What to know
What to know about use iPhone as microphone
What 'use iPhone as microphone' usually means
Three intents hide behind this query: phone as a mic input for a Mac or PC, phone as a mic source for a Bluetooth or AirPlay speaker, and phone as a mic input for another iOS app via Inter-App Audio. This page covers the speaker case — the most common and the easiest to set up.
Pick the output before launching the app
Connect the Bluetooth speaker, AirPlay target, or wired adapter first. Once iOS sees an active audio output, any app you open will play through it. There is no output picker inside a live mic app — the operating system handles routing, which is why the order of steps matters.
Holding the iPhone for clear capture
The main mic sits at the bottom of most iPhone models, with secondary mics near the front camera and rear lenses. Hold the phone vertically about 15–20 cm from your mouth for speech and 5–10 cm for vocals. Speaking past the side of the phone instead of into it kills clarity faster than any setting change.
Common failure modes and quick fixes
Bluetooth speaker not appearing — toggle Bluetooth off and on in Settings. The app goes silent after an incoming call — the audio session was interrupted, restart live mode. No sound from the speaker — check that the volume slider is controlling the right output, since Bluetooth speakers usually have their own independent volume.

Yes. It is suited for simple announcements, classroom-style speaking, small gatherings, and practice sessions.
How do I reduce feedback?
Keep the speaker in front of you or away from the phone mic, and lower the volume if the speaker starts feeding back into the microphone.
Can I use it without connecting a speaker first?
