"ARCTIC -- A standard phonetically balanced speech database for speech synthesis research" John Kominek and Alan W Black Although there are many standardized databases for evaluating speech recognition research there are almost none for speech synthesis. In order to help address this issue we have constructed new single speaker phonetically balanced databases that will be distributed without restriction for use in evaluation, algorithm comparison and as base-line voices for the speech synthesis community. This talk will present the motivation behind providing these as well as a detailed description of how they were designed, recorded and how baseline voices are built. We will also present our intention for their use in the immediate future.
