Cerevoice R ©is a unit selection speech synthesis system produced by Cereproc Ltd. The system was used to build small and large unit selection databases using the data supplied by the Blizzard Challenge 2006. The large database system was used as a baseline system while two experimental approaches for improving the quality of the small database system were(More)
Previous work in HCI has shown that ambiguity, normally avoided in interaction design, can contribute to a user’s engagement by increasing interest and uncertainty. In this work, we create and evaluate synthetic utterances where there is a conflict between text content, and the emotion in the voice. We show that: 1) text content measurably alters the(More)
In commercial systems the memory footprint of unit selection systems is often a key issue. This is especially true for PDAs and other embedded devices. In this years Blizzard entry CereProc R ©gave itself the criteria that the full database system entered would have a smaller memory footprint than either of the two smaller database entries. This was(More)
Building high quality synthesis systems with open domain vocabulary and a small audio database is a challenging problem, even when the targeted application is well constrained. Monophone unit concatenation (as opposed to diphone) is an approach that can compensate for the poor unit coverage that a small database implies. However, joining at phone boundaries(More)
