Comparative Performance Evaluation of Conventional, Whispering, and Monotone Vocoder Speech
William D. Voiers · The Journal of the Acoustical Society of America · 1965
Speech as processed by the AFCRL polymodal vocoder operating conventionally, as a whispering vocoder, and as a monotone vocoder was evaluated for intelligibility and speaker recognizability using the diagnostic rhyme test, the Fairbanks rhyme test, and a multidimensional voice-rating procedure. Predictions as to the effects of monotone and whisper vocoderization upon diagnostic rhyme-test scores and upon the information structure of voice ratings were confirmed by the test results.
