Passphrase

You can select either a "Predefined" passphrase from the list or choose "Custom".

The list of predefined passphrases contains several phrases that will validate against utterance and second speaker detection and others that won't and that are identified by “(no utterance)”. For more information on utterance and speaker verification, please refer to the documentation.

If you choose "Custom", then you can set up the passphrase that the caller will hear while enrolling and later authenticating directly in the messages.

Beep

Choose whether the caller should wait for a beep signal before saying the passphrase.

By default, the beep signal is disabled.

It is recommended that the instructions indicate that a beep signal will be heard and that only after the caller should say the passphrase.

Keypress

Select if the caller needs to press a key after saying the passphrase, or if you prefer the system to detect the silence and proceed.

By default, keypress is enabled.

When enabled, it is recommended that the instructions indicate that it is necessary to press any key after saying the passphrase to complete the authentication.

Voice enrollment message

Configure the audio message the caller will hear during enrollment and make sure that the instructions are clear.

You can choose one of the following message types: Text to speech, Audio file upload, or Other sources.

Text to speech

This first option allows you to type a message that will be converted to audio and played to the caller.

To ensure a successful enrollment, the passphrase chosen previously should be stated during the audio instructions. To use a passphrase selected from the Predefined list, use the variable {{passphrase}} when typing the message for the caller.

Caller unique identifier

The caller's unique identifier is a personal and non-transferable number of which the caller is the sole holder and that will be used to perform a secure authentication every time the user calls in.

The default value is the caller’s phone number, but you can add an Input IVR or another component to add a different variable that will be used as the unique identifier.

Examples of a Caller's unique identifier that can be used include:

Bank account number.
Credit card number.
Social Security Number.
ID Card number.
Personal Phone Number.
Any other set of digits that uniquely identifies the user calling in.
