Praat, the famous GUI program for doing speech analysis and synthesis is part of Debian. However, the package is outdated in Debian stable (a.k.a. "jessie"). In this website, you will find an the APT repository with the Debian packages for Praat that work in both the stable and testing (a.k.a "stretch") distributions, for recent upstream versions and for the amd64 and i386 architectures.
For installing them, run the following command (as root):
echo "deb http://praat.cefala.org/ jessie main" > /etc/apt/sources.list.d/praat.list
echo "deb http://praat.cefala.org/ stretch main" > /etc/apt/sources.list.d/praat.list
whether you are using the "jessie" or the "stretch" distribution, respectively.
This repository is signed. You should add the public GPG key to your APT configuration, as follows:
wget -O - http://praat.cefala.org/praat.gpg.key | apt-key add -
Once this is done, run the following commands:
aptitude update aptitude install praat/jessie
aptitude update aptitude install praat/stretch
(You might also use "apt-get" instead of "aptitude" in the commands above.)
