What is ClearerVoice-Studio?

ClearerVoice-Studio is an open-source speech processing framework from Alibaba DAMO Academy's Tongyi Lab, integrating functions such as speech enhancement, separation, and audio/video speaker extraction. Based on complex domain deep learning algorithms, the framework effectively eliminates background noise, preserves speech intelligibility, and minimizes speech distortion. ClearerVoice-Studio provides advanced pre-trained models and training scripts to support researchers and developers in performing speech processing tasks, promoting innovative applications of speech processing technology.

Main functions of ClearerVoice-Studio

  • Speech enhancementRemove background noise and improve the quality of the speech signal.
  • Speech separation: Extract the speech of the target speaker from mixed audio.
  • Target speaker extraction: Accurately extract the speech signal of a specific speaker from audio and video.
  • Model training and tuningIt provides tools and scripts that allow users to train and optimize models based on their own data.

The technical principles of ClearerVoice-Studio

  • Deep learning algorithms for complex fieldsBased on the advantages of signal processing in the complex field representation, it can effectively process and analyze speech signals.
  • Advanced model architecture:
    • FRCRN modelExceptional voice enhancement capabilities.
    • MossFormer series modelsIt outperforms traditional models in speech separation tasks and has been extended to speech enhancement and target speaker extraction tasks.
  • Multimodal processing capabilitySpeaker extraction is performed by combining audio and video information to improve the accuracy of recognition.
  • pre-trained modelThe model is pre-trained on a large-scale, high-quality dataset to ensure its effectiveness and generalization ability in different scenarios.
  • Flexible interface designProvides an easy-to-use interface.
