First of all you need to have the language file available; to find it, just go to your personal area and download it together with the firmware of the desired product.
The file, which will have a name in STR*24.S24 format, must be extracted from the .zip folder and opened with a text editor such as notepad or notepad++.
The lines present in order:
- the card version
- the number of languages and the languages present
- the lines of text that will be read for each language
If you want to change the voice in an already existing language, simply change the desired voice and then save the file.
If you want to add a new language, you will need to change the number of languages indicator, making it go from 2 to 3 for example, add the name of the new language in the language list and then add the translated text on each line.
The modified file must then be placed on the USB stick and imported from the card with the appropriate function present in the USB menu.
