Auditory verbal therapy FAQs Should my child learn British Sign Language (BSL) as well as having Auditory Verbal Therapy? Most parents who come to us want their children to learn to talk through listening. Our experience tells us that this is an achievable goal for the majority of children with a hearing loss. 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 usually advise waiting until these listening and spoken language skills are firmly established before teaching BSL to your child. Some parents choose to learn BSL while participating in their child's Auditory Verbal programme. We fully support the choices that parents make for themselves and their child.
