Formerly SISDIAL. Since 2005.
Since 2005, DELTA has researched how machines converse with people. Twenty-one years of work under a new name, with one decision that explains it all: working where the industry does not go.

Our impact
Twenty-one years working where the industry does not go.
We are a small group because we specialise in one thing only: machines that converse with real people. We go with rigour, through European projects, peer review and international collaboration, and come back with something people use.
