It is common for people to notice that their voice sounds different when it is recorded compared to how it sounds to themselves. There are several reasons why this may occur:

1. The Doppler effect: When you hear your own voice in person, you are hearing the sound waves as they come directly from your mouth. When you hear your voice on a recording, you are hearing the sound waves as they are reflected off of surfaces in your environment before they reach your ears. This can cause a shift in the pitch of your voice, known as the Doppler effect.
2. The proximity effect: The proximity effect is a phenomenon that occurs when a microphone is placed close to a sound source, such as a person’s mouth. The proximity effect can cause the bass frequencies in a person’s voice to be amplified, resulting in a deeper-sounding voice on a recording.
3. Echo: The echo from a room or other space can affect the way your voice sounds on a recording. If the room you are in has a lot of hard surfaces, such as walls or a ceiling, it can cause your voice to sound more reverberant or echoey on a recording.
4. Headphones: If you are listening to your recorded voice through headphones, you may perceive your voice as sounding different due to the way that sound waves travel through the headphones and into your ears.
5. Personal perception: It is also possible that the difference in how your voice sounds recorded versus in person may be due to your personal perception of your own voice. People often have a mental image of what their own voice sounds like, which may not match up with how their voice actually sounds to others.

To reduce the difference in how your voice sounds recorded versus in person, you can try the following:

1. Use a high-quality microphone: Using a high-quality microphone can help capture the full range of frequencies in your voice and reduce the effects of the proximity effect.
2. Record in a room with minimal echo: Recording in a room with softer surfaces or using sound-absorbing materials can help reduce the amount of echo on a recording.
3. Listen to your recorded voice through headphones: Listening to your recorded voice through headphones can help you hear your voice more accurately and may help you perceive the differences between your recorded and in-person voices.
4. Practice: Practice listening to your recorded voice and compare it to how your voice sounds in person. With time, you may become more accustomed to the differences between the two.
