How to test your microphone for Telegram calls and voice messages

Telegram Desktop has a Test microphone button in its call settings. On a phone, the simplest check is a voice message to Saved Messages, your private chat with yourself, which you can play back. Then compare with a short browser recording made with the same microphone.

Check my microphone for Telegram calls

Check my microphone for Telegram voice messages

MicProbe’s Telegram tests approximate microphone processing locally in your browser. They do not connect to Telegram, send a message or measure what the other person hears.

Test the microphone in Telegram Desktop

Open Telegram Desktop’s settings and find the call settings. Choose your microphone under Input device, check Input volume and select Test microphone, then speak. The same section sets the output device and has a link to your system’s sound settings.

Recent versions of Telegram Desktop also let you choose the microphone for voice messages, and change audio devices from the window of a one-to-one call. See the Telegram Desktop changelog.

Record a test voice message

Open Saved Messages, so the test reaches nobody else.
Hold the microphone button and speak a few sentences at your usual distance. To record hands-free, swipe up to lock the recording.
Once the recording is locked, you can pause and resume it, and trim its start and end before you send it.
Send it, then play it back. Delete it afterwards if you like.

Telegram describes locking, pausing and trimming in its announcement of voice message trimming.

Check noise suppression in voice chats

Telegram documents noise suppression for group voice chats, with a setting to turn it off in the voice chat’s settings. It does not document a separate setting for one-to-one calls. If people in a voice chat say your voice sounds clipped or thin, compare it on and off. See Telegram’s group video calls announcement.

Compare with a browser recording

Open MicProbe and select the Telegram call test or the Telegram voice message test, then choose the same microphone you use in Telegram. Follow the recording guide, then use Play to hear the saved sample. Keep your speaking distance, room and listening device the same for both checks.

A named MicProbe test is a local approximation, not a recording from Telegram. The call test takes its settings from a Telegram Web group call; one-to-one calls were not measured. The voice message test follows voice messages from the Telegram web app; the phone and desktop apps may record at other settings.

What does the difference tell you?

Both recordings sound wrong: start with the microphone, its position and the room. Follow the guides for low volume, muffled speech or static and buzzing.
The browser recording is clear, but Telegram calls sound worse: check which microphone Telegram uses and compare noise suppression on and off. Then read why a clear recording can sound worse in a call.
Words go missing in calls: use the cutting-out microphone guide to separate missing words in your recording from interruptions in the call.

If Telegram cannot hear your microphone

Check the microphone permission first. On iPhone, open Settings → Privacy & Security → Microphone and turn on Telegram. On Android, open Settings → Apps → Telegram → Permissions and allow Microphone. On Windows, open Settings → Privacy & security → Microphone and turn on Let desktop apps access your microphone; on a Mac, use System Settings → Privacy & Security → Microphone. In Telegram Web, allow the microphone when your browser asks.

If calls sound poor rather than silent, Telegram notes that saving data on calls can lower sound quality and that a proxy for calls may make quality worse. Try a call without them.

If you use a Bluetooth headset, sound playing through it can change when its microphone is active; see the Bluetooth microphone guide.

Common questions

Does Telegram have a mic test?

Telegram Desktop has a Test microphone button in its call settings. The phone apps do not document one; a voice message to Saved Messages lets you hear how you sound.

Why does my voice sound different in a call than in a voice message?

A call is sent live and can change with the connection. A voice message is recorded first and sent as a file, so a weak connection delays it instead of cutting words out. Compare both on the same microphone to see which one changes.

Does MicProbe test Telegram’s servers?

No. Its Telegram tests use a local approximation. The connection check sends a sample voice to a nearby Cloudflare server and back, not through Telegram’s servers. Read what MicProbe measures and what it cannot check.

For other apps, see the WhatsApp, Discord and Zoom mic test guides.
