Similar to a fingerprint, every person also has a unique voice identity. Numerous software companies have developed technologies for the secure identification and authentication through this uniqueness of the voice. Excelsis is using the technologies of the world's leading providers such as Agnitio, IBM or Nuance as embedded components for the realisation of complex and highly secure identification and authentication solutions.

For further information, please read our product sheet.

Using voice prints as a password, these solutions provide higher security and comfort than the use of conventional passwords.

With voice biometrics, the authentication process can be conducted in several different ways. An overview of the most established methods:

Authentication in self service portals

The caller communicates with a voice portal, therefore the dialog is controlled by the voice application. First, the system finds out who the caller declares to be (for example by a customer number as "identifier"). Then, it requests the caller to repeat certain preset words (for example several four-digit numbers). With this data, the system can authenticate the caller and offer him the requested services.

Authentication parallel to the conversation with an agent

In some industries, especially in the financial sector, there is a policy to only personally speak to the customer. Every caller has to be connected to an agent immediately. In these cases, voice biometrics can be used to authenticate the caller parallel to the conversation. The agent can initiate a conference call with the authentication system which then takes over the dialog. The caller is authenticated in the same way as in a self service portal. It is also possible to conduct the authentication in the background. Herefore the agent's audio channel is separated from the caller's via CTI during the conference call, so that only the caller's audio channel is connected to the voice biometrics system. The agent then initiates the authentication by manually entering the "identifier". To authenticate the caller, the system uses the caller's voice data from the interaction with the agent.

Authentication in combination with callback

To secure transactions via a web or mobile application, the voice biometrics system can initiate a callback to a stored number. Here, no "identifier" has to be entered, and the customer can be identified by repeating several random words. The transaction which led to the call is approved only in case of a positive authentication.
