XiSTS - XML in Speech Technology Systems

This paper describes the use of XML in three generic interacting speech technology systems. The first, a phonological syllable recognition system, generates feature-based finite-state automaton representations of phonotactic constraints in XML. It employs axioms of event logic to interpret multilinear representations of speech utterances and outputs candidate syllables to the second system, an XML syllable lexicon. This system enables users to generate their own lexicons and its default lexicon is used to accept or reject the candidate syllables output by the speech recognition system. Furthermore its XML representation facilitates its use by the third system which generates additional lexicons, based on different feature sets, by means of a transduction process. The applicability of these alternative feature sets in the generation of synthetic speech can then be tested using these new lexicons.
