OpenSMILE

OpenSMILE (Speech & Music Interpretation by Large-scale Extraction) is an open-source software toolkit used to analyze audio recordings. It extracts detailed features from sound data—such as pitch, tone, rhythm, and energy—that can be used to understand emotions, speaker characteristics, or speech patterns. Commonly employed in research and applications like emotion detection, voice recognition, and health monitoring, OpenSMILE provides a systematic way to quantify aspects of audio signals. Its flexibility and robustness make it a valuable tool for transforming raw audio into meaningful, measurable data for various analytical purposes.
