Get the voices

From the source code

git clone git@github.com:bdoin/GCompris-voices.git


Alternatively, you can browse the voices online from the gnome git [1].

Create your voices directory

First copy the English voices as a template in a new directory with you locale name (e.g. my):

cd GCompris-voices
cp -r en my

Provide here voice translation in boards/voices/my for each English voice.

Recording / Encoding

It is best to choose somebody that speaks and articulate well your language (a teacher is a good candidate).

  • You can make the recording with audacity. It is mandatory to use mono wav 16bit/44100Hz to get the best quality/size ratio and because this works for any sound card.
  • Save as WAV file
  • Apply loudness transform with sox if necessary. You may use a script like this if the sound is too low:
mkdir modif
for i in *.wav; do
  sox $i -r 44100 -b 16 modif/$i norm
  • Remove noises if necessary:
mkdir as_wav
cd as_wav
oggdec ../*.ogg
mkdir filtered_wav
cd filtered_wav
for f in ../*.wav; do
  rm -f speech.noise-profile
  sox $f -n trim 0 0.2 noiseprof speech.noise-profile
  sox $f $(basename $f) noisered speech.noise-profile 0.3
  • In the directory where WAV files are run:
oggenc -q0 --downmix -a "(name of author)" -t "GCompris" -d "date of recording (YYYY/MM/DD)" -c "copyright=GPL V3+" *.wav

The ogginfo command should display the comment.

The last stage is to pass the tool normalize-ogg to make all the sound having a standardized volume level.

  • Copy OGG files in the corresponding directory


The English alphabet directory contains files named U0030.ogg. These are the voices for each single letter in your locale with a UTF-8 Unicode notation. For example, U+0030 is the character 0, and U+0069 is the character i. You can get the table for each subset.

Lang word list

The lang activity contains a set of about 1000 images originaly comming from the art4apps project and are released under CC-BY-SA. In order to make it available in your language, you must provide a voice recording of each words and an UTF-8 encoded file named content.txt that contains the translation of each word as spoken in the ogg file. The ogg files and the content.txt are in the directory boards/voices/<locale>/words. If your language has genders it is a good idea to enter them in the recording and the content.txt file.

You can view the list of words in the voices branch and the english content.txt. You can see on a single page the images and their english name.


Once done, the easiest way is to tar all this files and send them to the GCompris maintainer.

cd boards/voices
tar -cvzf voices_my.tgz my


Nothing has to be done, just run 'make install' at GCompris to level. The voices will be installed in the proper directory and GCompris will play them. Run GCompris in your locale and you should hear your voices.


At top level, run:

./tools/check_missing_voices.pl <locale>

With for example locale being fr for French.

Introduction Voice Set
