摘要:

语音克隆是个性化语音界面的一个非常需要的功能。基于神经网络的语音合成已被证明可以为大量说话者生成高质量的语音。在本文中,我们介绍了一个神经语音克隆系统,需要一些音频样本作为输入。我们研究了两种方法:说话人自适应和说话人编码。说话人自适应是基于微调的多说话人生成模型与一些克隆样本。说话人编码是基于训练一个单独的模型来直接从克隆音频中推断出一个新的说话人嵌入,并与多说话人生成模型一起使用。在语音的自然度和与原说话人的相似度方面,这两种方法都可以达到很好的性能,即使克隆音频很少。虽然说话人自适应可以实现更好的自然度和相似性,但说话人编码方法的克隆时间或所需内存显着减少,使其有利于低资源部署。

英文摘要:

Voice cloning is a highly desired feature for personalized speech interfaces. Neural network based speech synthesis has been shown to generate high quality speech for a large number of speakers. In this paper, we introduce a neural voice cloning system that takes a few audio samples as input. We study two approaches: speaker adaptation and speaker encoding. Speaker adaptation is based on fine-tuning a multi-speaker generative model with a few cloning samples. Speaker encoding is based on training a separate model to directly infer a new speaker embedding from cloning audios and to be used with a multi-speaker generative model. In terms of naturalness of the speech and its similarity to original speaker, both approaches can achieve good performance, even with very few cloning audios. While speaker adaptation can achieve better naturalness and similarity, the cloning time or required memory for the speaker encoding approach is significantly less, making it favorable for low-resource deployment.
