Getting Started


Phon is a software program that supports the building of textual and phonological data corpora. While it was originally created to support the study of child language development, Phon can be used across virtually all types of corpus studies (e.g. textual, phonological, acoustic, clinical) based on child or adult language data. Among other features, Phon offers specialized support for research on phonological units (e.g. phones, phonological features, stress, tones) and includes some specialized functions for clinical speech analysis. Phon also incorporates Praat functions for acoustic data analysis.

Funding: Current development of Phon and PhonBank is supported by the National Institutes of Health. Earlier development of Phon was funded by grants from National Science Foundation, Canada Fund for Innovation, Social Sciences and Humanities Research Council of Canada, Petro-Canada Fund for Young Innovators, and the Office of the Vice-President (Research) and the Faculty of Arts at Memorial University of Newfoundland.

Dictionaries: Built-in dictionaries of pronounced forms were obtained from generous organizations and people, to whom we are indebted:

Special thanks: While it is impossible to name everyone who ended up being involved in one way or another in this project, we owe special thanks to a wonderful group of early adopters and beta testers, students and researchers alike, without whom it would have been much more difficult to produce the current software program. We are also grateful to Paul Boersma for this tremendous collaboration toward the interactions between Praat and related functions within Phon 2.
