Abstract
The subject of the present paper is the building of a limited domain speech synthesis system, where longer units, like words and phrases, can naturally be concatenated together. However, instead of building a single-purpose domain-oriented engine working with longer units, we show that a general-purpose TTS system can be used as a good emulation tool to ensure that a real domain-oriented engine will work correctly. Since the current general speech synthesis system embedding unit selection method concatenates short speech units (diphones), the selection algorithm has been modified to pretend the concatenation of words or even the whole phrases, while still concatenating diphones internally. The behaviour of the system is tested on two limited domains and its output is compared to the output of general (unmodified) version of the same TTS system. The results show clear encouragement for the build of the “real” domain-oriented engine.
