Query: Comparison for Improvements of Singing Voice Detection System Based on
  Vocal Separation   Singing voice detection is the task to identify the frames which contain the
singer vocal or not. It has been one of the main components in music
information retrieval (MIR), which can be applicable to melody extraction,
artist recognition, and music discovery in popular music. Although there are
several methods which have been proposed, a more robust and more complete
system is desired to improve the detection performance. In this paper, our
motivation is to provide an extensive comparison in different stages of singing
voice detection. Based on the analysis a novel method was proposed to build a
more efficiently singing voice detection system. In the proposed system, there
are main three parts. The first is a pre-process of singing voice separation to
extract the vocal without the music. The improvements of several singing voice
separation methods were compared to decide the best one which is integrated to
singing voice detection system. And the second is a deep neural network based
classifier to identify the given frames. Different deep models for
classification were also compared. The last one is a post-process to filter out
the anomaly frame on the prediction result of the classifier. The median filter
and Hidden Markov Model (HMM) based filter as the post process were compared.
Through the step by step module extension, the different methods were compared
and analyzed. Finally, classification performance on two public datasets
indicates that the proposed approach which based on the Long-term Recurrent
Convolutional Networks (LRCN) model is a promising alternative.
