Fig. 2: Z-score values of f0 directionality for different speakers.
From: Multi-class identification of tonal contrasts in Chokri using supervised machine learning algorithms
a S1_F, b S2_F, c S3_M, d S4_M, e S5_F, f S6_F, and g S7_F, and the (h) speaker-wise average are shown. M indicates the gender of the speakers- M for males and F for females. The f0 directionality entails the division of the f0 track into eleven equidistant time points, ranging from the onset (0%) to the offset (100%) of the f0 trajectory. Different tones include four level tones- extra high (EH, in blue color), high (H, in red color), mid (M, in black color), low (L, in green color), and a contour tone (MR, in purple color).
