Recent proposals to treat phonetic representations as the semantic interpretation of phonological representations are technically problematic to implement. The main di culty is that phonological representations are discrete while phonetic representations are continuous which makes the standard method of describing semantic interpretation as a homomorphism between sortally equivalent algebras hard to generalize. The paper solves the technical problem by i n troducing a notion of homomorphisms.

Next a.e. homomorphisms are rigorously de ned and the semantic relationship between phonologicaland phonetic categories is made explicit in terms of these homomorphisms. Finally constant target triphone models, which play a central role in speech recognition, are reconstructed in this semantic framework.
