title: The laryngeal vestibule, voice quality and paralinguistic markers.
abstract: The laryngeal component of voice quality markers has been quantified in the present study, suggesting that the laryngeal vestibule and lower pharynx play an important role in voice quality. Findings also show that voice quality can be partly described in terms of laryngeal configurations and that a knowledge of these configurations may be useful to the laryngologist, speech pathologist and singer. Twenty-five voice qualities were videorecorded, using a nasal fiberscope. Still photographs were taken for each voice quality and distance measurements made on each one for 15 laryngeal parameters. The raw data were normalized, sorted from high to low, turned into scalar values and processed to establish which parameters exhibited similar functions, which photographs were essentially identical, and in what respect any two photographs were different. Each voice quality was seen to be associated with a different, describable and quantifiable laryngeal configuration.
