This study reports on a production experiment and a new computational model in an attempt to resolve the question of the status of floating Low tones in Ibibio. The pitch height of high tones (H), low tones (L) and downstepped high (!H) tones in a set of utterances spoken by an Ibibio speaker were first measured acoustically and secondly modelled computationally. Results show that there is a difference between a floating L and an overt L. Furthermore, the overt Low tone causes a higher degree of lowering than the floating Low tone.
