| Research Abstract |
The increasing availability of large speech databases makes it possible to construct speech synthesis systems, which are referred to as data-driven or corpus-based approach, by applying statistical learning algorithms. These systems, which can be automatically trained, not only generate natural and high quality synthetic speech but also can reproduce voice characteristics of the original speaker. However, to make the whole voice building process fully-automatic, we need to construct speech databases in an automatic way. In this research work, we investigate automatic voice building techniques for an HMM-based speech synthesis system which can synthesize speech with various voice qualities. First, we implemented an GUI-based labeling tool, called PLEd (Prosody and Linguistic Label Editor). Then, in order to construct an automatic voice building system, we have developed an automatic accent labeling technique. It has been shown that by using the developed system, we have successfully label accent information.
