**TLDR:** A more controlled speaker verification approach in which the speaker says a fixed phrase or passphrase.

<p>Text-dependent speaker verification uses both speaker identity and the specific phrase spoken. This can produce more secure and stable results, especially in spoken passphrase systems. However, it is more restrictive than free-speech verification from a user-experience perspective. It is a classical but effective security approach combining voice biometrics with content constraints.</p>
