You may want to put questions about Dinki’s method in his thread: View Assist - Visual feedback for Assist voice assistant on an Android tablet (Install info provided on Wiki)
Or on his github page: dinki/View-Assist · Discussions · GitHub
But it sounds like you’re trying to mix his method with the HA companion app for android, which isn’t possible. His method bypasses the companion app and streams all audio continuously to the HA server for wakeword detection (using openwakeword) and STT processing.
If you want to use the HA companion app “assist” function, you’ll have to stick to the method described in the top post, which is currently incompatible with openwakeword, and uses snowboy for local wakeword detection instead.
