Development of an automatic speech synthesis system from standard vowelized Arabic text.

Summary The work of this thesis is a contribution to the study and development of a speech synthesis system from vowelized standard Arabic text based on the diphone. This contribution intervenes at different levels of this system: construction of the acoustic base, syntactic analysis, grapheme-phoneme conversion and prosody generation. The implemented morpho-syntactic analysis is based on the use of a partial lexicon, default labeling and the propagation of contextual deductions. It allows the splitting of the text into non-recursive sections (intermediate between word and sentence). The syntax-prosody interface then distributes the pauses and generates the prosodic parameters of pitch and duration. All of this processing is integrated into the multilingual text-to-speech system from Elan Speech.
