An experiment was conducted to determine whether the deep structure or the surface structure clause is more important as a speech planning unit, and whether syntactic decisions are made during sentence production. Results were discussed in relation to previous studies of pausing and speech disruption. (Author/CTM)

Five experiments examined how the duration of a word spoken in a sentence is influenced by the grammatical category to which it belongs, and the position of the word in a constituent. The findings indicated that a binary distinction between major and minor categories is sufficient for a theory of speech timing and synthesis. (Author/JAC)
