Phon 2 Public Release

It is with great pleasure that we are now introducing the second generation of Phon. Phon 2 brings together two of the most important areas of empirical investigation in phonology, as it integrates transcript-based analyses of phonological data with the facilities for acoustic analysis provided by Praat.

Brief description

Phon is a publicly-funded, open-source software program for the analysis of phonology and phonological development. Phon 2 improves on the functions offered in previous versions of the application. Among other features, we now have redesigned approaches to IPA Lookup (with support for both IPA dictionaries and transliteration) and Find & Replace (which now incorporates support for phonological and regular expressions), streamlined the layout of Record Data, and added new features, including a support system to assist the ever-important task of data anonymization.

Through our integration of many functions available via Praat, we have streamlined many tasks involved in the preparation of data for acoustic analysis. The user can now:

* Import existing TextGrids into Phon sessions
* Generate TextGrids from existing Phon records
* Visualize TextGrid and spectrogram data directly within Phon
* Send TextGrids to Praat for editing
* Run speech analysis functions directly from the Phon Query menu
* Export speech measurement data for further analysis in other applications

In this initial release, Phon 2 provides support for formant, pitch, and intensity analyses. Future versions will incorporate more analyses, for example of durational data (e.g. consonant/vowel length; VOT; …).


You can download this new version of Phon at
(Due to technical issues specific to the Linux platform, we will need a few additional weeks in order to release Phon 2 for Linux.)
Keeping with the communal nature of this project, we invite you to submit your requests as well. We also welcome questions and feedback on every aspect of Phon, as we look forward to improving this initial release in close collaboration with our users.

Special thanks

We would like to express very special thanks to Paul Boersma. Without his generous help and support, it would have been much more difficult to implement the interactions between Phon and Praat which underly many of the new functions in Phon 2. We are also thankful to our close collaborators at Carnegie Mellon University, Brian MacWhinney, Leonid Spektor, and Franklin Chen, for their continuous support as we continue to improve and add new facilities for the CHILDES/PhonBank database system. This collaborative project is funded by a grant from the National Institutes of Health.

Kindest regards,

Yvan Rose & Gregory Hedlund
