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, analyze 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.
  • Data analysis: hypothesis testing, linear, logistic and Poisson regression
  • 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 GNU General Public License. The latest version can be downloaded from If you have questions, problems, or would like to report a bug, please contact us at
