This also probably varies greatly by language.
Someone speaking a language like Chinese, where most of the words are single syllables, could probably speak a lot faster than someone speaking, say, German, where the words are often super long.
That's just my mostly uneducated guess, though. It'd be interesting to see some real-world comparisons of this.
I don't have a source for this, but at some point I read a paper which indicated that for languages with a lower information density per syllable, people speak faster, and vice versa, so on average all humans communicate the same amount of information per second.
I've somewhat noticed the same thing with just regional accents of english. The faster the accent, the more "filler" the speech contains.
> 500,600 words per minute
I realise 500/600 looks like 5/6, but 500,600 reads to me as 500600. Maybe | is a good unambiguous character to use for "or".
Dashes are customarily used for ranges. 500-600 wpm; 35-75 Kph; 2-3 grams. While a / can be used for words "and/or", using it with numbers leads to confusion with fractions: 2/3.

As Y_Y already indicated:
> I realise 500/600 looks like 5/6 ….
If we're going to fuss about typography, these things:
> 500-600 wpm; 35-75 Kph; 2-3 grams.
are hyphens, and you want an en-dash: 500–600 wpm instead of 500-600 wpm.
Average speaker is 150, an auctioneer is 250-400, the fastest person. The fastest talkers male and female can recite over 500,600 words per minute.
People can certainly and some people while exited/upset may.
