OpenSmile for Audio and Speech Analysis

Audio processing and acoustic feature extraction are critical components of modern speech recognition, emotion detection, and sound classification. This course guides you through the foundational concepts of OpenSmile, enabling you to extract and interpret acoustic feature sets from sound files for data science and research applications. What you will learn: Understand core audio signal terminology, wave characteristics, and digital speech representations. Configure OpenSmile tools and command-line parameters for audio feature extraction. Work with established standard feature sets including eGeMAPS and ComParE benchmark sets. Analyze vocal parameters relevant to emotion recognition and speech pattern detection. Prepare extracted audio feature matrices for integration into Python data processing pipelines. Practice executing feature extraction workflows through structured written exercises. You will begin by exploring fundamental acoustic terminology and signal representations before learning how OpenSmile processes raw audio inputs. From there, you will learn how to run extraction pipelines, select appropriate configuration files, and organize exported feature datasets. This course is created for beginners, data enthusiasts, and software developers interested in audio analysis with no required prior experience in digital signal processing.
