\nAbstract: <\/strong><\/p>\n

The objective of this thesis is the generation of a high quality expressive audio-book, using natural and synthetic speech signals with a minimal recording cost.<\/p>\n

The strategy consists on selecting a part of the book and recording its reading to build a voice corpus. This voice is then used for synthesizing the rest of the book using a Text-to-Speech system. Several strategies are successively proposed: a posterior approach using voice reduction methods, a neural network based (CNN) auto-encoder focusing on linguistic information, and then the selection of the shortest utterances. These different approaches are objectively and perceptually evaluated.<\/p>\n

Finally, the quality of audio-book mixing natural and synthetic speech signals is evaluated. The evaluations show the mixture of synthetic and natural signals is preferred than fully synthetic signals produced by a unit selection based TTS system.<\/p>\n
