When addressing access needs please ask the Deaf, late-deafened or Hard of Hearing AA member what form of translation works best for them. There is no one right answer to this question.
Deaf, late-deafened, and Hard of Hearing individuals are not all educated in the same way. Some attended Deaf institutes, some were mainstreamed, and others attended Oral schools. Some people became deaf (late-deafened) after they learned to speak and read English.
The primary language used varies between individuals. American Sign Language is often the primary language used by people who are born deaf. For many Deaf American Sign Language is their first/primary language and they do not always have the same fluency or understanding of written English. Also, some people who are born deaf do not speak/voice.
