Clause-internal filled pauses and preceding peak F0 values for American and British English speakers were analyzed to determine whether the intonation of filled pauses is relative to, or independent of, prior prosodic context. Higher peaks were found to be systematically associated with higher filled-pause values within speakers, supporting the "relative" hypothesis. In modeling this relationship it was found that a linear model, in which filled-pause F0 was expressed as an invariant (over speakers) proportion of the distance between peak and baseline, produced results nearly identical to those of a two-parameter model in which the coefficients of peak and baseline were allowed to vary freely. Analyses of additional variables showed the model to be less appropriate for filled pauses after sentence-initial peaks, but unaffected by temporal variables
