are used to authenticate a speaker's identity using their voice. It is also known as voice recognition, speaker recognition, voiceprinting, and voice Authentication
. Voice Biometrics
identifies specific speakers rather than the words they say. Each person's voice has distinguishing characteristics determined by our anatomy and behavioral speech patterns. The shape and size of each person's mouths and throats, as well as their language, pitch and speaking patterns - fast-talking versus slow-talking - all shape their unique voices. Voice Biometrics
maps a speaker’s unique characteristics and then uses the audio map for later identification. A user provides one or more audio samples, which the system analyzes to create a unique voiceprint for the speaker. Whenever the user speaks, the software compares the speaker’s voiceprint to the voiceprint on file.
