PhonBank is supported by grant RO1-HD051698 from NIH-NICHHD to Brian MacWhinney and Yvan Rose. The title is "A Shared Database for the Study of Phonological Development." This new database will rely on the PHON program, being designed and built by Yvan Rose and Greg Hedlund. PHON is designed to facilitate phonological and phonetic analysis of data transcribed in CHAT. We are working with a group of child phonologists to construct PhonBank. Currently available materials include:

Phon	The current version of the program and the online user manual.
Demo Corpus	14MB zip file with sample English transcripts and video
PhonTalk	PhonTalk Wiki
PhonBank Data	current PhonBank data in CHAT format and Phon format
PhonBank Data Manual	Descriptions of the corpora in PhonBank
PhonBank Media	Audio files for the PhonBank corpora in .wav and .mp3 format
Phon mailing list	To subscribe, send mail to phon-subscribe@googlegroups.com.
Workshop presentations	Presentations at the Newfoundland PhonBank workshop in July 2010.
Participants	A list of participants in the PhonBank project

Converting Phon to CHAT. To convert a Phon project to a folder of CHAT files, you first download the PhonTalk program. This program has two functions: converting XML to Phon, and converting Phon to XML. After starting the xml2phon program, you select your Phon project. Phon will choose the directory of your Phon project as the default output directory for your XML output files. Then click "Next" and Phon will start producing XML files. Next, you download the Chatter program. You click on Chatter to start it. Use the radio buttons to select the conversion from XML to CHAT. Then use the "Open" menu item to select the folder that has the XML files produced by xml2phon. Chatter will then create a folder of CHAT files.
