Can you elaborate and clarify what you are talking about?Is there an automatic translation site or application? can you help me?
Are you asking for an application that automatically translates SPOKEN/SOUND language....or an application that automatically translates WRITTEN translations into a different language?
If you want an application that will automatically translate a subtitle file (.srt for example) to a different language (Chinese to English for example) then Subtitle Editor is a good option. ( I am pretty sure it's been mentioned several times in this thread, actually).
