Yes, it is possible for your recorded voice to sound different from how you perceive it when speaking. When you speak, you hear your own voice primarily through bone conduction, which results in a deeper and richer sound. However, when you listen to a recording of your voice, you hear it through air conduction, which can make it sound higher-pitched and different to your ears.
The reason for this difference is that bone conduction enhances lower frequencies, giving your voice a deeper tone. In contrast, air conduction captures the sound waves in the environment, including higher frequencies that may make your voice sound higher-pitched on a recording.
It is important to note that your recorded voice is a more accurate representation of how others perceive your voice. People around you are accustomed to hearing your voice through air conduction, so the recording is likely a more accurate representation of how your voice sounds to them.
If you feel concerned about the difference between how you perceive your voice and how it sounds on a recording, it may be helpful to focus on the recording as a more objective representation and adjust your self-perception accordingly. Remember that everyone's perception of their own voice can be different from how others perceive it, and it is a common experience to find one's recorded voice surprising or unfamiliar.
