography, and fiberoptic stills. The results show that these two stop types are produced primarily by different types of glottal gesture, rather than by a different timing of the glottal and supraglottal articulations. Other, more general aspects of glottal behaviour in relation to aspiration and devoicing in stops are also discussed.
