UT-Sarulab MOS prediction system using SSL models

Unofficial UTMOS Python Package

This is an unofficial Python package for UTMOS (UTokyo-SaruLab MOS Prediction System). This repository is based on the original code. The paper is available here.

What is UTMOS?

UTMOS is designed for calculating the mean opinion score (MOS) for a given voice sample. It can be used to calculate audio quality for datasets.

Note

The score is on a scale of 1 to 5. If you'd like a score on 1 to 100, just multiply the score by 20 (score * 20).

Example: new_score = round(score * 100, 2)

Support

This implementation supports CPU, CUDA, and MPS, as well as ROCm if PyTorch is configured properly. This implementation will automatically use the GPU if available.

Installation

pip install utmos

Usage

CLI (Command Line Interface)

utmos audio.wav

Python API

import utmos
model = utmos.Score() # The model will be automatically downloaded and will automatically utilize the GPU if available.
model.calculate_wav_file('audio_file.wav') # -> Float
# or model.calculate_wav(wav, sample_rate)
