Junior Professorship Computational Linguistics

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 three following research areas:

  1. Methods for Speech Understanding:
    1. Automatic Speech Recognition
    2. Interface between Speech Recognition and Natural Language Understanding
    3. Representation Learning for Words, Phrases and Utterances
  2. Signals Encoded in Speech and their Roles for Understanding:
    1. Prosody
    2. Emotion
  3. Applications:
    1. Neural-based Dialog Systems
    2. Spoken Dialog Summarization
