About the conference

The SLT Workshop is a biennial flagship event of IEEE Speech and Language Processing Technical Committee. The 8th IEEE Spoken Language Technology Workshop (SLT 2021) will be held on January 19-22, 2021 in Shenzhen, China.

Deep learning has witnessed great success in spoken language technologies over the last decade. We continue welcoming research work from this area. The main theme for SLT 2021 will be around "Spoken language technologies: deep learning and beyond". Besides deep learning, we also encourage explorative efforts on new paradigms and forward-looking approaches for the advancement of spoken language technologies.


The workshop program will keep the successful format of previous SLTs and will feature invited talks/keynotes, regular papers and special sessions. All papers will be presented as posters. A full social program will provide ample opportunities for discussion, including welcome reception, banquet, lunches, etc.

Topics of interest include, but not limited to, the following,

  • Speech recognition and synthesis
  • Spoken language understanding
  • Spoken document retrieval
  • Question answering from speech
  • Assistive technologies
  • Natural language processing
  • Multimodal processing
  • Human/computer interaction
  • Spoken dialog systems
  • Speech data mining
  • Emotion recognition from speech
  • Spoken document summarization
