摘要翻译：
将深度学习应用于音乐处理的一个主要挑战是训练数据的可用性。一个潜在的解决方案是多任务学习，其中模型还学习解决额外数据集上的相关辅助任务，以利用它们的相关性。虽然原则上是直观的，但识别相关任务并构造模型以在任务之间最优地共享信息可能是一个挑战。在这篇论文中，我们探索声乐活动检测作为一个额外的任务，以稳定和提高声乐分离的性能。此外，我们识别了每个数据集特有的有问题的偏差，这些偏差可能会限制分离和检测模型的推广能力，对此我们提出的方法是鲁棒的。实验表明，与单一任务基线相比，在分离和声音检测方面的性能有所改善。然而，我们发现常用的信号失真比(SDR)指标没有捕捉到非发声部分的改善，这表明需要改进评估方法。

英文摘要：
  A main challenge in applying deep learning to music processing is the availability of training data. One potential solution is Multi-task Learning, in which the model also learns to solve related auxiliary tasks on additional datasets to exploit their correlation. While intuitive in principle, it can be challenging to identify related tasks and construct the model to optimally share information between tasks. In this paper, we explore vocal activity detection as an additional task to stabilise and improve the performance of vocal separation. Further, we identify problematic biases specific to each dataset that could limit the generalisation capability of separation and detection models, to which our proposed approach is robust. Experiments show improved performance in separation as well as vocal detection compared to single-task baselines. However, we find that the commonly used Signal-to-Distortion Ratio (SDR) metrics did not capture the improvement on non-vocal sections, indicating the need for improved evaluation methodologies.
