Python Wrapper for PESQ Score (narrow band and wide band)
PESQ (Perceptual Evaluation of Speech Quality) Wrapper for Python Users
This code is designed for numpy array specially.
gcc compiler numpy cython
Build and Install
$ git clone https://github.com/ludlows/python-pesq.git $ cd python-pesq $ pip install . # for python 2 $ pip3 install . # for python 3 $ cd .. $ rm -rf python-pesq # remove the code folder since it exists in the python package folder
Install with pip
$ pip install https://github.com/ludlows/python-pesq/archive/master.zip # or $ pip3 install https://github.com/ludlows/python-pesq/archive/master.zip
Example for narrow band and wide band
when using it, please note that the sampling rate (frequency) should be 16000 or 8000.
And using 8000 is supported for narrow band only.
from scipy.io import wavfile from pesq import pesq rate, ref = wavfile.read("./audio/speech.wav") rate, deg = wavfile.read("./audio/speech_bab_0dB.wav") print(pesq(rate, ref, deg, 'wb')) print(pesq(rate, ref, deg, 'nb'))
The correctness is verified by running samples in audio folder.
PESQ computed by this code in wide band mode is 1.0832337141036987
PESQ computed by this code in narrow band mode is 1.6072081327438354
Sampling rate (fs|rate) - No default. Must select either 8000Hz or 16000Hz.
Note there is narrow band (nb) mode only when sampling rate is 8000Hz.
The original C soure code is modified.
