摘要:

我们建议使用自监督离散表示的语音再合成的任务。为了生成解纠缠表示,我们分别提取语音内容,韵律信息和扬声器身份的低比特率表示。这允许以可控的方式合成语音。我们分析了各种最先进的,自我监督的表示学习方法,并阐明了每种方法的优点,同时考虑重建质量和解纠缠属性。具体来说,我们评估的F0重建,说话人辨识性能(重新合成和语音转换),录音的可懂度,和整体质量使用主观的人的评价。最后,我们演示了如何将这些表示用于超轻量语音编解码器。使用获得的表示,我们可以得到每秒365比特的速率,同时提供比基线方法更好的语音质量。音频样本可以在以下链接中找到:speechbot.github.io/resynthesis。

英文摘要:

We propose using self-supervised discrete representations for the task of speech resynthesis. To generate disentangled representation, we separately extract low-bitrate representations for speech content, prosodic information, and speaker identity. This allows to synthesize speech in a controllable manner. We analyze various state-of-the-art, self-supervised representation learning methods and shed light on the advantages of each method while considering reconstruction quality and disentanglement properties. Specifically, we evaluate the F0 reconstruction, speaker identification performance (for both resynthesis and voice conversion), recordings' intelligibility, and overall quality using subjective human evaluation. Lastly, we demonstrate how these representations can be used for an ultra-lightweight speech codec. Using the obtained representations, we can get to a rate of 365 bits per second while providing better speech quality than the baseline methods. Audio samples can be found under the following link: speechbot.github.io/resynthesis.
