Previous research has investigated compressed speech in the continuous speech context but has not investigated the effect of compression on short phrases such as might be uttered by an automated voice warning system. The potential benefits of this technology are decreased system memory requirements, decreased message transmission time or increased message length. Undergraduates (N=137) were tested in small groups to determine intelligibility of aviation-related short phrases. The design involved three rates of speech compression, three levels of pitch adjustment, male or female speaker, and male or female listeners. Significant differences were found for amount of compression, amount of pitch adjustment and the compression x pitch x sex of speaker interaction. These results are interpreted as supporting the use of compressed speech for automated voice warning systems in the cockpit.
