Techniques for training a speaker recognition model used for interacting with a digital assistant are provided. In some examples, user authentication information is obtained at a first time. At a second time, a user utterance representing a user request is received. A voice print is generated from the user utterance. A determination is made as to whether a plurality of conditions are satisfied. The plurality of conditions includes a first condition that the user authentication information corresponds to one or more authentication credentials assigned to a registered user of an electronic device. The plurality of conditions further includes a second condition that the first time and the second time are not separated by more than a predefined time period. In accordance with a determination that the plurality of conditions are satisfied, a speaker profile assigned to the registered user is updated based on the voice print.
