“To speak with the head—to hear with the eye”

“Melville Bell developed a written system of sounds called Visible Speech. To demonstrate its utility, he had his young sons wait in a separate room while audience members suggested a series of complex sounds, including phrases in foreign languages, nonsensical utterances, and non-speech sounds such as kissing and laughter. When summoned, the Bell children read their father’s notations and faithfully replicated the sounds. His work on speech improvement had a lasting impact on his son Alexander Graham Bell, who believed deaf people could learn to speak. ” (Source)
