Is your child still mispronouncing the K sound? KooTreeni's motivating exercises will take them step by step to a fluent K sound using methods developed by Finnish speech therapists. The sounds are almost invariably learned through regular home practice, and KooTreeni is an effective tool for this. The application contains versatile tasks for practicing pronunciation through various gamified exercises, following the structure used in speech therapy for learning K. The application also contains comprehensive instructional videos from a speech therapist to support parents. KooTreeni is suitable for children of all ages. However, we recommend that an adult and child use KooTreeni together, so that the adult can support the child when necessary and at the same time spend quality time learning together.
