Yes exactly, the crash words found so far all concern eloquence exclusively. Eloquence in Jaws, NVDA, your good old nokia phone, your braille notetaker, or whatever else using eloquence.
We have never received any crash word directed to any other synthesizer til now.
What makes me angry in this topic is that these eloquence crash words exist since 10 years, and that even freedom scientific can't do anything against them except adding them to the default dictionary.
Adding words to the dictionary has limits unfortunately; we have discovered a few patterns that can cause crashes, and there are an infinite number of possibilities.
I wont reveal the trick here, but any word having a well defined prefix and suffix with anything you want in between will make eloquence to crash. If you know these prefixes and suffixes, you can invent what you want in the middle of the word and it will crash.
A dictionary based on regular expressions is needed to protect ourselves against them altogether.
