Access control

Together with the development of biometric technology, voice recognition technique has also been applied to a variety of fields necessary for security.

Voice recognition is one of the biometric recognition fields, and it helps to authenticate the speakers on the basis of their own voices.

Voice recognition can mainly be divided into speaker identification and speaker verification.

Speaker identification is to authenticate the speaker among the registered ones (1:N matching); speaker verification is to determine whether the input speech belongs to the person registered in the database (1:1 matching).

Like the other biometric identification technologies, the speech recognition technique is based on the unique voices of persons for individual identification, and worthy of development application.

The voice recognition technique is widely used for telephone or internet-based service business, computer security management, electronic household appliances, toy management, access control and lock control. It can also been used in combination with other biometric technologies.
