Hi, can you send me your aia so I can see whats wrong? You should be a bit more descriptive of what you are trying to do. And just saying, out of these images, the blocks are the most important. You should always have images of the blocks.
Are you trying to do speech recognition in the emulator?
it seems to be you are getting a no such class error while using an extension together with the companion app...
How to avoid runtime errors with the companion app
- After importing an extension, please restart the companion app.
- If you like to use an extension on a different screen, in Screen1 additionally drag the extension into the working area.
While starting the companion app, all necessary assets and also the imported extensions of your project will be copied to your device. So in case the no such class error shows up, the extension code to run the extension is not available on your device. Without that code the companion app is not able to execute methods from the extension.

I'm using the Companion via USB and have never been able to use it with an extension.
