I am a linguist. I can often tell just by the tone of someone's voice their ethnicity. Word choice, pronunciation and expressions used...it's not that difficult. If you knew me, you would know why I can tell such things. I frequently tell the phone bank people where they're from before they tell me. They are SURPRISED.

Lot of road noise in the background, so he probably is driving a truck. He's here in Texas and trying to buy a handgun.

I can almost always tell a black person’s voice from a white person’s voice.

There are distinct qualities about 90% of the time.

I would have gone with:

Can I ax you how did you know he was black?

"How did you know he was black?"

His voice, little accents here and there, language use, etc. Just like you can tell a Brit, southern accent etc. Practice a little ...I'm sure you can get the idea.
