Generate your own prompts

If you want your Wazo to speak in your language that is not supported by Wazo, and you don’t want to record the whole package of sounds in a studio, you may generate them yourself with some text-to-speech services.

The following procedure will generate prompts for pt_BR (portuguese from Brazil) based on the Google TTS service.


There are two sets of prompts: the Asterisk prompts and the Wazo prompts. This procedure only covers the Wazo prompts, but it may be adapted for Asterisk prompts.

  1. Create an account on Transifex and join the team of translation of Wazo.

  2. Translate the prompts in the wazo-prompt resource.

  3. Go to and download the file on your Wazo. You should have a file named like for_use_wazo_wazo-prompt_pt_BR.ini.

  4. On your Wazo, download the tool to automate the use of Google TTS:

    chmod +x
  5. Then run the following script to generate the sound files (set LANGUAGE and COUNTRY to your own language):

    mkdir -p wav/{digits,letters}
    cat for_use_wazo_wazo-prompt_${LANGUAGE}_${COUNTRY}.ini | while IFS='=' read file text ; do
      echo $file
      ./ -t "$text" -l ${LANGUAGE}-${COUNTRY} -s 1.4 -r 8000 -o wav/$file.wav
  6. Install the prompts on your system:

    mv wav /usr/share/asterisk/sounds/${LANGUAGE}_${COUNTRY}

Note that this last modification may be erased after running wazo-upgrade.

And that’s it, you can configure a user to use your new language and he will hear the prompts in your language. You may also want to use the wazo-confd HTTP API to mass-update your users.
