PHONATION CURVE / A device helps hearing-impaired children speak


The product can effectively help hearing-impaired children learn to speak. Hearing-impaired children missed the best language learning time when they were one to two years old, making it more difficult for them to learn to speak later.
The product combines bone conduction technology with piezoelectric ceramic vocal cord recognition technology, solves the listening and speaking obstacles of hearing-impaired children, and forms an integrated product.What’s more, the product combines an online teaching mode with a mobile phone to help those children with hearing impairment learn to speak autonomously.
