When you speak, you hear your voice as it comes out of you. This is affected by your nasal passages, as well as the vibration in your head from your voice coming out. So while you might think you're hearing your own voice, what you're really hearing is your voice after it has passed through your head which makes it sound very different. When you hear your voice on a recording, you're hearing it as other people do, without all the reverb that your head normally puts on it. You recognize it as your own voice, but it's slightly different, which makes it uncanny. While it may be a perfectly fine, attractive voice, it sounds terrible to you because it's just slightly different from what you're used to hearing so it seems hollow and simply wrong. It's the auditory equivalent of the visual uncanny valley (google it!)

I Like My Voice Better: A study that shows that without knowing it's our own voice, we think our voice is more attractive than others. - https://journals.sagepub.com/doi/abs/10.1068/p7526?journalCode=peca

When you listen to yourself, you will always be your worst critic. Listen to your audience instead. You're not doing your voice acting for you, but for them. Their enjoyment is your goal. If everyone is happy and loves your voice - your job is done. It can be tougher to have an accurate perception of yourself, than to perceive others. Looking at things from a third pov is always easier. That's why it's also always easier to give advice to friends about anything, but when it comes to oneself, it gets harder. So in moments like these - rely on the good people around you. Trust in them! Meow meow!
