All Night Analysis of Snoring Signals by Formant Features

摘要

This paper presents our preliminary research on all night analysis of formant features extracted from snoring signals (SS), which can be used to find changes of anatomical structure in the upper airway (UA) for patients suffering from Obstructive Sleep Apnea-Hypopnea Symdrome (OSAHS). All night analysis of formant features has a significance to reveal the relationship between physiological or anatomical mechanism and SS. It could be potentially helpful for doctors to conduct an accurate and efficient surgical plan.
