ELI5: Why does my voice sound different (and awful) when it's recorded and I hear it replayed?

I recently decided to change my voicemail greeting, and hearing my own voice through my phone speaker made me cringe. Why does it sound different, and why do I not hate hearing it when I'm speaking?

When you normally hear your own voice you are hearing two distinct things. First, you hear the normal sound waves coming through the air, into your ear just like everyone else. Second, you are hearing the bone conduction. This is the vibration that your voice causes in your bones that gets transferred to your inner ear. The combination of these two is what you think of as your own voice. Other people only hear the first part.

It sounds so awful to you because it sounds kind of like your voice, but slightly off. The familiar thing that is changed just a little is more disconcerting than a completely different voice.
