Speaker identification vs verification

VoiSentry voice biometrics allows users to clearly understand who is calling or speaking on a voice channel using speaker identification or speaker verification.

While speaker verification allows for a one-to-one comparison to a single reference file (voiceprint) generating a simple yes/no result, identification compares the speaker’s voice to a database of multiple voiceprints. This allows the system to return a unique value combined with a degree of confidence.

VoiSentry can be implemented quickly and cost-effectively into almost any business or customer interaction solution. Whether on-premises or in the cloud, VoiSentry enables organisations to replace costly, time-consuming and frustrating identification processes by allowing customers to interact using their voice.
