This interaction mode allows users to send single very quickly, reducing the number of steps required and allowing an interaction that does not force users to look at the screen or interact with it, in a faster and easier way than Siri or Google Assistant, IMHO.

Current interaction model, 5 steps:

  1. Find the app
  2. Launch the app
  3. Select the recipient
  4. Press the Register button, speak and release the button
  5. Close/Switch the App

Proposed interaction model, 2 steps:

  1. Press the volume buttons, speak and release the buttons
  2. Pronounce/Select the recipient

In the use case where a user is already interacting with his phone, this interaction model could be very handy cause he doesn’t have to switch app, he just has to click on the volume controls to record and send the message. The app closes automatically after the message, without leaving the user the task of returning to the previous app.

I don’t like voice messages so much but almost the same concept could be used to send text messages adding a speech to text feature to convert the voice message before sending it.

Leave a comment if you have any feedback I would love to hear it!

*At the moment the Android OS allows apps to customize/remap the behavior of the physical keys (via accessibility service), functionality denied to iOs devices for as much as I know.
