3. First, let us remark that less than one third of the scores denoted uncertainty (see Fig. 3a), which means that the differences between methods were audible most of the time. There seem to be a clear preference for short analysis windows for the female voice and a less clear preference for longer windows for the male voice. However, the variability of the scores made confidence intervals larger than desirable. Although this could be seen as a symptom of inconsistent individual scoring, this was not the case.

Firstly, an overview of a TTS system is depicted in Section 2. Then, TTS systems, both HMM-based and DNN-based, are described in Section 3. Next, results on the objective evaluation with both TTS systems are reported in Section 4. Finally, concluding remarks and future research lines are wrapped up in Section 5. 2 System Overview In Figure 1 we provide an overview of the modules that make up our TTS system. We describe the modules involved in our system from the moment the subtitle file is received to the point the speech output is ready to be embedded.
