Dictate Through Any Mic, Including Virtual Ones

Wispr Flow v1.6.580 lets you choose virtual and routing audio devices as your dictation mic, including Krisp, NVIDIA Broadcast, BlackHole, and VDI redirects.

Open Settings > Microphone or the Flow bar's mic switcher, then expand “Show other devices” to find virtual inputs. Automatic mic selection still uses physical microphones, so Flow won't automatically select a loopback device.
