Contents of this repository

This repository is organized into three main components: ClearVoice, Train, and SpeechScore.

1. ClearVoice

ClearVoice offers a user-friendly solution for speech processing tasks such as speech denoising, separation, audio-visual target speaker extraction, and more. It is designed as a unified inference platform leveraged pre-trained models (e.g., FRCRN, MossFormer), all trained on extensive datasets. If you're looking for a tool to improve speech quality, ClearVoice is the perfect choice. Simply click on ClearVoice and follow our detailed instructions to get started.

2. Train

For advanced researchers and developers, we provide model finetune and training scripts for all the tasks offerred in ClearVoice and more:

• Task 1: Speech enhancement (16kHz & 48kHz)
• Task 2: Speech separation (8kHz & 16kHz)
• Task 3: Target speaker extraction
  • Sub-Task 1: Audio-only Speaker Extraction Conditioned on a Reference Speech (8kHz)
  • Sub-Task 2: Audio-visual Speaker Extraction Conditioned on Face (Lip) Recording (16kHz)
  • Sub-Task 3: Audio-visual Speaker Extraction Conditioned on Body Gestures (16kHz)
  • Sub-Task 4: Neuro-steered Speaker Extraction Conditioned on EEG Signals (16kHz)

Contributors are welcomed to include more model architectures and tasks!

3. SpeechScore

SpeechScore is a speech quality assessment toolkit. We include it here to evaluate different model performance. SpeechScore includes many popular speech metrics:

• Signal-to-Noise Ratio (SNR)
• Perceptual Evaluation of Speech Quality (PESQ)
• Short-Time Objective Intelligibility (STOI)
• Deep Noise Suppression Mean Opinion Score (DNSMOS)
• Scale-Invariant Signal-to-Distortion Ratio (SI-SDR)
• and many more quality benchmarks
