Relay interpretation
Relay interpretation means interpreting from one language to another through an intermediate language. This mode of interpretation is often used for monolingual speakers of languages of limited diffusion, including select indigenous languages. In relay interpreting, the first interpreter listens to the speaker and renders the message into the intermediate language. The second interpreter receives the message in the intermediate language and interprets it into a third language for the speaker who speaks neither the first nor the second language.
