I am not sure that Linux has this kind of software developed yet.
The software is typically used by people who are visually impaired.
The list is:
1.Jaws (Screen reader)
2. MAgic screen magnifier (maginifes the desktop and has a screen reader component.
3. Kurweil 1000
4. Kurweil 3000
Unfortunately these are very expensive programs. The most appropriate program for your circumstance is Kurweil 3000. It is like the most advanced word processor ever created. It speakes English, French, German, Italian and Spanish.
It will load the correct fonts and character sets for those languages and it has a built in dictionary and thesurus which can be used entirely in the native language or as a english to spanish or French to German, etc. translation dictionary.
It costs about $5000 USD
If you are lucky your local library may have copy that you could use.
There are also some schools that offer voice training for learning english diction.
