Abstract
This disclosure describes techniques for identifying users that are enrolled for use of a user-recognition system. To be identified using the user-recognition system, a user may first enroll in the system by stating an utterance at a first device having a first microphone. In response, the first microphone may generate first audio data. Later, when the user would like to be identified by the system, the user may state the utterance again, although this time to a second device having a second microphone. This second microphone may accordingly generate second audio data. Because the acoustic response of the first microphone may differ from the acoustic response of the second microphone, however, this disclosure describes techniques to apply a relative transfer function to one or both of the first or second audio data prior to comparing these data so as to increase the recognition accuracy of the system.
