This describes the web services that support verification of a user's identity by analysing their voice.
A user must first register in a user group, by supplying initial audio data of their voice. This constructs a voice model for that user which should be updated with more audio voice data to refine the model. At regular intervals, the model can be further updated to cater for natural aging, changes in environment etc.
Registering and updating a user's voice model is secured by access keys which can be created for each user group.
You can perform voice biometric registration and verification via the Users API, manage user groups with the User Groups API and manage user group access keys with the User Group Keys API:
