Questions and Answers

Q1: May I request for a function enhancement for Speech Recognizer Extension? I want the function in the this link. This will be very helpful in a noise area, I can press a button and speak, and then I release the button to stop listening, like what it done in whatsapp speech. Can you add this in the extension for me?
A: The speech recognizer component and also this extension use the Recognizer Intent class and that class unfortunately does not offer that functionality. Someone will have to write a completely new extension.

For questions about App Inventor,
please ask in the App Inventor forum.Thank you.
