The 22nd Annual Meeting of the Special Interest Group on Discourse and Dialogue (SIGDIAL 2021) will be held on 29-31 July 2021 in Singapore.

The SIGDIAL venue provides a regular forum for the presentation of cutting edge research in discourse and dialogue to both academic and industry researchers. Continuing a series of nineteen successful previous meetings, this conference spans the research interest areas of discourse and dialogue. The conference is sponsored by the SIGdial organization, which serves as the Special Interest Group in discourse and dialogue for both ACL and ISCA.

SIGDIAL 2021 is preparing for a hybrid in-person and virtual conference where people can participate online if they want. In view of the COVID-19 situation, we expect that most international participants will join the conference remotely, while the local participants join physically. Updated information on Singapore’s border control measures in response to COVID-19 can be found on the ICA website. Information on the SG Arrival Card with Electronic Health Declaration can be found here

We thank you for your support and look forward to welcoming you at the conference. Stay safe and healthy!
