I am not a trans but I want to change my voice

I posted a lot about that I hate my voice and that it sounds childish and bad … I really cringe of my voice everytime I talk

People always can’t judge my voice when I post because they don’t hear it… so I will put a link to a voice records here

I am recording in my room and with low energy so ofc it will sounds a bit different from my voice with my friends or in the street , but anyways I think now you can judge how my voice sounds

My question here what changes I can do to my voice ? I feel that I hate the voice itself and the way I talk also , but also feel that I can’t change both
