Speech Quality Python Packages

visqol-python

A pure Python implementation of Google's ViSQOL (Virtual Speech Quality Objective Listener) for objective audio/speech quality assessment.

nisqa

NISQA - Non-Intrusive Speech Quality and TTS Naturalness Assessment

the-a-files

Research toolkit for evaluating audio steganography and watermarking: payload recovery, signal quality, robustness, capacity and empirical detectability under a shared experimental protocol. Includes a Python API, declarative experiments and a browser-based research interface.

voicequal

Real-time audio quality assessment for voice apps. Is this recording clean enough to process?

utmos

A toolkit to calculate speech audio quality. Not affiliated with the original authors

mel-cepstral-distance

A Python library for computing the Mel-Cepstral Distance (Mel-Cepstral Distortion, MCD) between two inputs. This implementation is based on the method proposed by Robert F. Kubichek in "Mel-Cepstral Distance Measure for Objective Speech Quality Assessment".

noisekit

Generate degraded speech datasets for noise-robust ASR benchmarking
