Speech recognition is the process by which acomputer (or other type of machine) identifiesspoken words. Basically, it means talking to a
computer & having it correctly understand whatyou are saying. Speech recognition is an alternative to
traditional methods of interacting with acomputer,such as textual input through akeyboard. An effective system can replace, orreduce the reliability on, standard keyboard andmouse input.

Two level security lock. To embed this technology in the latest versions
of cars. To implement its security aspect remotely, may
be telephonically. Banks and MNCs can use this type of
applications as security as the authenticity ofspeaker will be governed marvelously.
Telebanking can use actual speakers voiceinstead of his phone number as the the securitymeasure.
Wide range of libriary so that people of different
dialect may not find it difficult to use.

Speech recognition will revolutionize the waypeople interacted with theSmart devices and
will ultimately differentiate the upcommingtechnologies. Within 5 years speech recognition technology
will become so pervasive in our lives thatservice environments lacking this technologywill be considered inferior.
