In general purpose concatenated waveform synthesis an exhaustive waveforms inventory is needed. Our SPRUCE system is syllable/word based, but for general purpose work its inventory needs examples of all syllables. The high-level synthesis engine used to generate the phonology/prosody of utterances is general purpose - but its use is constrained by small low-level inventories of re-combinable waveforms. This feasibility study reported here was carried out to determine whether we could take one of the word based limited domain versions of the system, and make it more general by excising syllables from existing polysyllabic words and recombining them into new words. Initially the study treats temporal rather than spectral considerations.
