Considérations tonologiques du twi

- Résumé : Twi is a register tone language spoken in Ghana, West Africa. It has a two tone system (high/low) and the downstep phenomena. In this study, some phonological aspects of Twi tones are described and acoustic measurements are carried out to investigate for differences between vowel quality in the two groups. Two adult Twi male and female speakers produced a series of isolated words belonging to the two phonological classes. The evidence from our acoustic data, confirming results obtained in a preliminary study, is for high tones to have higher fundamental frequency values than low tones. Acoustic results also confirm that high and low tones show sparse qualitative as well as sparse syllabic durational differences. The tendency is also for low tones to have lower F1, higher F2 than the high counterparts.
