Claim 0:
1. A computer-implemented method comprising:
receiving, from a device, input audio data corresponding to an utterance;
receiving a device identifier corresponding to the device;
determining, using the device identifier, a group identifier corresponding to the device;
selecting, based on the group identifier, a first personal identifier associated with a user associated with the group identifier;
determining a second personal identifier representing a guest user is temporarily associated with the group identifier;
identifying first automatic speech recognition (ASR) model data corresponding to the group identifier;
identifying second ASR model data corresponding to the first personal identifier;
identifying third ASR model data corresponding to the second personal identifier;
performing, based on the first ASR model data, the second ASR model data, and the third ASR model data, ASR on the input audio data to generate text data;
performing natural language understanding (NLU) processing on the text data to generate NLU data; and
sending the NLU data to a skill configured to execute the NLU data.
