In this work, we tackle the challenge of enhancing the realism and
expressiveness in talking head video generation by focusing on the dynamic and
nuanced relationship between audio cues and facial movements. We identify the
limitations of traditional techniques that often fail to capture the full
spectrum of human expressions and the uniqueness of individual facial styles.
To address these issues, we propose EMO, a novel framework that utilizes a
direct audio-to-video synthesis approach, bypassing the need for intermediate
3D models or facial landmarks. Our method ensures seamless frame transitions
and consistent identity preservation throughout the video, resulting in highly
expressive and lifelike animations. Experimental results demonsrate that EMO is
able to produce not only convincing speaking videos but also singing videos in
various styles, significantly outperforming existing state-of-the-art
methodologies in terms of expressiveness and realism.

在这项工作中，我们通过关注音频线索和面部动作之间的动态和微妙关系，解决了提高说话视频生成中的真实感和表现力的挑战。我们确定了传统技术的局限性，常常无法捕捉到人类表情的全谱和个体面部风格的独特性。为了解决这些问题，我们提出了 EMO，这是一个新颖的框架，利用直接的音频到视频合成方法，绕过了中间的 3D 模型或面部标记的需求。我们的方法确保了平滑的帧过渡和在整个视频中的一致身份保护，从而产生高度表现力和逼真的动画。实验结果表明，EMO 不仅能够产生令人信服的说话视频，还能以各种风格生成唱歌视频，其在表现力和逼真度方面明显优于现有最先进的方法学。
