Some problems of interarticulator phasing as an index of temporal regularity in speech.

Tuller, Kelso, and Harris (1982) offered evidence that the relative timing of articulators in speech remains constant over changes in stress and speech rate. Their evidence is discussed in the light of the methods used, and alternative approaches are suggested. Further, the statements are compared with those of an earlier study within the same theoretical frame, and the implications for a model of speech production are briefly discussed.
