-or and -er say ER: doctor, actor, color
-or et -er se disent « er » faible : doctor, actor, color

What French speakers do
You use the French -eur ending, full and stressed: doc-TEUR, ac-TEUR, é-REUR.
The American rule
-or / -er / -our = a weak ER (the American R, no real vowel before it). The stress goes earlier in the word: DAHK-ter, AK-ter.
French -eur words (docteur, acteur, erreur, couleur) have English twins ending in -or. In American English that ending is just a weak -er — an R-colored uh, never stressed:
- doctor = DAHK-ter
- actor = AK-ter
- color = KUL-er
Two fixes at once: move the stress to the front, and replace the French eu + throat R with the American R alone.
