The evaluation results of the 2010 Blizzard Challenge come out! The followings are MOS scores on naturalness for task EH1, EH2 and ES1. My new HTS systems, which I introduce in the past news, are system V. System A is natural speech for reference and System B is a standard Festival unit-selection system.

Task EH1 (4 hours of speech data, Speaker RJS)

According to Wilcoxon signed rank tests with alpha Bonferoni correction (1% level), the system V is not as good as systems M, J, T. There is no significant differences between system V and B.

Task EH2 (1 hour of speech data, Arctic sentences, Speaker Roger)

Likewise, according to Wilcoxon signed rank tests with alpha Bonferoni correction (1% level), the system V is the second best and is significantly better than B.

Task ES1 (100 sentences of arctic sentences, Speaker Roger)

Likewise, according to Wilcoxon signed rank tests with alpha Bonferoni correction (1% level), the systems M and V are the equal best.

In summary, the new HTS system performs very good on small dataset and 1 hour of speech data set. Even on 4 hours of speech data set, it is as good as the Festival unit-selection system.
