模型:
speechbrain/sepformer-libri3mix
该存储库提供了使用SpeechBrain实现的 SepFormer 模型在Libri3Mix数据集上进行音频源分离的所有必要工具。为了获得更好的体验,我们鼓励您了解 SpeechBrain 的更多信息。模型在Libri3Mix数据集的测试集上的性能为19.8 dB SI-SNRi。
Release | Test-Set SI-SNRi | Test-Set SDRi |
---|---|---|
16-09-22 | 19.0dB | 19.4dB |
首先,请使用以下命令安装SpeechBrain:
pip install speechbrain
请注意,我们鼓励您阅读我们的教程并了解 SpeechBrain 的更多信息。
from speechbrain.pretrained import SepformerSeparation as separator import torchaudio model = separator.from_hparams(source="speechbrain/sepformer-libri3mix", savedir='pretrained_models/sepformer-libri3mix') est_sources = model.separate_file(path='speechbrain/sepformer-wsj03mix/test_mixture_3spks.wav') torchaudio.save("source1hat.wav", est_sources[:, :, 0].detach().cpu(), 8000) torchaudio.save("source2hat.wav", est_sources[:, :, 1].detach().cpu(), 8000) torchaudio.save("source3hat.wav", est_sources[:, :, 2].detach().cpu(), 8000)
该系统期望输入的录音采样率为8kHz(单声道)。如果您的信号具有不同的采样率,请在使用界面之前对其进行重新采样(例如,使用torchaudio或sox)。
要在GPU上执行推断,请在调用from_hparams方法时添加run_opts={"device":"cuda"}。
该模型是使用SpeechBrain(fc2eabb7)训练的。要从头开始训练,请按照以下步骤操作:
git clone https://github.com/speechbrain/speechbrain/
cd speechbrain pip install -r requirements.txt pip install -e .
cd recipes/LibriMix/separation python train.py hparams/sepformer.yaml --data_folder=your_data_folder
注意:在yaml文件中将num_spks更改为3。
您可以在 here 找到我们的训练结果(模型、日志等)。
