Is speech temporally segmented? Comparison with temporal segmentation in behavior.
Phrase durations in spoken German and Korean were examined for temporal segmentation like that in behavior. Lines of poetry, which may be regarded as semantic units equivalent to action units in behavior, were found to be temporally segmented but, unlike behavior, there is a significant effect of language/culture on segment length. The lengths of the pauses made between lines while reading poetry were used to define possible semantic segments in reading prose, retelling a story, free speech, and telephone messages. No temporal segmentation was found, each situation resulting in a different distribution of phrase durations. These results are discussed in terms of a possible evolution of language from the motor system.
