+[![DOI](https://zenodo.org/badge/220233987.svg)](https://zenodo.org/badge/latestdoi/220233987)
+
+Python implementation of objective quality and intelligibilty measures mentioned in Philipos C. Loizou's great [Speech Enhancement Book](https://www.crcpress.com/Speech-Enhancement-Theory-and-Practice-Second-Edition/Loizou/p/book/9781138075573). The Python implementations are checked with the MATLAB implementations attached to the book (see [Link](https://crcpress.com/downloads/K14513/K14513_CD_Files.zip))
+
+# Install with pip
+Install pysepm:
+```
+pip3 install https://github.com/schmiph2/pysepm/archive/master.zip
+```
+# Examples
+Please find a Jupyter Notebook with examples for all implemented measures in the [examples folder](https://github.com/schmiph2/pysepm/tree/master/examples).
+
+# Implemented Measures
+## Speech Quality Measures
++ Segmental Signal-to-Noise Ratio (SNRseg)
++ Frequency-weighted Segmental SNR (fwSNRseg)
++ Log-likelihood Ratio (LLR)
++ Weighted Spectral Slope (WSS)
++ Perceptual Evaluation of Speech Quality (PESQ), ([python-pesq](https://github.com/ludlows/python-pesq) implementation by ludlows)
++ Composite Objective Speech Quality (composite)
++ Cepstrum Distance Objective Speech Quality Measure (CD)
+
+## Speech Intelligibility Measures
++ Short-time objective intelligibility (STOI), ([pystoi](https://github.com/mpariente/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)
