Akustyk for Praat

Akustyk is a comprehensive vowel analysis software package. It installs as an add-on to the popular software, Praat (http://praat.org), developed at the University of Amsterdam. It has been designed to facilitate accurate and sophisticated acoustic analysis of large data sets. Akustyk's functionality ranges from preparing audio files for analysis to producing high quality plots and graphs. Akustyk is of particular value to researchers working in the field of sociophonetics, though it may be successfully used in other fields as well. Akustyk has also been implemented in student labs, where it is used as a graduate student research and teaching tool.

Akustyk is free and open-source. I receive no funding for the development and maintenance of Akustyk. If you find Akustyk useful and would like to support its further development, please make a secure donation via PayPal by clicking the button below (any $US amount you'd like).
