Speech errors from an articulatory perspective; is there more than meets the ear?

For decades, the production and correction of speech errors has been a valuable source of information for linguists to model speech and language production processes. In general, errors were interpreted as originating at the cognitive level as a consequence of competing phonemes or features; one of them eventually “winning” and being produced. Evidence is accumulating, however, that suggest that the produced speech segments are frequently a blend of two abstract speech units and, in certain cases, likely originate at the articulatory level. Following this new direction, l present a series of electromagnetic articulography studies, conducted at the Oral Dynamics lab in Toronto, Canada, examining tongue twisters from an articulatory point of view, exploring how constraints at the articulatory level affect error patterns. In addition, I examined whether speakers use auditory information to control for these articulatory speech errors.
