CRITIQUE - ARTICULATORY ACOUSTIC RELATIONS AND THEIR ROLE IN SPEECH-PERCEPTION

These remarks are in response to ''Role of articulation in speech perc eption: Clues from production,'' by Bjorn Lindblom. It is suggested th at the form in which the lexicon is stored includes both segments and distinctive features, and this representation is neutral with respect to the articulatory and the acoustic domains. The process by which fea tures are determined from the sound requires that patterns of acoustic properties be identified. In developing models of speech perception, knowledge of articulatory-acoustic relations can be a guide in definin g these properties, but it is not necessary for the models to assign p rimary status to articulation.
