If you’re using active Voice Biometrics, you need to say a passphrase to enable the system: first to establish a baseline, and afterward to check your unique voiceprint.
Talkdesk Identity™ includes a series of pre-configured pass-phrases. With some of these passphrases, Identity performs:
1. Utterance checks, i.e., detecting whether you are saying the right phrase. This is used to guarantee that the spoken passphrase matches the one requested.
2. Second speaker checks, i.e., detects if two users are creating a voiceprint (aka enrolling) as if they were one user only. This ensures there is a 1:1 ratio between a voiceprint and a single user.

Passphrases not supporting Utterance and Second Speaker Verification

| English | My password is my voice. | No | No |
| Spanish | Mi contraseña es mi voz. | No | No |
Note: The passphrase “My password is my voice” can be used with or without utterance and second speaker support. To choose without the support of both in the Passphrase selection box, you need to select the passphrase that has “(no utterance)”, as in the image below.
An admin can also configure a specific custom passphrase, more suitable for their relationship with the customers. In this case, neither utterance nor second-speaker verification is supported.
