sylby is a language learning app that allows users to improve their pronunciation in the language they are learning. We rely on state-of-the-art AI technology that is able to provide users with detailed feedback in real time on the one hand, and on the other hand offers the possibility to address the specific needs of individual learners. In doing so, the learner’s own progress, linguistic background, but also self-set goals are taken into account and self-confidence is promoted. In addition, we offer our users a logopedic approach in which we use targeted speech muscle training to build up or activate the muscles necessary for the formation of certain sounds. sylby is the all-round package, the personal, intelligent pronunciation assistant in your pocket. And sylby is fun, too!
