At the end of the 90s the European spaceplane programme HERMES is planned to be carried out. Presently, a telecommunication subsystem is under development. This development is directed towards video and audio communication. The definition of the audio communication system includes the system design as well as the development of different speech coders that are geared to the specific conditions of the HERMES mission. For being able to choose the best system, each coder must be validated. A reliable quality judgement requires a test where the functional aspect of the object is paid attention to. In order to open up the possibility to collect data for this specific application, new intelligibility tests have been designed.
