The fastest way to teach a child to use an alternative speaking device is The Tiny Talker Method.
The Tiny Talker Method helps children with communicative disabilities learn to use an augmentative and alternative communication (AAC) device in a more natural way.
By pairing the device with a storybook, children are able to see the symbols in the story, touch the corresponding sound buttons on The Tiny Talker device, and hear the device's response. This reinforces children's understanding by appealing to visual, kinesthetic, and auditory learning styles all at once. Lucas the Lion Loves The Tiny Talker is a fun and intuitive way to help children find their voice!
