Download praat.tmLanguage and the six snippet files (you can just clone the whole repository if you want). Open Sublime Text and go to Preferences Browse Packages. There, create a folder called 'Praat' and save all the downloaded files inside that new folder. Download: Praat is available for Windows, Mac, and Linux, among others. The source code is also available. Documentation: A copy of the official Praat manual comes with an installation of the program and is also available online. Similar software. PhotoFiltre Studio X 10.14.0. A complete image retouching program. Get the latest software for Windows, Mac and Linux. I am currently working on a 64-bit edition of Praat for the Mac. Once that works it becomes possible to spin off smaller apps for the iPad and iPhone, because programming those is similar to programming in 64-bit on the Mac.

Entropic Signal Processing System (ESPS)

  • History: Originally a commercial product of Entropic Research Laboratory, Inc. (commonly abbreviated 'Entropic'), the following bundle of software was extremely popular in phonetics labs around the world in the 1990s:
    1. Entropic Signal Processing System (ESPS): a collection of over 200 UNIX commands and programming libraries (written in C) for speech signal processing
    2. waves+: a set of functions for interactive data visualization and manipulation of data processed by ESPS. The program that forms the core of the waves+ package is known as 'xwaves'.
    3. EnSig: A higher-level graphical user interface for setting waves+ preferences and behavior with interactive prompts

    After Entropic was acquired by Microsoft in 1999, the rights to the final legacy version of the ESPS source code (i.e. #1 above, but not #2 or #3) was donated to the Center for Speech Technology (Centrum för TalTeknologi, CTT) in the Department of Speech, Music, and Hearing (Tal musik och hörsel, TMH) at the Royal Institute of Technology (Kungliga Tekniska högskolan, KTH) in Stockholm, Sweden. This code was incorporated into the Snack Sound Toolkit. (See above.)

  • Download: The ESPS source code can be obtained in any the following ways:
    • as a zip file directly from the Center for Speech Technology
    • from a mirror on Github
