It takes two audio signals\u2014one clean and one degraded by noise, processing, or vocoding\u2014and returns a score correlating with perceived intelligibility. The package wraps numpy and scipy to perform the time-frequency analysis underlying the STOI algorithm.\n\nThe measure is intrusive (requires both signals) and serves as an alternative to speech intelligibility index (SII) or speech transmission index (STI), particularly useful when evaluating nonlinear processing like noise reduction or binary masking. It was ported from Cees Taal's original Matlab implementation and includes both classical and extended variants.","worth_installing":"Yes, if you need an intrusive intelligibility metric for speech signals and can accept dormant maintenance. The package is stable, has low install friction, carries no security vulnerabilities, and is MIT-licensed. However, verify compatibility with your Python version and confirm the codebase meets your performance needs, since the last release was 959 days ago."},"id":"pystoi","links":{"html":"https://skillfed.io/packages/pystoi","md":"https://skillfed.io/packages/pystoi.md","pypi":"https://pypi.org/project/pystoi/"},"maintenance":{"status":"dormant"},"meta":{"latest_release":"2023-12-29","license_spdx":null,"license_treatment":"permissive","name":"pystoi","python_support":"unspecified","summary":"Computes Short Term Objective Intelligibility measure"},"popularity":{"monthly_downloads":921980,"position":4716,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.4.1"}
