Automatic detection of syllable boundaries in spontaneous speech

International audienceThis paper presents the outline and performance of an automatic syllable boundary detection system. The syllabification of phonemes is performed with a rule-based system, implemented in a Java program. Phonemes are categorized into 6 classes and specific rules are developed to deal with a French spontaneous speech corpus. Moreover, the proposed phonemes, classes and rules are listed in an external configuration file of the tool (under GPL licence). Finally, performances are evaluated and compared to state-of-the-art systems and show significant improvements
