The ESCA Workshop on Speech Synthesis
September 25-28, 1990
The linguistic processing of the CNET's Text-to-Speech (TTS) synthesis for German has recently been automatized and extended by a series of new algorithms. The modifications concern the following three stages: first, a preprocessing stage was added to convert numerical expressions, abbreviations and diacritics into sequences of graphemes. Then, the morphological analysis has been extended to compound words - one of the major problems of German morphology - and to the grammatical labelling of word classes. Finally, an automatic parser has been developed for the insertion of syntactic-prosodic markers. It uses a set of hierarchized parsing rules which are applied to the extracted sequences of grammatical categories resulting from the upper analysis.
