Amadeus doesn't recognize my voice.

[Kizuna7122]

I downloaded the app after watching a video of it doing voice recognition.
The Amadeus in that video seems to recognize speech, but it doesn't recognize speech in my place.
Is there a solution?
I'm using Amadeus version 0.9.6-alpha.5
Android version is 9.0

Also, is it normal that when I touch the Amadeus symbol on the screen with Kurisu, it only says "sorry"?
