简介

SepFormer WHAMR 是一款由 SpeechBrain 团队开发的语音增强模型，专注于从嘈杂的背景环境中提取纯净的人声。它采用了先进的 Transformer 架构来处理频谱分离，特别擅长处理复杂的真实场景噪声（如街道、餐厅等）。对于开发者而言，该模型提供了极高的工程实用性，能够显著提升语音识别（ASR）的前端预处理质量，将低信噪比的音频转化为高清晰度语音，上手难度中等，可无缝集成到基于 PyTorch 的语音处理流水线中。

核心亮点

  • 基于 SepFormer 架构，强力去除复杂环境噪声
  • 大幅提升 ASR 语音识别系统的前端输入质量
  • 开源 Apache-2.0 协议，方便商业化快速部署
  • 适配 SpeechBrain 框架，支持灵活的端到端调用

SepFormer trained on WHAMR! for speech enhancement (8k sampling frequency)

This repository provides all the necessary tools to perform speech enhancement (denoising + dereverberation) with a SepFormer model, implemented with SpeechBrain, and pretrained on WHAMR! dataset with 8k sampling frequency, which is basically a version of WSJ0-Mix dataset with environmental noise and reverberation in 8k. For a better experience we encourage you to learn more about SpeechBrain. The given model performance is 10.59 dB SI-SNR on the test set of WHAMR! dataset.

Install SpeechBrain

First of all, please install SpeechBrain with the following command:

code
pip install speechbrain

Please notice that we encourage you to read our tutorials and learn more about SpeechBrain.

Perform speech enhancement on your own audio file

python
from speechbrain.inference.separation import SepformerSeparation as separator
import torchaudio

model = separator.from_hparams(source="speechbrain/sepformer-whamr-enhancement", savedir='pretrained_models/sepformer-whamr-enhancement')


for custom file, change path

est_sources = model.separate_file(path='speechbrain/sepformer-whamr-enhancement/example_whamr.wav')

torchaudio.save("enhanced_whamr.wav", est_sources[:, :, 0].detach().cpu(), 8000)

Inference on GPU

To perform inference on the GPU, add run_opts={"device":"cuda"} when calling the from_hparams method.

Training

The training script is currently being worked on an ongoing pull-request.

We will update the model card as soon as the PR is merged.

You can find our training results (models, logs, etc) here.

Limitations

The SpeechBrain team does not provide any warranty on the performance achieved by this model when used on other datasets.
