Stay organized with collections
Save and categorize content based on your preferences.
Supporting voice actions helps users find and play media by talking to Google
Assistant, so they can keep their eyes on the road.
Google and car makers control how users invoke Google Assistant, typically via
hotword (“Hey, Google” or “Hey, G”), steering wheel button, or onscreen
affordance. Once invoked, Google Assistant can recognize requests to play
app-supported categories of media, as well as requests to pause media play or
advance to the next track.
To optimize the voice experience for your users, you need to:
Decide which media categories to support. Possible categories for voice
actions include genre, artist, album, playlist, and title. Choose those that
make sense for your app.
Anticipate non-specific requests. Decide how you want your app to respond to
requests that don’t ask for specific media content, such as “Play some
music.”
