Résumé

Postulating the existence of abstract representational units appears useful in speech research. For instance, such units can be used to partition a large lexicon for word-candidate hypothesization [8] [4], or to specify phonetic deletion and modification sites. However, since such linguistic representations have at best an indirect realization in the physical signal. it has proven difficult to build classfiers for these units. Therefore, recognition systems generally use less abstract units such as spectral templates. We argue that the difficulty of classifying abstract units docs not preclude using these units in recognition. In particular, constraint-based systems provide a mechanism for exploiting abstract linguistic knowledge m the acoustic level.
