• Praat Formants Python Reading formants from audio files into Python by wrapping calls to [[http://www.fon.hum.uva.nl/praat/][Praat]]. To reduce overhead, calls to Praat are memoized. This can be disabled by setting ~memoize_call=False~ in the function parameters.

** Usage Extract formants at time point 0.5s from wavfile: : import praat_formants_python as pfp : pfp.formants_at_time('/path/to/wavfile/', 0.5)

Extract formants at time interval [0.5, 0.7] from wavfile: : import praat_formants_python as pfp : pfp.formants_at_interval('/path/to/wavfile/', 0.5, 0.7)

Maximum formant, window length and preemphasis can be passed in as keyword arguments. By default, these are set as ~maxformant=5500~, ~winlen=0.025~, ~preemph=50~ : import praat_formants_python as pfp : pfp.formants_at_interval('/path/to/wavfile/', 0.5, 0.7, : maxformant=5000, winlen=0.50, preemph=99)

** Installation This package requires [[http://www.numpy.org][numpy]]. See installation instructions there.

Run ~setup.py~: : python setup.py install

To be able to find Praat, the ~praat~ executable should be in your ~PATH~. For OSX: the Praat program installs to ~/Applications/Audio/Praat.app/Contents/MacOS/Praat~, which is not in the ~PATH~ by default. Easiest way to solve that is to put a symlink in /usr/bin to there, i.e. open a Terminal and do : $ sudo ln -s /Applications/Audio/Praat.app/Contents/MacOS/Praat /usr/bin/praat For Linux: Praat installs to ~/usr/bin~ by default, so you don't have to do anything.
