Consonant effect on F0 Consonant effect on F0

Prevocalic voicing triggers tonogenesis in Chinese and some Asian languages

Voiced onsets lower onset F0 Well-documented in tonal and non-tonal languages

Raised/lowered F0 can serve as a perceptual cue for consonantal feature

Higher F0 as a perceptual cue for aspiration in

Cantonese (Francis et al. 2006)
