Praat review
Free, open-source desktop software for detailed speech analysis and annotation.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Praat is free, open-source desktop software for analyzing and synthesizing speech. Its tools are aimed at researchers, educators, and students working in phonetics and speech research, as well as people studying other sounds. It runs on Windows, macOS, and Linux. The combination of sound inspection, measurement, annotation, and manipulation gives speech-focused users a single environment for several kinds of analysis.
For analysis, Praat offers waveform and spectrogram displays alongside pitch, formant, and intensity analysis. Users can edit sounds, annotate recordings with text grids, and create or manipulate speech sounds. That breadth is useful when a project moves between inspecting a recording, measuring speech properties, and marking spoken material. Its feature set is centered on speech and phonetic work rather than general-purpose audio production, so buyers looking primarily for a broad editing environment should consider whether that focus fits their needs.
Praat is distributed without charge and is open source, making it an option for individual researchers and organizations that want desktop speech-analysis tools without a paid plan. Its desktop deployment means the workflow is based on software for Windows, macOS, or Linux rather than a browser. The published feature set does not include AI capabilities, so buyers looking for AI-assisted analysis should look elsewhere. Praat is a strong fit for speech researchers who need pitch and formant analysis together with annotation; it is less suited to users prioritizing browser access, AI features, or general audio editing.
