How perception is guided by production has led to three main theories: no necessary production-perception relationship (eg., automatic speech recognition); speaker adaptations to auditory requirements for speech; or listeners' perceiving linguistically significant actions ("gestures"). Listeners handle acoustic complexity, but is a link with production typical? One link, individual differences (where perception matches production), is compatible with theories predicting separate processes. Second, perceptual parsing, shows listeners perceptually undo overlapping articulation (vowel-to-vowel coarticulation; F0 in vowel, consonant and intonational distinctions; and duration in vowels and consonants). Third, vocal imitation, appears early in infants, but adult listeners can imitate a changed vowel as quickly as a simple (nonchoice) response; a tight link seems to persist beyond the learning stage. These lines of research indicate a close link between production and perception. We have yet to explore all the implications, but it has become clear the links exist.
