Phonometrica is a free, open-source software platform for the annotation and analysis of speech corpora. It offers a user-friendly interface to manage, annotate and query language corpora. It is particularly well suited for dealing with time-aligned data. The main features it offers are:

  • Project management: organize files into projects.
  • Sound visualization and annotation: visualize and annotate speech sounds on multiple layers
  • Extensible metadata: annotate files with properties, which allow you to sort and organize your corpus.
  • Queries: build and save simple or complex queries; search strings or patterns across layers.
  • Scripting engine: Phonometrica can be configured and extended with an easy-to-use scripting language and JSON files.
  • Standard-based: Phonometrica files are encoded in XML and Unicode.
  • Interaction with Praat: Phonometrica can read and write TextGrid files and open files directly in Praat.

Phonometrica runs on all major platforms (Windows, macOS and GNU/Linux) and is freely available under the terms of the CECILL license (version 2.1). The latest version can be downloaded from If you encounter any problem or bug, please write to the authors.

Note: Phonometrica is currently under development: the documentation is still incomplete and some things might change before version 1.0 is released.
