Query: Advances in Online Audio-Visual Meeting Transcription   This paper describes a system that generates speaker-annotated transcripts of
meetings by using a microphone array and a 360-degree camera. The hallmark of
the system is its ability to handle overlapped speech, which has been an
unsolved problem in realistic settings for over a decade. We show that this
problem can be addressed by using a continuous speech separation approach. In
addition, we describe an online audio-visual speaker diarization method that
leverages face tracking and identification, sound source localization, speaker
identification, and, if available, prior speaker information for robustness to
various real world challenges. All components are integrated in a meeting
transcription framework called SRD, which stands for "separate, recognize, and
diarize". Experimental results using recordings of natural meetings involving
up to 11 attendees are reported. The continuous speech separation improves a
word error rate (WER) by 16.1% compared with a highly tuned beamformer. When a
complete list of meeting attendees is available, the discrepancy between WER
and speaker-attributed WER is only 1.0%, indicating accurate word-to-speaker
association. This increases marginally to 1.6% when 50% of the attendees are
unknown to the system.
