Cognitive constraints on advance planning of sentence intonation.

Pitch peaks tend to be higher at the beginning of longer than shorter sentences (e.g., 'A farmer is pulling donkeys' vs 'A farmer is pulling a donkey and goat'), whereas pitch valleys at the ends of sentences are rather constant for a given speaker. These data seem to imply that...
