The growth of video conferencing has propagated the use of inexpensive video cameras. More and more cameras are found in the workplace and may eventually be found in every home or on every personal computer. Face recognition software is fitting for industries such as retail, financial and security markets, healthcare and e-commerce in order to conduct business efficiently and securely. Voice biometrics works by digitizing a profile of a person s speech to produce a stored model voiceprint or template. The position and movement of the glottal tissues, lips, jaw, and tongue correspond with speech movements in the vocal tract.
Biometric technology reduces each spoken word into segments.
Each segment has three or four dominant tones that can be captured in digital form and plotted on a table or spectrum. This table of tones yields the speaker s unique voiceprint. When a user attempt to gain access to protected data, a pass phrase is compared to the previously stored voiceprint in the database. Each user has unique vocal features. These unique features are the characteristics that are compared with the enrolled pass phrase and are utilized to determine successful authentication.
