About Us

SpeakTX’s Estonian version Kõneravi.ee was launched in 2013 as a result of cooperation between Cognuse LLC and six Estonian speech therapists. It was originally meant as a tool to support the traditional methods of speech therapy, and its main purpose was to provide interactive exercises for children and aphasia patients. Various groups of people were engaged in its development from early on, such as people with speech disorders and their associations, the Estonian Association of Speech Therapists, as well as hospitals and private businesses. The wider aim is to make the speech therapy service more effective and more widely available across the world.
