Praat is a program for speech analysis and synthesis written by Paul Boersma and David Weenink at the Department of Phonetics of the University of Amsterdam. The Praat website is here. The program is constantly being improved and new builds are published frequently.
There is a Praat Users discussion group where queries and allied topics are discussed, with responses from colleagues or from the authors themselves. Topics range from elementary “how do I” queries to advanced issues in scriptwriting. There’s something there for everybody. You can sign up to become a member on the Praat website).
Praat is available for download from the Praat website (instructions here). Update frequently in order to get the latest functions and corrections.
Paul Boersma and David Weeninck produce separate editions of Praat for various operating systems, e.g. MS Windows, MacOS, Solaris, Linux etc. All editions function and look alike, with the exception of odd details. The most obvious differences are mainly how they look on the computer screen, and the individual sound systems they happen to use (electronics and progams). The correct edition for your computer system can be downloaded from the Praat website. Note that some OS versions are no longer fully supported and some suitable older version of Praat might be recommended (see the Praat website for details). Similarly, newer versions are no longer provided for Solaris and Linux, however the latest source code is available for compilation.
Version 5 was introduced in December 2007, version 5.4. in October 2014, and the last build was 5.4.22. Version 6 was introduced on 28 October 2015, and the current build (March 2019) is 6.0.50.
If there are particular difficulties with any operating systems, they are usually listed on the Praat home page or download page. Other system difficulties are often mentioned as they arise on the Praat Users discussion group.
