“Hassio, turn lights in kitchen on” - Using HA Voice Assistant on Android like Amazon Alexa, Google Assistant or Bixby?

Hey folks,
controlling the Homeassistant instance by using the Google Assistant (&Google Home) voice commands works quite a while.

Nevertheless, not all sensors and switches are accessible in Google Home, the Google cloud saves private information and the voice commands are less customizable (like changing the “Hey Google …” command). A good reason to discuss if there is a possibility to use a Homeassistant Voice Command in Android app.

As far I know Siri already supports the HA Voice command but in Android just Google Assistant is possible.

Is there a way to implement the Home Assistant Voice Input as constant Voice Assistant in the Android phones? (e.g. Call via voice command “Hassio, turn lights in kitchen on”)
