摘要:

音乐作为一种情感干预媒介,在音乐治疗、游戏和电影等场景中具有重要应用。然而,由于目标情感的细粒度和多变性,音乐需要根据不断变化的情感进行实时编曲,这给平衡情感实时匹配和软情感过渡带来了挑战。现有研究主要集中在实现情感实时匹配上,而平滑过渡问题仍未得到充分研究,影响了音乐的整体情感连贯性。在本文中,我们提出REMAST来解决这一权衡问题。具体而言,我们识别上一时间步的音乐情感,并将其与当前时间步的输入情感进行融合。融合后的情感随后指导REMAST基于输入旋律生成音乐。为了灵活调整音乐相似度和情感实时匹配,我们对原始旋律进行下采样并将其输入生成模型。此外,我们利用领域知识设计了四种音乐理论特征以增强情感信息,并采用半监督学习来减轻人工数据集标注引入的主观偏差。根据评估结果,REMAST在客观和主观指标上均超越了现有最先进方法。这些结果表明,REMAST同时实现了实时匹配和平滑过渡,增强了生成音乐的连贯性。

英文摘要:

Music as an emotional intervention medium has important applications in scenarios such as music therapy, games, and movies. However, music needs real-time arrangement according to changing emotions, bringing challenges to balance emotion real-time fit and soft emotion transition due to the fine-grained and mutable nature of the target emotion. Existing studies mainly focus on achieving emotion real-time fit, while the issue of smooth transition remains understudied, affecting the overall emotional coherence of the music. In this paper, we propose REMAST to address this trade-off. Specifically, we recognize the last timestep's music emotion and fuse it with the current timestep's input emotion. The fused emotion then guides REMAST to generate the music based on the input melody. To adjust music similarity and emotion real-time fit flexibly, we downsample the original melody and feed it into the generation model. Furthermore, we design four music theory features by domain knowledge to enhance emotion information and employ semi-supervised learning to mitigate the subjective bias introduced by manual dataset annotation. According to the evaluation results, REMAST surpasses the state-of-the-art methods in objective and subjective metrics. These results demonstrate that REMAST achieves real-time fit and smooth transition simultaneously, enhancing the coherence of the generated music.
