A sign language interpreter must accurately convey messages between two different languages. An interpreter is there for both deaf and hearing individuals. The act of interpreting occurs when a hearing person speaks, and an interpreter renders the speaker's meaning into sign language, or other forms used by the deaf party(ies). The interpreting also happens in reverse: when a deaf person signs, an interpreter renders the meaning expressed in the signs into the oral language for the hearing party, which is sometimes referred to as voice interpreting or voicing. This may be performed either as simultaneous or consecutive interpreting. Skilled sign language interpreters will position themselves in a room or space that allows them to be seen by the deaf participants and heard clearly by hearing participants, as well as be in a position to hear and/or see the speaker or speakers clearly. In some circumstances, an interpreter may interpret from one language to another whether that is English to British Sign Language, English to American Sign Language, Spanish to English to American Sign Language and so on.
