The research carried out in the Spoken Language Processing Group aims to understand the speech communication processes and to develop models for use in automatic speech processing. Research in speech recognition is oriented towards continuous speech transcription of spontaneous speech in multiple languages, the identification of non-linguistic speech features, and spoken language understanding. Advances in speech recognition are based on research carried out in acoustic-phonetic modeling , lexical modeling and language modeling. Combining natural language processing and spontaneous speech recognition, spoken language understanding systems are being developed for information retrieval.
Dialog management plays a central role in spoken language systems.
