Pitch Reset in Akan Subordinate Clauses

This study explores how lexical tone interacts with intonation in Akan, focusing on pitch reset as a prosodic cue in complex declaratives. Pitch reset – an upward shift in fundamental frequency (f0) following declination – has been documented in various African languages, and in Akan by Kügler (2016, 2017). However, its role in Akan remains underexamined. Whereas Kügler analysed embedded and coordinated clauses, using a controlled production experiment with five native speakers of Asante Twi, we analysed conditional and temporal subordinate clauses to determine whether pitch reset signals prosodic boundaries. Results show that Akan speakers employ pitch reset before subordinate conjunctions, often accompanied by a pause, to mark clause boundaries, while in Kügler’s study pitch reset was not attested at all with coordinated clauses and was attested in complementizer sentences after the complementizer. Speakers pre-plan utterances by initiating the main clause at a higher pitch to maintain declination, and the degree of reset is influenced by lexical tone: resets are more pronounced on High tones and smaller on Low tones. These findings advance understanding of tone–intonation interaction in Akan and suggest that pitch reset functions as a robust cue to prosodic phrasing in tone languages. Limitations include sample size and potential effects of language attrition; future research should examine other conjunctions, matrix clause types, and dialectal variation.
