Query: Voice activity detection in the wild via weakly supervised sound event
  detection   Traditional supervised voice activity detection (VAD) methods work well in
clean and controlled scenarios, with performance severely degrading in
real-world applications. One possible bottleneck is that speech in the wild
contains unpredictable noise types, hence frame-level label prediction is
difficult, which is required for traditional supervised VAD training. In
contrast, we propose a general-purpose VAD (GPVAD) framework, which can be
easily trained from noisy data in a weakly supervised fashion, requiring only
clip-level labels. We proposed two GPVAD models, one full (GPV-F), trained on
527 Audioset sound events, and one binary (GPV-B), only distinguishing speech
and noise. We evaluate the two GPV models against a CRNN based standard VAD
model (VAD-C) on three different evaluation protocols (clean, synthetic noise,
real data). Results show that our proposed GPV-F demonstrates competitive
performance in clean and synthetic scenarios compared to traditional VAD-C.
Further, in real-world evaluation, GPV-F largely outperforms VAD-C in terms of
frame-level evaluation metrics as well as segment-level ones. With a much lower
requirement for frame-labeled data, the naive binary clip-level GPV-B model can
still achieve comparable performance to VAD-C in real-world scenarios.
