Stimuli

• Waveforms of the vowels
• Formant frequencies and bandwidths (as a table in latex format). Frequencies are from T. Hirahara and H. Kato (1992). "The effect of F0 on vowel identification," in "Speech perception, production and linguistic structure," Edited by Y. Tohkura, E. Vatikiotis-Bateson and Y. Sagisaka, Tokyo, Ohmsha, 89-112).
• Starting phase spectrum common to all vowels, in radians. Line #N represents the phase of the harmonic of rank #N.
• Spectral envelopes (amplitude in dB) from 0 to 10 kHz at 10 Hz intervals.
