15. A computer-readable storage device storing instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising: determining candidate user profiles that are associated with a shared digital assistant device; determining that a mobile computing device that is associated with a particular candidate user profile, from among the candidate user profiles that are associated with the shared digital assistant device, is indicated as being proximate to the shared digital assistant device; identifying, from the candidate user profiles, candidate pronunciation attributes associated with the particular candidate user profile that is associated with the mobile computing device that is indicated as being proximate to the shared digital assistant device; receiving, at the shared digital assistant device, a spoken utterance; determining a received pronunciation attribute based on received audio data corresponding to the spoken utterance; comparing the received pronunciation attribute to at least one of the candidate pronunciation attributes that are associated with the particular candidate user profile that is associated with the mobile computing device that is indicated as being proximate to the shared digital assistant device; selecting a particular pronunciation attribute from the candidate pronunciation attributes that that are associated with the particular candidate user profile that is associated with the mobile computing device that is indicated as being proximate to the shared digital assistant device based on a result of the comparison of the received pronunciation attribute to at least one of the candidate pronunciation attributes; and providing the particular pronunciation attribute, selected from the candidate pronunciation attributes, for outputting audio associated with the spoken utterance.

The computer-readable storage device of claim 15 , wherein determining candidate user profiles that are associated with a shared digital assistant device comprises: determining a relationship between each of a plurality of user profiles and the shared digital assistant device; determining, for each user profile, whether the relationship is indicative of an association between the user profile and the shared digital assistant device; and identifying, for each user profile having a relationship indicative of an association with the shared digital assistant device, the user profile as being one of the candidate user profiles associated with the shared digital assistant device.
