Dear colleagues,

It is our pleasure to invite you to participate in the 12th International Workshop on Spoken Dialog System Technology (IWSDS 2021). This year’s conference theme will be:

“Conversational AI for natural human-centric interaction”

Following the success of a series of eleven previous events, the 12th International Workshop on Spoken Dialog System Technology (IWSDS 2021) will be held on 15-17 November 2021 in Singapore. Participants will be able to keep track of the state of the art in spoken dialogue systems while enjoying the year-round summer paradise island that is Singapore.

IWSDS 2021 will be held virtually in view of the current situation. Authors will present their work and interact with participants virtually.

On behalf of the organizing committee, we welcome you to Singapore, and hope that you enjoy the workshop as well as the glorious mix of cultures and traditions on display.

Haizhou Li (National University of Singapore)

IWSDS 2021 General Chair
