Prosodic modules for speech recognition and understanding in VERBMOBIL.
Within VERMOBIL, a large project on spoken language research in Germany, two modules for detecting and recognising prosodic events have been deveopled. One module operates on speech signal parameterss and the word hypothesis graph, whereas the other module, designed for a novel, highly interactive architecture, only uses speech signal parameters as its input. Phase boundaries, sentence modality, and accents are detected. The recognition rates in spontaneous dialogs are for accents up to 82.5%, for phase boundaries up to 91.7%.
