Formant Frequencies and Bandwidths in Relation to Clinical Variables in an Obstructive Sleep Apnea Population

摘要

Objectives. We investigated whether differences in formants and their bandwidths, previously reported comparing small sample population of healthy individuals and patients with obstructive sleep apnea (OSA), are detected on a larger population representative of a clinical practice scenario. We examine possible indirect or mediated effects of clinical variables, which may shed some light on the connection between speech and OSA.
