An oral transliterator provides communication access to a person who is deaf or hard of hearing and who uses speechreading and speaking as a means of communicating. The oral transliterator, positioned in front of the speechreader, inaudibly repeats the spoken message, making it as speechreadable as possible. This is called Expressive Oral Transliterating. An oral transliterator also can audibly voice the spoken message of the person who is deaf or hard of hearing for the hearing audience. This is called Voicing or Voice-Over. This paper provides information on oral transliterating.
