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