Abstract |
This paper describes the first TTS evaluation campaign designed for Spanish.Seven research institutions took part in the evaluation campaign and developeda voice from a common speech database provided by the organisation. Eachparticipating team had a period of seven weeks to generate a voice. Next, a setof sentences were released and each team had to synthesise them within a weekperiod. Finally, some of the synthesised test audio files were subjectivelyevaluated via an online test according to the following criteria: similarity tothe original voice, naturalness and intelligibility. Box-plots, Wilcoxon testsand WER have been generated in order to analyse the results. Two mainconclusions can be drawn: On the one hand, there is considerable margin forimprovement to reach the quality level of the natural voice. On the other hand,two systems get significantly better results than the rest: one is based onstatistical parametric synthesis and the other one is a concatenative systemthat makes use of a sinusoidal model to modify both prosody and smooth spectraljoints.Therefore, it seems that some kind of spectral control is needed when buildingvoices with a medium size database for unrestricted domains. |
