Speech Synthesis Evaluation

Report on the Third ESCA TTS Workshop Evaluation Procedure.
Jan P. H. van Santen and Louis C. W. Pols and Masanobu Abe and Dan Kahn and Eric Keller and Julie Vonwiller.
Proceedings of the 3rd ESCA Workshop on Speech Synthesis.


Evaluation of speech synthesis traditionally considers intelligibility and naturalness. More recently, expressivity has become an issue with the increasing demand for expressive voices. Due to the multitude of aspects involved, there is no agreed standard for evaluation of speech synthesis systems. Since 2005, the Blizzard Challenge is an annual joint event for comparing speech synthesis technologies with a common database.
