IPOX versus YorkTalk
Development history
Related developments
- French version of YorkTalk (Eric Keller, Switzerland)
- SynPhonics Concept-To-Speech system (Günther et al 1994)
Differences with YorkTalk
- separate rule compiler (clear separation of linguistic rules and procedural algorithms)
- metrical tree as central data structure (YorkTalk does not take full advantage of metrical structure)
- rule formalism allows rule developer to state generalizations across phrase structure rules separately by means of rule templates
Current limitations
- development of IPOX has not progressed as far as YorkTalk
- rules for synthesis of British English mono-syllables from an earlier version of YorkTalk ("Oxford version")
- rules for polysyllabic words and utterances rather preliminary
Illustration
- this is a sentence, spoken by a non-segmental synthesis system (YorkTalk)
- this is a sentence, spoken by an all-prosodic synthesis system (IPOX)
