And, I've notice most always sound...well...worse when on Skype or on the phone than in person. If that's the case, just text and only talk in calls if its absolutely important. That helped me a lot.
This might also have to do with the way that everyone kind of hates the sound of their recorded voice.
Like, have you ever heard your own voice played back in a video or something and thought "Wow,
that's my voice? I sound horrible". Turns out, there's a good scientific reason as to why just about everyone hates the sound of their own recorded voice until they get used to it.
You see, when you hear your own voice as you speak, sound is traveling in two ways -- the first is through the air to your ears, and the second is directly from your throat, through your bones, and into your inner ears. This creates a unique blend of sound that
only you can hear. Everyone else hears only the sound that travels through the air. That's why people often think their voices sound weird when recorded; you're only hearing the part of your voice that travels through the air, the way everyone else usually hears it, and it sounds strange to you because you're not used to it.
I don't know if your self-consciousness about your voice was in any way caused by hearing it recorded, OP, but, if that is the case, I figured this would be a useful bit of science to share with you. Your voice might sound awful to you when you play it back, but only because it's off from what you're used to. (Oh, and the only-travels-through-the-air component of people's voices tends to be slightly higher-pitched than the unique blend that only the person speaking can hear. Make of that what you will.)
