Yes, you can use abbreviations in your script. In English and German, we also feature generic abbreviations.
For example, write “E.E.T.S.” or “eets” or “EETS” or “e. ets” but say “Early English Text Society”. However, it is important that the abbreviation contains all starting letters of the actual words in order. For other languages, abbreviations that are spoken as full words might decrease the matching quality.
