I was wondering if it was possible to integrate the Google Assistant SDK into my own Android app?
I would like to use voice transcript from the user in order to perform certain actions in the app.
According to the Google Assistant SDK guide page:
The Google Assistant gRPC API gives you full control over the integration with the Assistant by providing a streaming endpoint. Stream a user audio query to this endpoint to receive a Google Assistant audio response.
That guide page will help you integrate and use google assistant in your app - your users say something and receive an audio response from Google Assistant.
And if you want actions, you will need to use api.ai - which allows you to build apps for the Google Assistant.
