Voice activity detection (VAD) and speech enhancement (SE) are important front-end technologies for noise robust speech recognition system.
From incoming noisy signal, VAD detects the speech signal only and SE removes the noise signal while conserving the speech signal.
For VAD and SE, this presentation will cover the traditional methods, deep learning based methods, and our papers as follows:
1. J. Kim and M. Hahn, "Voice Activity Detection Using an Adaptive Context Attention Model," in IEEE Signal Processing Letters, vol. 25, no. 8, pp. 1181-1185, Aug. 2018.
2. J. Kim and M. Hahn, "Speech Enhancement Using a Two Step Network," submitted to IEEE Signal Processing Letters, 2018.
Also, this presentation will briefly introduce some experimental results in real-world environment (far-field, noisy environment), conducted on the embedded board.
For VAD,
