# Speech Enhancement Metrics

This implementation of Matlab was originally taken from [https://ecs.utdallas.edu/loizou/speech/software.htm](https://ecs.utdallas.edu/loizou/speech/software.htm)

## REQUIREMENTS

Octave must be installed

```bash

apt install octave

pip install oct2py Cython # install Cython before installing pesq

pip install pesq

```

## COMPOSITE MEASURE

Usage:

```matlab

[Csig,Cbak,Covl,segSNR]=composite(cleanfile.wav,enhanced.wav)

```

where ```Csig``` is the predicted rating of speech distortion, ```Cbak``` is the predicted rating of background distortion, ```Covl``` is the predicted rating of overall quality.

You may run example files included in the zip file. In MATLAB, type:

```matlab

>> [c,b,o,s]=composite('sp09.wav','enhanced_logmmse.wav')

c = 3.3050

b = 2.6160

o = 2.7133

s = 3.9917

```

where ```sp09.wav``` is the clean file and ```enhanced_logmmse.wav``` is the enhanced file.
