macOS gates each of these. Click Open Settings, flip the toggle next to Lirelle, then come back — this page checks automatically.
Lirelle records your voice for dictation and meetings. Audio is transcribed on this Mac; nothing is uploaded.
Used to paste the transcript into the app you're working in and to register the dictation hotkey.
Lets Lirelle watch for the modifier hotkey (Right Option by default) so you can hold-to-talk anywhere.
Required only to capture system audio from the other side of a call. Dictation works without it.
