Abstract : The waver was more easily detected when heard over a loudspeaker than over headphones. Measurements indicated that in a live-room environment there were amplitude fluctuations in the vowels, in addition to the intended pitch modulation, and that the combined modulation was better detected than the pitch changes alone. Waver was detected better for vowels than for pure tones.
