| Abstract |
Deep neural networks (DNNs) have been applied successfully to music information retrieval (MIR). In this paper, we design a convolutional recurrent neural network (CRNN) for automatic singing quality evaluation, and present a comparative study over various acoustic features as network input. We optimize the CRNN so that the machine-predicted scores are closer to the human-annotated scores. Furthermore, we augment spectral features with pitch histogram (a musically-motivated representation) as network input. The experiments show that our proposed CRNN framework can learn the underlying discerning properties of singing quality effectively. Moreover, explicit incorporation of pitch histogram further improves system performance, and reduces the system’s dependency on song content. |
