“…We newly captured speech scenes of two persons, X and Y (the same persons in the training data), and segmented them into interval sequences 1 According to the research on the over all timing tolerance between video and audio by A. Peregudov et al [13], the thresholds of acceptability are about +90 ms (sound leading) to −185 ms (sound delayed). For these reason, we decided the standard deviation of the Gaussian, σ, as 2σ 100 ms ( the frame rate was 60 fps, therefore σ = 3 frames 50 ms ).…”
