Eric Payne has created an Apple Siri – like interface in App Inventor.
You can download his App Inventor source code here from Google Drive. Note that Google Drive displays the content of the .aia file (it is just a .zip file). Click on the “download arrow” icon at top center to download the .aia file to your computer, and then import the .aia file into your App Inventor account.
