论文摘要
本文提出了一个可控的唱歌语音合成系统，该系统能够通过两种新颖的方法产生表达性的歌声。首先，提出了一个本地样式的令牌模块，该模块可以从输入音调和文本序列预测帧级样式令牌，以允许唱歌语音系统控制音乐表达式在乐谱音乐中通常不指定（例如呼吸和强度）。其次，我们提出了一个双路径音高编码器，可以选择两个不同的音高输入：MIDI音高序列或F0轮廓。由于通常通过采用MIDI音高序列来执行歌声的初始一代，因此以后可以从生成的歌声中提取F0轮廓，并根据需要将F0轮廓修改为较优质的水平。通过定量和定性评估，我们确认了所提出的模型可以控制各种音乐表达式，同时又不牺牲Singing语音合成系统的声音质量。
This paper proposes a controllable singing voice synthesis system capable of generating expressive singing voice with two novel methodologies. First, a local style token module, which predicts frame-level style tokens from an input pitch and text sequence, is proposed to allow the singing voice system to control musical expression often unspecified in sheet music (e.g., breathing and intensity). Second, we propose a dual-path pitch encoder with a choice of two different pitch inputs: MIDI pitch sequence or f0 contour. Because the initial generation of a singing voice is usually executed by taking a MIDI pitch sequence, one can later extract an f0 contour from the generated singing voice and modify the f0 contour to a finer level as desired. Through quantitative and qualitative evaluations, we confirmed that the proposed model could control various musical expressions while not sacrificing the sound quality of the singing voice synthesis system.
