🔥 Why This Happens (Quick Answer)
If people cannot hear you on your iPhone, the microphone may be blocked, muted, connected to a Bluetooth device, denied permission inside an app, or affected by a temporary software problem.
Your iPhone uses different microphones for regular calls, speakerphone, FaceTime, Siri, and video recording. That means the problem may happen only during one type of call.
🚀 Quick Fix (Try This First)
✔️ Make sure the call is not muted.
✔️ Remove the case and clean the microphone openings.
✔️ Disconnect AirPods and other Bluetooth devices.
✔️ Test your voice using Voice Memos.
✔️ Restart your iPhone.
1. Make Sure the Call Is Not Muted
It is easy to tap the Mute button accidentally during a call.
When Mute is enabled, you can still hear the other person, but they cannot hear you.
Fix:
Look at the call screen and make sure the Mute button is turned off.
2. Remove the Case and Accessories
A poorly fitted case, screen protector, or attached accessory may partially cover one of the microphones.
Fix:
Remove the case and any attached accessories, then make another test call.
3. Clean the Microphone Openings
Dust, lint, makeup, and debris can block the microphone and make your voice extremely quiet or muffled.
Fix:
Use a soft, dry electronics brush to clean around the microphone openings gently.
Do not insert pins, sharp tools, liquids, or compressed air into the openings.
4. Disconnect Bluetooth Devices
Your iPhone may be using the microphone on connected AirPods, headphones, a vehicle, or another Bluetooth accessory.
If that microphone is too far away, blocked, or malfunctioning, callers may not hear you.
Fix:
Temporarily turn off Bluetooth and make another call using the iPhone’s built-in microphone.
5. Test Regular Calls and Speakerphone
Regular calls and speakerphone may use different microphones or audio processing.
Fix:
Make a test call normally, then turn on speakerphone.
If people can hear you in one mode but not the other, one microphone may be blocked or damaged.
6. Test the Microphone With Voice Memos
Voice Memos helps determine whether your iPhone can record your voice outside of phone calls.
Fix:
Open Voice Memos, record yourself speaking for several seconds, and play it back.
If the recording is silent, muffled, or extremely quiet, the microphone may be blocked or malfunctioning.
7. Test the Front and Rear Cameras
Your iPhone uses different microphones while recording with the front and rear cameras.
Fix:
Record a short video using the rear camera, then record another using the front camera.
Play both videos and compare the sound.
If only one recording has poor audio, one specific microphone may be affected.
8. Check Microphone Permission for Calling Apps
If people cannot hear you only in FaceTime, WhatsApp, Messenger, or another calling app, microphone permission may be disabled.
Fix:
Go to:
Settings > Privacy & Security > Microphone
Make sure microphone access is enabled for the affected app.
9. Restart and Update Your iPhone
A temporary software or call-routing problem may prevent the microphone from working correctly.
Fix:
Restart your iPhone and test another call.
Then check for available software updates under:
Settings > General > Software Update
10. Check for Microphone or Network Problems
If your microphone recordings sound normal but callers still cannot hear you, the problem may involve the cellular connection, Wi-Fi calling, or the calling app.
Hardware trouble is more likely when Voice Memos and videos also have missing or distorted sound.
Fix:
Try another call from a different location and switch between cellular calling and Wi-Fi calling when available.
If the microphone fails across calls, videos, and Voice Memos, the iPhone may need professional inspection.

💡 Final Thoughts
When people cannot hear you on an iPhone, the cause is often something simple: the call is muted, Bluetooth is connected, a case is covering the microphone, or debris is blocking an opening.
Testing regular calls, speakerphone, Voice Memos, and videos can help identify whether the issue affects one microphone or the entire audio system.
If your voice is missing or distorted in every recording method, especially after a drop or liquid exposure, the microphone may need professional inspection.
