Abstract

this paper a procedure for the construction of event relations at the phonetics/phonology interface is presented. The approach goes further than previous formal interpretations of autosegmental phonology in that phonological relations are explicitly related to intervals in actual speech signals as required by a speech recognition system. An event structure containing the temporal relations of overlap, precedence and inclusion is automatically constructed on the basis of an event lattice with time annotations derived from the speech signal. The event structure can be interpreted linguistically as an autosegmental representation with assimilation, long components or coarticulation. The theoretical interest of this work lies in its contribution to the solution of the projection problem in speech recognition, since a rigid mapping to segments is not required.
