A d/Deaf interpreter (DI) is an individual who is deaf or hard of hearing and possesses excellent communication skills in both ASL and English. They have been trained in interpreter ethics and may also have specialized communication training in use of gesture, mime, drawings, and matching sentence structure and language of the deaf person they are interpreting. The DI also has an extensive knowledge and understanding of deafness and of Deaf culture. Some people believe that the use of a d/Deaf & hearing interpreter team increases the level of accuracy in the overall transmission of information.
