feasability

Am I able to use an Arduino to capture sound and turn that sound into vibrations on specific coin cell motors (9)? Can I use coding to turn that sound produced say in the Spanish language to English though code where I used the Arduino to tell me what the words are then processed it through google translate to get it in English then send vibrations to the vest??

No. Your final solution might use an Arduino in there somewhere but most of the work will require something like a Rasberry Pi.
