We present data on convergence in the Switchboard corpus, ad-dressing differences across measures and across speakers. Wemeasured convergence in four characteristics, to test consis-tency in related and unrelated measures: F0 median, F0 vari-ance, speech rate, and odds of the fillers uh and um. Conver-gence was significant in all measures and exhibited variationboth between individuals and within individuals. Most notably,convergence in one measure was not predictive of convergencein other measures, except between closely related measures.The results demonstrate some of the limitations of generaliz-ing convergence results from one measure to other measures.
