Speech therapist Dario Lindes, inventor of the snorefree method.

The SnoreFree® method

The SnoreFree method is a unique training program developed by Viennese speech therapist Dario Lindes and has been successfully practiced for more than 12 years.

In more than 80% of the patients, a marked improvement in the quality of sleep as well as a significant reduction in snoring noises can be observed after only a few weeks.

The muscular tissue weakness in the inner throat and pharynx, which causes the soft tissues to collapse during sleep and thereby obstructs the flow of breath, is specifically strengthened by the snorefree method, as in voice training for singers and speakers.

With only 10 minutes daily training

snoring can be significantly reduced and the quality of sleep can be noticeably improved. Like a fitness training, SnoreFree strengthens the muscle build-up specifically with sensory and motor exercises for mouth and throat.

Because deep and healthy sleep is an important factor for a better quality of life, better productivity and performance in everyday life, and last but not least, for harmony in the bedroom.

The research

Dario Lindes has already carried out a pilot study at the Vienna General Hospital in 2007, in cooperation with the ENT department and the pulmonological sleep laboratory/2. Internal, in which his treatment method of logopaedic anti-snoring training was positively evaluated.

The result of the basic research can be viewed here:

In practice

Conclusion: The orofacial myofunctional therapy from speech therapy effectively helps to reduce objectively measured snoring production and intensity after only three months. It can help a large part of the population to sleep better and more relaxed.

The SnoreFree method treats the inner muscular weakness with exercises for


Front Tongue

Rear Tongue


The root cause

Snoring is almost always caused by muscular weakness in the neck and throat. The tissue slackens and blocks the airway during sleep.


This can result in more serious symptoms such as chronic daytime fatigue, general performance losses and, in the long term, even stroke or heart attack.

Not only does this disturb your partner while you sleep, it can also become a health problem for yourself if snoring causes breathing stops (Apnea).

Worldwide clinical studies

This was followed by a whole series of clinical studies around the world, which dealt with the training-related influence of snoring and nocturnal respiratory flow disorders and showed a positive effect of oral exercises on sleep-related breathing sounds and breathing stops (sleep apnea).

Original quotes from these papers:

  • Physical exercise is efficient in improving the quality of life in OSA patients,
  • Improvement in quality of life is comparable to that found with CPAP treatment,
  • Daytime sleepiness is reduced regardless type of physical exercise,
  • positively impacts severity of OSA can be measured.
