Praat is installed in Docker, but shows as unavailable to FAVE-extract

[Rolando Coto]

Hi, everyone!

I recently built a FAVE docker container in MacOS (High Sierra 10.13.4, using Docker Community Edition 18.03.1-ce-mac65 24312). FAVE-align worked perfectly, but FAVE-extract has a problem. When I tell it to extract, it tells me that 'praat' is not in my path.

root@5a1c128e7532:/opt/FAVE/FAVE-extract# ./bin/extractFormants.py /opt/audio/Rebecca1f.wav /opt/audio/Rebecca1f.TextGrid output

Processed options.

Read CMU phone set.

ERROR: Praat was specified as the speech analysis program, but the command 'praat' ('praatcon' for Windows) is not in your path

However, I installed praat (apt-get -y install praat), and it does appear to be available in the PATH variables. For example:

root@5a1c128e7532:/opt/FAVE/FAVE-extract# which praat 

/usr/bin/praat

root@5a1c128e7532:/opt/FAVE/FAVE-extract# echo $PATH

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/FAVE/FAVE-align:/opt/FAVE/FAVE-extract

root@5a1c128e7532:/opt/FAVE/FAVE-extract# praat

What am I missing in order to run FAVE-extract? Thank you so much!

Hi Rolando,

It might be a problem with case. extractFormants.py expects the name of the praat binary to be capitalized on MacOS and Linux (GitHub issue). If you don't mind doing so, one way to fix might be to create a symlink named Praat to the existing praat, as in that link. Otherwise, you could try making these two changes:

1) Update the config file to include:

--speechSoftware
praat

2) Uncapitalize the string "Praat" on line 2079 of extractFormants.py so that the line becomes:

PRAATNAME = "praat"

Maybe extractFormants.py could be changed to just check all of the expected names (praat, Praat, praat.exe, praatcon.exe, maybe others?) rather than guessing based on OS, since Praat 6.0 on Windows doesn't use praatcon anymore anyway.
