I want to automatically align my audio to my video footage as I have to sync my videos to different languages. I have cut my comps to different parts so its easy to sync with the audio but I work with Voice Overs in 7 different languages I want someone to tell me a idea so that whenever I put my audio files in the main comp the pre-comps are automatically stretched or adjusted with respect to the audio files assigned to each comp.
Automatically? I don't know of a way (perhaps a script might be out there somewhere). But you can apply time remapping to the precomps and adjust them yourself pretty quickly.
You're using the wrong tool for the job. Use a video editing application.
Personally, unless I completely misunderstand the what you are doing, I would never do that kind of thing in After Effects. You can make multiple copies of a sequence and change the language and timing in Premiere Pro in seconds. AE is not an editing app. If you are not doing visual effects, compositing or motion graphics you should be using Premiere Pro. It will save you boatloads of time.
