Spoken language (SL) system development is an in-creasingly interdisciplinary effort. Speech-to-speech system development, for example, involves speech engineers, software engineers, phoneticians, and a variety of computational linguistic subdisciplines from morphology, syntax and lexicology through semantics and pragmatics, each with their own historically moti-vated terminology. In our experience this ‘terminology barrier’ makes communication between the disciplines unnecessarily difficult. As a contribution to reducing the terminology barrier we propose a set of new speech specific terminological principles and a proto-type term bank with an Internet interface for this spe-cific purpose. The result is one of the outputs of the spoken language working group of the LE EAGLES Phase II project (LE3-4244 10484/0).
