We introduce the task of audio-visual scene-aware dialog (AVSD). In SAVD, an agent’s task is to answer in natural language questions about a short video. tl Scene-Aware Dialog (AVSD) Challenge at DSTC7 he agent grounds its responses on the dynamic scene, the audio, and the history (previous rounds) of the dialog.
