"Liaison interpreting is consecutive interpreting which enables conversation, discussion, etc. between speakers of two different languages.", whereas consecutive interpreting refers to "longer speeches (rather than two-way conversation)", this according to Newcastle University.

At the University of Nottingham, an English/Chinese course refers to bi-lateral interpreting learning with these aims :

"This module aims to equip students with the advanced knowledge and skills required to provide Bi-lateral interpreting between English and Chinese. It focuses on delivering the speaker’s intended effect on the audience, with emphasis on the overall performance of the interpreter and the impact of interpreting upon the audience, in addition to accuracy and completeness. It trains core skills of projecting the speaker and delivering effects such as humour, indirect requests and intended impression. Techniques are developed for communication with the audience, such as eye-contact, use of pauses and use of voice. The module is workshop-led to maximise practice in class, focusing on two of the most challenging scenarios – speeches and presentations."
