> MTPE (Machine translation, post-editing). This works just like it sounds. The initial translation is done with machine translation, then human translators review and edit the resulting translation to try to correct any mistakes.

And the consensus among professional translators is that MTPE only saves time if you're willing to accept a half-assed result. For them to edit MT up to the standard of manual translation takes just as much expertise and effort as translating it manually in the first place.
