Rhythmic Expectancy in Continuous Speech Perception
The model concerns moment-to-moment listener expectancies based upon the dynamics of patterned speech movement. For convenience here we distinguish between (a) temporally short-lived (segmental) cues including coarticulatory effects and (b) all other cues (call them suprasegmentale) in continuous speech perception. Suprasegmental cues enable the listener to expect or anticipate the rough outlines of speech not yet heard. These suprasegmental redundancies include timing and hence generate listener expectancies in real time. At some given moment after prior context has been heard. suprasegmental processing load is lighter, with correspondingly greater efficiency in segmental processing. That is, segmental and suprasegmental processing can be said to interact.
