VoiceRestore: Flow-Matching Transformers for Speech Recording Quality Restoration

VoiceRestore is a cutting-edge speech restoration model designed to significantly enhance the quality of degraded voice recordings. Leveraging flow-matching transformers, this model excels at addressing a wide range of audio imperfections commonly found in speech, including background noise, reverberation, distortion, and signal loss.

It is based on this repo & demo of audio restorations: VoiceRestore

Usage - using Transformers 🤗

!git lfs install
!git clone https://huggingface.co/jadechoghari/VoiceRestore
%cd VoiceRestore
!pip install -r requirements.txt

from transformers import AutoModel
# path to the model folder (on colab it's as follows)
checkpoint_path = "/content/VoiceRestore"
model = AutoModel.from_pretrained(checkpoint_path, trust_remote_code=True)
model("test_input.wav", "test_output.wav")
#add short=False if audio is > 10 seconds
model("long.mp3", "long_output.mp3", short=False)

Key Features

• Universal Restoration: The model can handle any level and type of voice recording degradation. Pure magic.
• Easy to Use: Simple interface for processing degraded audio files.
• Pretrained Model: Includes a 301 million parameter transformer model with pre-trained weights. (Model is still in the process of training, there will be further checkpoint updates)

Model Details

• Architecture: Flow-matching transformer
• Parameters: 300M+ parameters
• Input: Degraded speech audio (various formats supported)
• Output: Restored speech

Limitations and Future Work

• Current model is optimized for speech; may not perform optimally on music or other audio types.
• Ongoing research to improve performance on extreme degradations.
• Future updates may include real-time processing capabilities.
