Abstract: Systems and processes for speech recognition for multiple users are provided. For example, in response to receiving speech input from a user, a combined speech profile is obtained from a plurality of speech profiles. The speech input is interpreted based on the combined speech profile to obtain a plurality of speech recognition results. The plurality of speech recognition results includes a first speech recognition result corresponding to a first speech profile of the plurality of speech profiles, wherein the first speech profile corresponds to a first user, and a second speech recognition result corresponding to a second speech profile of the plurality of speech profiles, wherein the second speech profile corresponds to a second user different from the first user. A respective speech recognition result based on an identified voice profile is then selected from the plurality of speech recognition results.
