Is it natural and correct to say "talk via audio" meaning to actually talk to someone over the phone rather than text?

Question

Is it natural and correct to say talk via audio meaning to actually talk to someone over the phone rather than text? For example:

Do you prefer to talk via text or audio?

If it sounds off, would it be more natural to say talk via phone call?

Answer 1

Using audio here is awkward.

---

Informally, assuming the right context, I would drop talk and via altogether, and replace audio with phone:

Do you prefer text or phone?

It can also be phrased differently:

Do you prefer texting or calling?

---

More formally, I would replace talk with communicate, and I'd probably replace via with over:

Do you prefer communicating over text or phone?

Or there is the following variation:

Do you prefer writing texts or making phone calls?

Answer 2

I'd talk via audio over the internet but I'd only ever talk "on the phone". I'm British, I've heard Americans talk "over the phone" but not "via audio" when they mean phone.
