The purpose of the present study was to investigate the recognition of synthesized, compressed speech under helicopter noise vs. ambient noise conditions. Subjects performed an isolated word recognition task for stimuli generated by the VOTAN V-5000A speech synthesizer/recognizer. Results indicated that recognition performance, both in terms of percentage correct and average response time, deteriorated as a function of speech compression and level of noise. Implications of these results for the employment of compressed, synthesized speech warning systems in rotary wing aircraft are discussed.
