pysepm-evo - Python Speech Enhancement Performance Measures (Quality and Intelligibility)

DOI

PyPI released version of pysepm. Please note that this package doesn't include the usage pf pesq. To use SRMRpy, type the following:

pip install https://github.com/jfsantos/SRMRpy/archive/master.zip#egg=SRMRpy

Install with pip

Install pysepm-evo:

pip3 install pyseqm-evo

Examples

Please find a Jupyter Notebook with examples for all implemented measures in the examples folder.

Implemented Measures

Speech Quality Measures

  • Segmental Signal-to-Noise Ratio (SNRseg)
  • Frequency-weighted Segmental SNR (fwSNRseg)
  • Log-likelihood Ratio (LLR)
  • Weighted Spectral Slope (WSS) implementation by ludlows)
  • Composite Objective Speech Quality (composite)
  • Cepstrum Distance Objective Speech Quality Measure (CD)

Speech Intelligibility Measures

  • Short-time objective intelligibility (STOI), (pystoi implementation by mpariente)
  • Coherence and speech intelligibility index (CSII)
  • Normalized-covariance measure (NCM)

Dereverberation Measures (TODO)

  • Bark spectral distortion (BSD)
  • Scale-invariant signal to distortion ratio (SI-SDR)
