摘要翻译：
在这篇论文中，我们提出了一种机器学习的方法来校正卡拉OK环境中的人声和伴奏在不同的轨道上和时间对齐的声音的音高。该网络将两个音轨的时频表示作为输入，并预测使声音与伴奏合拍所需的音高移动量（以美分为单位）。它是在半专业歌唱的例子上训练的。该方法与现有的实时音高校正方法不同，它取代了音高跟踪和映射到一组离散的音符--例如12类等调音阶--而直接从声乐和伴奏音轨的谐波中学习一个在频率和时间上都连续的校正。递归神经网络(RNN)模型提供了考虑上下文的校正，保留了表达性的音高弯曲和颤音。这种方法可以扩展到声乐表演的无监督音高校正--通常称为自动调谐。

英文摘要：
  In this paper, we present a machine-learning approach to pitch correction for voice in a karaoke setting, where the vocals and accompaniment are on separate tracks and time-aligned. The network takes as input the time-frequency representation of the two tracks and predicts the amount of pitch-shifting in cents required to make the voice sound in-tune with the accompaniment. It is trained on examples of semi-professional singing. The proposed approach differs from existing real-time pitch correction methods by replacing pitch tracking and mapping to a discrete set of notes---for example, the twelve classes of the equal-tempered scale---with learning a correction that is continuous both in frequency and in time directly from the harmonics of the vocal and accompaniment tracks. A Recurrent Neural Network (RNN) model provides a correction that takes context into account, preserving expressive pitch bending and vibrato. This method can be extended into unsupervised pitch correction of a vocal performance---popularly referred to as autotuning.
