The EU project LISTEN ( is concerned with various aspects of far-field large-vocabulary speech recognition. As part of this project, we will organize a three-day workshop in Bonn/Germany, 17-19 July 2018 (Tuesday-Thursday).

The workshop intends to bring together experts from academic and industrial research in this fast developing area of speech recognition. The workshop will include regular talks and keynote talks. In total, we expect an audience of about 50 researchers.
