So how much will a phone distort your voice?

Depends on the bandwidth and the quality of the recording. The higher the bits-per-second, the more accurate the recording will be.

If you remove the ‘so’ from your question it will improve it 99%. Very very very few sentences should begin with ‘so’ or ‘ok’.

You first asked about a phone, then recordings. If you want to distort your voice you can buy a device for that. You probably have a teacher who could give you a really good full five-minute answer. I’m sure there is information online as well. I hope you answer this and all of your other life questions. Best wishes.

Um. Why would I want to distort my voice? LOL!!!!!!!!!!!!!
