双语语音编辑数据集收录约4100万组样本

语音编辑不仅是把某句话中的词换掉，还可能需要在准确的位置加入笑声，或删去一次咳嗽。VoxCanvas-41M团队公开了一批双语训练数据，约含4100万组编辑样本。内容层面的任务包括修改一个片段、同时修改多个片段，以及依据位置提示完成编辑。另一类任务则针对笑声、叹息、咳嗽等39种非语言事件执行插入和删除。 Zhikang Niu等人的这项研究收录在11月6日更新的计算机科学预印本列表中。

研究者用这套数据训练了能按指令编辑语音的VoxCanvas-Edit，并考察模型先学会哪些操作、不同任务共同训练时如何相互影响，以及增加样本或改变训练策略后的表现。团队同时公开数据、构建流程及演示。对研究者而言，除了取得现成样本，还可以复用流程、拆开不同编辑任务比较，检验一种操作的改进是否也能迁移到另一种操作。
