  Monaural singing voice separation task focuses on the prediction of the
singing voice from a single channel music mixture signal. Current state of the
art (SOTA) results in monaural singing voice separation are obtained with deep
learning based methods. In this work we present a novel deep learning based
method that learns long-term temporal patterns and structures of a musical
piece. We build upon the recently proposed Masker-Denoiser (MaD) architecture
and we enhance it with the Twin Networks, a technique to regularize a recurrent
generative network using a backward running copy of the network. We evaluate
our method using the Demixing Secret Dataset and we obtain an increment to
signal-to-distortion ratio (SDR) of 0.37 dB and to signal-to-interference ratio
(SIR) of 0.23 dB, compared to previous SOTA results.
