Phonetic Analyzer

Acoustic phonetics is the study of the physical properties of speech sounds such as frequency, amplitude, and duration. Researchers and students typically rely on tools like Praat to analyze these properties.

As a typical native application, Praat requires installation and can only run on desktop operating systems. To make Praat's functionality more accessible and fully platform-independent, I started building the online version of the program.

This web-based phonetic analyzer uses parts of Praat's codebase compiled to WebAssembly (WASM) to perform phonetic analysis locally in your browser. With this more accessible and convenient way to analyze the physical properties of speech sounds, you can explore and study phonetic features on any device including smartphones and tablets.

Using this tool, you can record or upload audio files, visualize spectrograms, measure pitch and intensity, and calculate formant frequencies.
