* Maximum audio input length per request is **10 seconds**
* Minimum number of enrollments for creating a voiceprint is **3**
* Maximum number of enrollments for creating a voiceprint is **50**
* Minimum audio Signal-to-noise ratio (SNR) is **10dB**

Constraints:
* First enrollment must match an existing passphrase.
