I think I might have a personality disorder... I talk like people I meet?

[»mmmmmmmcm«]

So whenever i hear a person whos voice i like, i begin to uncontrollably mimic it. Ive been this way my whole life, my mothers always noticed. My boyfriends just started to.It's like i barely even know what my true voice sounds like. Its honestly embarrassing. Does anybody know if this is a condition and what its called, and if it can be treated?
