Abstract
It is well known that speech errors in normal and aphasic speakers share certain
key characteristics. Traditionally, many of these errors are regarded as serial
misorderings of abstract phonological segments, which maintain the phonetic
well-formedness of the utterance. The current paper brings together the results of
several articulatory studies undertaken independently for both subject populations.
These show that, in an error, instead of one segment substituting for
another, two segments are often produced simultaneously even though only one
segment may be heard. Such data pose problems for current models of speech
production by suggesting that the commonly assumed dichotomous distinction
between phonological and phonetic errors may not be tenable in the current form
or may even be altogether redundant.
