Many people feel uncomfortable when they hear their own voice in audio recordings. 
Your voice sounds deeper and richer when you speak but thinner and higher on recordings. The reason for the variance is this:
<ul>
<li>When listening to a recording of your voice, the sound travels through the air and into your ears. </li>
<li>When you speak, some sound travels through the air, but much of the sound is internally conducted through your skull bones and boosts the lower frequencies.</li>
</ul>

Your strange voice on a recording

Your voice on a recording really is a new voice. Because your voice is an integral part of self-identity, the mismatch between the voice you know and the voice you hear can be disturbing. You realise other people know your voice as something else.
Researchers found that patients with voice problems tended to rate the quality of their recorded voice more negatively than clinicians. If your inner self is criticising your voice on a recording device, you're probably judging yourself too harshly.

Why your voice sounds weird on recordings

That recording might sound funny to you, but others tuning in might not think so unkindly.

By <a href="https://www.popsci.com/authors/neel-bhatt-the-conversation/">Neel Bhatt/The Conversation </a>May 18, 2021

<ul><li><a href="https://www.popsci.com/science/">Science </a> </li> </ul>

<a href="https://theconversation.com/profiles/neel-bhatt-1222653">Neel Bhatt </a>is an assistant professor of Otolaryngology at the University of Washington. This story originally featured in <a href="https://theconversation.com/why-do-we-hate-the-sound-of-our-own-voices-158376">The Conversation </a>.

As a surgeon who specializes in <a href="http://scholar.google.com/citations?user=zZY5ezsAAAAJ&hl=en">treating patients with voice problems </a>, I routinely record my patients speaking. For me, these recordings are incredibly valuable. They allow me to track slight changes in their voices from visit to visit, and it helps confirm whether surgery or voice therapy led to improvements.

Yet I’m surprised by how difficult these sessions can be for my patients. Many become visibly uncomfortable upon hearing their voice played back to them.

“Do I really sound like that?” they wonder, wincing.

Some become so unsettled they refuse outright to listen to the recording—much less go over the subtle changes I want to highlight.

The <a href="https://doi.org/10.1111/j.1365-2273.2005.01022.x">discomfort we have over hearing our voices in audio recordings </a>is probably due to a mix of physiology and psychology.

For one, the sound from an audio recording is transmitted differently to your brain than the sound generated when you speak.

When listening to a recording of your voice, the sound travels through the air and into your ears—what’s referred to as “<a href="https://doi.org/10.1016/B978-0-12-385157-4.00121-4">air conduction </a>.” The sound energy vibrates the ear drum and small ear bones. These bones then transmit the sound vibrations to the cochlea, which stimulates nerve axons that send the auditory signal to the brain.

However, when you speak, the sound from your voice reaches the inner ear in a different way. While some of the sound is transmitted through air conduction, much of the sound is <a href="https://doi.org/10.1159/000266070">internally conducted directly through your skull bones </a>. When you hear your own voice when you speak, it’s due to a blend of both external and internal conduction, and internal bone conduction appears to boost the lower frequencies.

For this reason, people generally perceive their voice as deeper and richer when they speak. The recorded voice, in comparison, can sound thinner and higher pitched, which many find cringeworthy.

There’s a second reason hearing a recording of your voice can be so disconcerting. It really is a new voice—one that exposes a difference between your self-perception and reality. Because your voice is unique and <a href="https://www.npr.org/2019/07/15/741827437/finding-your-voice-how-the-way-we-sound-shapes-our-identities">an important component of self-identity </a>, this mismatch can be jarring. Suddenly you realize other people have been hearing something else all along.

Even though we may actually sound more like our recorded voice to others, I think the reason so many of us squirm upon hearing it is not that the recorded voice is necessarily worse than our perceived voice. Instead, we’re simply more used to hearing ourselves sound a certain way.

A study published in 2005 had <a href="https://doi.org/10.1111/j.1365-2273.2005.01022.x">patients with voice problems rate their own voices </a>when presented with recordings of them. They also had clinicians rate the voices. The researchers found that patients, across the board, tended to more negatively rate the quality of their recorded voice compared with the objective assessments of clinicians.

So if the voice in your head castigates the voice coming out of a recording device, it’s probably your inner critic overreacting—and you’re judging yourself a bit too harshly.
