Résumé :

The custom of lip-plate insertion, as practiced by the Chai people, has an effect on the speech of women since it alters articulators needed for speech production: the lower lip and the lower incisors. Due to the effect of this practice, women cannot produce bilabial and dental consonants in their own language. Vowels are also affected, but the presence of the lip-plate does not affect the tonal system. This study further examines ways in which the lower lip and lower incisor mutilations are compensated for, and the acoustic effects involved in the ‘lip-plate speech’ as well as its implications for phonological theory. © 2001, International Phonetic Association.
