Study summary

The aim of this study is to examine whether voice acoustic properties has an influence on sleep apnea. Sleep apnea syndrome is defined as a sudden stop of more than ten seconds multiple times during sleep. The syndrome is common especially among men and occurs in 2%-4% of the population aged 30-60. The syndrome diagnosis is performed by an ENT (Ear, Nose and Throat) physician. The diagnosis is based on evaluation of anatomical structures in the sound path (nose and throat, jaw, pharynx and oral cavity) and a Polysomnography (PSG) test which quantifies the number and duration of breathing pauses during night sleep and additional parameters that monitor sleep. The syndrome has many negative consequences for those who suffer from it, including fatigue , lack of concentration, hypertension, diabetes ,heart disease, stroke and even death. Therefore, early diagnosis is important.
