Although user-friendly, such approaches are on one hand constrained: control is limited to acoustic features exposed to the model during training, and too flexible on the other: the same inputs yields uncontrollable variation that are reflected in the corpus statistics.\n  We investigate a novel fine-tuning regime to address both of these issues at the same time by exploiting the uncontrollable variance of the model.
