Talk to Mira on Android

I have MiraCheck on my iPad and on my Android phone (as a backup device). I can enable Talk to Mira on both devices, but it only works on iPad. My Android phone enables it successfully but will not recognize my voice.

I found a couple of posts elsewhere mentioning that voice recognition on Android is much more difficult than iPad. If it can’t work, why is there a toggle for it? If it should work, is there anything I can try to fix it?
