Cynthia B. Roy 
Interpreting As a Discourse Process [PDF ebook] 

This book studies interpreting between languages as a discourse process and as about managing communication between two people who do not speak a common language. Roy examines the turn exchanges of a face-to-face interpreted event in order to offer a definition of interpreted events, describe the process of taking turns with an interpreter, and account for the role of the interpreter in terms of the performance in interaction.
