Why Your Recorded Voice Sounds Different | How Bone Conduction Works and How to Check Your Real Voice

Only your own voice reaches you by two paths

Other people’s voices reach your ears as vibrations in the air. That is a single path. When you speak, however, a second path is added: the vibration of your vocal cords travels through your skull and surrounding tissue directly to your inner ear. What you normally think of as “your voice” is a mix of the two.

A recording captures only the vibration of the air in front of the microphone. So a recording of your voice is almost the same as what others hear, and the voice you hear every day is the unusual one. It is more accurate to say “something added to my everyday voice is missing from the recording” than “the recording sounds wrong”.

Why recordings sound higher and thinner

The path through bone and tissue carries low frequencies well. The voice you hear yourself therefore has a thick layer of bass, which makes it sound fuller and calmer than it really is. A recording drops that layer entirely, so by comparison it sounds higher, thinner and more nasal.

• If you cover your ears and talk, your voice sounds muffled and louder. You have weakened the air path and raised the share of the bone path. This lets you feel how bass-heavy bone conduction is.
• The same reason explains why you barely notice your own voice changing when it breaks or when you have a cold: what you hear always includes the bone-conducted part.
• The discomfort isn’t only about sound. Hearing your speech habits, drawn-out endings and pauses from the listener’s side for the first time also has a big effect.

Recording conditions change the sound too

Bone conduction is the biggest factor, but other things change how a recording sounds. If your voice seems different every time you record, these are the likely causes.

The last two are the easiest to mix up. Your voice played through a phone speaker sounds even thinner because of the device. If you want to judge how you come across, listen back on earphones.

Steps to check how you really sound

1. 1

   Start a mic test and watch the input level

   When you start a mic test in your browser, it shows the name of the detected device and the input level. First check that the level moves when you speak.

2. 2

   Adjust so the level stays in the right range

   Below −30 dB is too quiet, and above −6 dB risks clipping. Adjust your distance from the mic or the input volume in your OS to stay between them. The result is also shown on screen.

3. 3

   Record for just 15 seconds

   You can record up to 15 seconds. Read something close to what you actually say, like a greeting and a self-introduction. The recording is processed only on your device and is never sent to a server.

4. 4

   Listen back on earphones

   Playing it through speakers can cause feedback as the mic picks up the sound. Use earphones. Listen for volume, speed and how you end sentences rather than for pitch.

5. 5

   Use the monitor feature while you speak

   Monitoring your own voice lets you hear only the air-conducted sound in real time as you speak. It gives you a feel for speaking without bone conduction mixed in, which is useful for adjusting how you talk. Earphones are a must here too.

6. 6

   Record again under different conditions

   Re-record with a different distance, room or microphone and compare. You can download the recordings, and lining them up side by side makes the differences clear.

Adjustments that make you easier to understand

What you can fix after listening back is not your voice quality but how you speak and your equipment. If people often ask you to repeat yourself in online meetings or interviews, check these in order.

• Volume: if you speak too quietly, the listener has to turn you up, which also amplifies background noise. Moving closer to the mic is more reliable.
• Speed: fast speech doesn’t mix well with call compression and gets crushed from the ends of words. Simply keeping sentences short changes how well you come across.
• Sentence endings: trailing off at the end of sentences is barely an issue in person, but on calls the last few words disappear.
• Fixed position: if you move while you talk, your volume rises and falls. Decide where the mic goes and stay there.
• Background noise: keyboard clicks and air conditioning may drop out of your awareness, but the mic picks them up at full volume. They are the classic things you only notice on a recording.

It takes time to get used to your recorded voice, but the strangeness fades with repeated listening. Listen back a few times until it settles, then adjust only how you speak on the assumption that “this is what they hear”. That is the most efficient way forward.

FAQ

Why does my recorded voice sound like someone else?

When you speak, the sound reaching your ears through the air is mixed with sound from your vocal cords that travels through bone and tissue to your inner ear. That bone path carries low frequencies well, so your voice sounds deep and full to you. A recording captures only the air-conducted sound, so that bass disappears and you sound higher and thinner. It isn’t a fault in the equipment.

Which is my real voice: the recording or what others hear?

What others hear is close to the recording. The bone-conducted part can only be heard by the person speaking. So when you want to check how your voice comes across, go by the recording rather than how it sounds in your head. The playback device also changes the impression, though, so listening back on earphones rather than a speaker gets you closer to how you actually come across.

My voice sounds muffled when I record. Can I fix it?

If you are too close to the mic, the bass is boosted and you sound muffled. Keep about 15–20 cm from your mouth and aim the mic slightly off to the side rather than straight at your mouth. In rooms with hard walls, reflections also blur the sound, so recording somewhere with fabric or curtains helps. Recording at different distances with a mic test makes the difference clear.

Is there a way to hear my own voice while I speak?

The mic test’s monitor feature plays back your input as it comes in, so you can hear your voice without the bone-conducted part while you talk. Doing this through speakers causes feedback as the mic picks up the playback, so always use earphones. It is good practice for adjusting your speaking speed and how you finish sentences.
