Welcome to the chair of Junior Professorship Computational Linguistics at IMS Stuttgart. The group has been headed by Junior-Prof. Ngoc Thang Vu since October 2015.
We conduct research on the following research areas:
- Speech Understanding, e.g.
- Automatic Speech Recognition
- Interface between Speech Recognition and Natural Language Understanding
- Representation Learning for Words, Phrases and Utterances
- Signals Encoded in Speech and their Roles for Understanding, e.g.
- Linguistics, e.g. Prosody
- Paralinguistics, e.g. Emotion
- Spoken Dialogue Systems, e.g.
- Speaker Intention
- Dialogue Manager
