<qa>  What is the apnea-hypopnea index?Two groups of participants will be examined: Group 1: primary snoring and Group 2: mild to moderate OSA patients apnea-hypopnea index 30hour who are not severely obese BMI 40 KgM2 and do not have significant structural abnormalities of the upper airway or muscle dysfunction. This preliminary investigation consists of a randomized controlled trial training versus sham training with two months of daily training 5 out of 7 days each week. A home sleep study including EEG will be performed before and following the training. The change in the apnea-hypopnea index adjusted for sleep stage and body position will be compared. Use of home sleep studies will dramatically reduce the cost of the study. A sleep technologist will educate subjects on performance of training maneuvers and meet with them weekly to observe the subjects technique and measure tongue strength. A training log will be kept by the subjects using training schedule sheets and training will be directly monitored at least 2 times weekly through with a study clinician electronically via facetime, skype or by direct observation.
