Axel, as a qualified pedant, I disagree with your pronunciation guides for Traceur and Babel.
The 'a' in Traceur is a short one (at least in French) – like the English 'attend' (or Axel?), as in the link you provide; 'truh' seems a long way from this. I would suggest 'trassir' would be closer.
A treacherous business, pronunciation!
