Title: Inducing Concatenative Units from Machine Readable Dictionaries and Corpora for Speech Synthesis
Subject: Evelyne Tzoukermann,Judith L. Klavansy Inducing Concatenative Units from Machine Readable Dictionaries and Corpora for Speech Synthesis
Description: The purpose of this research is to determine the best method for deciding on an optimal set of concatenative units for concatenative speech synthesis. Of the two main approaches to speech synthesis: segmental synthesis and rule-based synthesis, the former relies heavily on the successful choice of concatenative units. Segmental synthesis consists of concatenating segmental units (diphones, triphones, etc); rule-based synthesis consists of the computation of control parameters based on pre-established rules. Deciding on the set of diphones is quite straightforward in the sense that it suffices to take the phoneme inventory of a language, and simply combine each phoneme with every other one. For example, taking the approximately 35 French phonemes, 1225 phonemic pairs (35x35) constitute the complete and exhaustive starting diphone inventory. On the other hand, deciding on the set of triphones, quadriphones and larger units raises difficult questions about the nature of phonemes in a give...
