Currently available voice changer technology primarily focuses on altering the timbre or pitch of a person's voice, rather than reproducing the exact sound of one's own voice as it sounds to them. While voice changer software and apps can modify your voice to some extent, achieving a precise replication of how your voice sounds to you is challenging.
The perception of our own voice is influenced by a combination of bone conduction, which occurs when sound vibrations travel through the bones of our skull, and air conduction, which is how sound waves reach our ears through the air. This dual pathway makes our voice sound deeper and richer to ourselves than it does to others when recorded and played back.
Unfortunately, replicating this subjective perception of your own voice accurately would require highly specialized equipment and techniques that are not readily available in consumer-level voice changer products. The technology to achieve such a precise replication may exist in certain research or professional settings, but it is not commonly accessible to the general public.
