Measurements of pitch perception for F0 glides are described. The method of adjustment was prefered. Stimuli were FO glides centered at 220 Hz. The parameters under study were: the pitch glide extent (0, 0.2, 0.4, 0.8, 1.5, 3, 6, and 12 SemiTones (ST), i.e. 0, 2.5, 5, 10.17, 18.74, 38.17, 76.63, 155.56 Hz), the tone duration (50, 100, 200 and 300 ms), the pitch glide direction (rising or falling), and the extremity of pitch glide matched (beginning or end). The interpretation of the results shows that: 1/ perception correspond to a time-average of the frequencies present; 2/ the the higher extremity of the glides seems more important; 3/ there is an assymetry between rises and falls. The experimental results are also compared to models of pitch integration for F0 glides, namely Rossi's 2/3 rule, and d'Alessandro and Castellengo's weighted time-average model.
