A trend in both civil and military cockpit design is to incorporate some kind of speech system in the presentation of information. The decision has been made by Swedish Air Material department to introduce suitable speech systems in the aircraft Viggen and in the aircraft Gripen. A flight simulator experiment is used to investigate the following alternatives for ground collision warning: two types of speech generation, synthesized and digitized, female and male voices, six different words, lamp warning. To be able to create a realistic flight mission, a specific test method is designed. The flight task consists of head up as well as head down flying and the missions contain realistic ground collision warning situations. A tape recorded from authentic radio communication is used as a realistic background. As a further test of intelligibility for the different speech systems, unknown randomly positioned flight phrases are included. The results are unambiguous regarding the preference for speech systems but not so pronounced for the choice of warning words.
