Internal and contextual cues to tone perception in Medʉmba

This study presents results of an identification experiment with speakers of Medʉmba, a Grassfields Bantu language, aimed at evaluating the relative effects of f 0 and duration in cuing tonal contrasts, as well as the role of lexical vs non-speech pitch contexts in biasing tone perception. Results show that duration is a cue for tone perception, with the influence of duration strongest where target f 0 values were lower. Lexical tone perception is also sensitive to the identity of a preceding lexical tone, but not to the presence of a preceding non-speech pure tone.
