K-Max: a tool for estimating, analysing, and evaluating tonal targets

Antoin Rodgers


This paper presents a novel approach to the identification of tonal targets within the Autosegmental Metrical (AM) framework using the second time derivative of the f0 contour. The approach is implemented through an interactive Praat script called K-Max, which allows users to annotate salient turning points on a text grid as well as correct tracking errors and remove micro-prosodic events on the pitch contour. The script also generates a resynthesized model of the pitch contour based on the annotation of turning points, which is not typical in the AM approach. The theoretical rationale for the overall approach is presented, followed by a description of its implementation. The paper then discusses the success of the technique in identifying tonal targets in relation to user intuitions and acceptability judgments regarding the resynthesized f0 contours. Finally, it provides examples of its potential application regarding issues such as downstep and f0 plateaux, arguing that the over-specification of tonal targets required in the resynthesis component can facilitate analysis of the relationship between underlying phonological structures and their realisation in the f0 contour.
