摘要:

语音增强技术近年来取得了很大的进步,主要是通过去噪,说话人分离和去混响方法,主要是处理环境对声乐音频的影响。为了增强语音超出原始信号的限制,我们采取再生的方法,其中我们从语音的本质,包括半识别的语音,韵律特征,和身份重新创建的语音。我们提出了一个波到波的语音生成模型,可以生成24位语音在一个实时的方式,并利用一个紧凑的语音表示,组成的ASR和身份特征,以实现更高水平的可理解性。受语音转换方法的启发,我们进行训练以增强语音特征,同时使用辅助身份网络来保留源的身份。感知声学指标和主观测试表明,该方法获得了宝贵的改进,最近的基线。

英文摘要:

Speech enhancement has seen great improvement in recent years mainly through contributions in denoising, speaker separation, and dereverberation methods that mostly deal with environmental effects on vocal audio. To enhance speech beyond the limitations of the original signal, we take a regeneration approach, in which we recreate the speech from its essence, including the semi-recognized speech, prosody features, and identity. We propose a wav-to-wav generative model for speech that can generate 24khz speech in a real-time manner and which utilizes a compact speech representation, composed of ASR and identity features, to achieve a higher level of intelligibility. Inspired by voice conversion methods, we train to augment the speech characteristics while preserving the identity of the source using an auxiliary identity network. Perceptual acoustic metrics and subjective tests show that the method obtains valuable improvements over recent baselines.
