Now-a-days databases have become an integral part of human life. Every human maintains his/her data in some form, which he/she understands easily. Multiple heterogeneous databases are used whose operations will be handled by using speaker vocals, i.e. speaker will issue a vocal command and the databases will act/respond so. The main aim is to make use of voice (i.e.) vocal tone to operate multiple databases, thereby providing complete hands-free human and database interaction. Multiple database concept acts as a lifeline by providing protection against database crashes, data loss, etc...(Say if one database containing all the essential data crashes (or) corrupts the other database comes into the rescue and the data's can be retrieved from it).
