Relative salience of intonation fall and pause as cues to the perceptual segmentation of speech in an unfamiliar language.

The modification of subjects' attention by two prosodic features was investigated using their reaction times to a nonspeech stimulus which coincided with these features. By using a foreign language unfamiliar to the subjects (Czechoslovakian), the influence of semantic and syntactic knowledge was controlled. The results indicate that for native speakers of English intonation fall is a relatively more important cue to the perceptual segmentation of speech than is pause.
