Voice Match is quite a useful feature offered by the Google Assistant, specially for household with multiple users. In an APK teardown of the Google Search app v4.2 for Android TV, deeper integration of the Google assistant was spotted, including the Voice Match feature.
With Voice Match, the Google Assistant will maintain separate profiles for each user who share the same Assistant devices like smart displays and speakers in a household. When the Assistant is given a command, it can use Voice Match to respond to the user with personalized results and help.
At the moment, triggering the voice assistant on Android TV will only personalize the results according to the user that is signed in. With Voice Match, multiple users can use the Assistant, which will provide results specifically for them. This can be useful in scenarios like signing into different Netflix accounts or signing into different Stadia accounts in the future.
Recently, a leak containing renders of Google’s upcoming Android TV dongle surfaced. It was codenamed “Sabrina” and was rumored to run a full-blown version of Android TV instead of just being a shell for Chromecast. It is possible that Google could be preparing to launch the Voice Match feature along with the new dongle in the near future.
