Auditory verbal therapy FAQs We would like our child to learn British Sign Language (BSL) too. What would you advise? At AVUK, we are interested in your hopes and aspirations for your child and we want to help you achieve these goals. Most parents who come to us want their children to learn to listen and talk. Our experience tells us that this is an achievable goal for the majority of children with a hearing impairment. Spoken language learning is time-sensitive: there is a relatively short window of time in which children’s brains are able to learn to make sense of sound. Therefore, if developing spoken language through listening is your aim, we would advise waiting until these language skills are firmly established before teaching BSL to your child.
