Day by day Optimism is growing that in the near future our society will
witness the Man-Machine Interface (MMI) using voice technology.
Computer manufacturers are building voice recognition sub-systems in their
new product lines. Although, speech technology based MMI technique is
widely used before, needs to gather and apply the deep knowledge of spoken
language and performance during the electronic machine-based interaction.
Biometric recognition refers to a system that is able to identify individuals
based on their own behavior and biological characteristics. Fingerprint
success in forensic science and law enforcement applications with growing
concerns relating to border control, banking access fraud, machine access
control and IT security, there has been great interest in the use of fingerprints
and other biological symptoms for the automatic recognition. It is not
surprising to see that the application of biometric systems is playing an
important role in all areas of our society. Biometric applications include
access to smartphone security, mobile payment, the international border,
national citizen register and reserve facilities. The use of MMI by speech
technology, which includes automated speech/speaker recognition and
natural language processing, has the significant impact on all existing
businesses based on personal computer applications. With the help of
powerful and affordable microprocessors and artificial intelligence
algorithms, the human being can talk to the machine to drive and control all
computer-based applications. Today's applications show a small preview of a
rich future for MMI based on voice technology, which will ultimately replace
the keyboard and mouse with the microphone for easy access and make the
machine more intelligent.
