To obtain the open-test subset the original set was split in two subsets by speakers and synthesis models.
|

First, 2 out of the 6 available synthesis models were reserved exclusively for testing.
|
| 60 |
+
Additionally 20 % of the speakers were selected randomly from each accent and sex. The combination of both subsets generated the open-test subset.
