Once invoked, Google Assistant can recognize requests to play\napp-supported categories of media, as well as requests to pause media play or\nadvance to the next track.\n\nTo optimize the voice experience for your users, you need to:\n\n- 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.\n- 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.\"\n\n| **Note:** For details about how to build support for voice actions into your app, consult [Support voice actions](https://developer.android.com/training/cars/media#support_voice) and [Google Assistant and media apps](https://developer.android.com/media/implement/assistant/).\n\nVoice plate example\n-------------------\n\nVoice action requirements\n-------------------------\n\nIn the table below, SHOULD requirements are recommended but not required.\n\n| Requirement level | Requirements |\n|-------------------|-------------------------------------------------------------------------------------------------------------|\n| **SHOULD** | App developers should: - Support voice actions for all media categories that are appropriate for their apps |\n\nRationale\n---------\n\n- **Minimize visual distraction**: Users controlling media via voice can keep their eyes on the road."]]
