Speech Intelligibility Index

A Python implementation of American National Standard ANSI S3.5-1997 "Methods for Calculation of the Speech Intelligibility Index" This code is translated from Hannes Muesch's Matlab implementation.

This package includes both Python/Numpy and Python/JAX implementations.

There is a Google Colab that demonstrates how to use this code and shows typical results. This colab is a good place to start: https://colab.research.google.com/drive/1bAnDpUUx5-BYkL3l3ukNVVnsLzEhy-ds.

For more information about the speech intelligibility index (SII) please see the Acoustical Society of America (ASA) working group's web site at https://sii.to/index.html.

To use these scripts successfully, you might want to be familiar with the concepts and definitions of the Speech Intelligibility Index (SII). You can obtain a copy of the standard at the ANSI webstore https://webstore.ansi.org/standards/asa/ansiasas31997r2017

You can reach out to the members of the Acoustical Society of America (ASA) Working Group S3-79, which is in charge of reviewing that standard, at https://sii.to/index.html.
