Python bindings of speexdsp noise suppression library
Modified from https://github.com/xiongyihui/speexdsp-python
You can use it in Noise reduction model training as said in Personalized PercepNet: Real-time, Low-complexity Target Voice Separation and Enhancement.
Use a VAD and lightweight denoiser (SpeexDSP1) to eliminate the stationary noise before using this data for training.
Requirements
- swig
- compile toolchain
- python
- libspeexdsp-dev
Build
sudo apt install libspeexdsp-dev
sudo apt install swig
python setup.py install
