- Implementation of the Visqol v3.1 algorithm for speech quality evaluation in Rust
- Builds a command line executable which produces Visqol scores, with a more ergonomic command line interface compared to the C++ implementation.
- Also check out the library for using visqol within your Rust project!
Installation
- Assuming you have the
cargo package manager installed, type cargo install visqol to install the binary.
Usage
visqol --help or simply visqol will show you all the flags you can set when invoking the binary.
Note that the CLI tool has 2 subcommands:
- wideband: for speech signals, sample rate 16 kHz
- fullband: for music signals, sample rate 48 kHz
All command line flags pertaining only the individual modes will have to be specified after the subcommand.
Flags like --reference_file will have to be specified before the subcommand as they are mandatory regardless of which mode the algorithm runs in.
Example
visqol \ # command
--reference_file visqol-rs/test_data/clean_speech/CA01_01.wav \ # reference file
--degraded_file visqol-rs/test_data/clean_speech/degraded_signal.wav \ # degraded file
wideband \ # mode: wideband|fullband
--use_unscaled_speech_mos_mapping # flag for wideband mode only
