Unsupervised Neural Mask Estimator For Generalized Eigen-Value Beamforming Based ASR

28 Nov 2019Rohit KumarAnirudh SreeramAnurenjan PurushothamanSriram Ganapathy

The state-of-art methods for acoustic beamforming in multi-channel ASR are based on a neural mask estimator that predicts the presence of speech and noise. These models are trained using a paired corpus of clean and noisy recordings (teacher model)... (read more)
