Ogmios: the UPC entry for the Albayzin 2010 TTS Evaluation

This paper describes Ogmios, the UPC TTS system that was used in the 2010 Albayzin Evaluation. Ogmios is a concatenation system that builds the synthetic sentence from demiphones selected from the training database. In this evaluation round, the database was provided by the organization and it has been phonetically transcribed and segmented automatically using using the development tools included in Ogmios. Based on the segmentation the synthetic voice is build. Each voice includes the segmental inventory (waveforms of acoustic units), prosodic models (breaks, segmental duration and f0 prediction models) and the weights of the selection cost function. In order to have a better prosody models, in this evaluation external data has been used to ensure better prosodic coverage.
