Is the National Weather Service voice a real person?

Maybe, but it is delivered via prerecorded words then probably put together with VR. It’s a horrible sound. I get phone alerts about the weather but the voice sounds human.

The Weather Channel does the same thing – they had one of their people pre-record thousands of phrases, and then when they do the “forecast on the 8s” the artificial voice does all sort of reassembly of the wwords into actual sentences.

Yes. He’s the nephew of Mr. Speak-And-Spell.

It is a computer voice.
