Interesting excerpt:

De Boer agrees that our brains are the bottleneck. But, he says, instead of being limited by how quickly we can process information by listening, we're likely limited by how quickly we can gather our thoughts. That's because, he says, the average person can listen to audio recordings sped up to about 120%—and still have no problems with comprehension. "It really seems that the bottleneck is in putting the ideas together."

Ah, here's a link to the paper!

Theoretically speaking you do need to take phrasal tone into account, but in practice the difference is negligible - because most languages reinforce questions through syntactical and/or lexical means - particles, pronouns, subject-verb inversion, etc.

I'll for sure dig a bit deeper on the links, but for me it's still very counter intuitive to estimate information density of spoken word just by the count of syllables.

E.g. I can vary the sentence 'I need help' in so many ways. I can mumble it to a close sitting person to imply secrecy, I can say it in a desperate voice to show psychological distress, I can increase the volume to indicate urgency etc. And all that doesn't even consider body language, mimics etc. which are all part of the information flow. And I'd guess that body language varies a lot from country to country.

...ah. The rabbit hole of paralinguistic information - all those bits of info that aren't part of the language itself, but still found alongside it. It's a big deal as you noticed, but really hard to quantify, so I don't blame the authors for leaving it off.

But lot of very common ones like Spanish and Portuguese don't. The difference between a statement and a question is exclusively the tone in both.

That's only for yes/no questions. Open-ended questions start with a pronoun in both, as typical for Indo-European languages. Portuguese example:

A cor do cavalo é cinza. // the colour of-the horse is grey.
Qual é a cor do cavalo? // which is the colour of-the horse?
Qual que é a cor do cavalo? // which that/what is the colour of-the horse?

#2 is the standard way to phrase a question, but #3 is really common in informal speech.

And colloquially sometimes you even see yes/no questions getting some "random" emphatic word, like:

A cor do cavalo é cinza, né? // the colour of-the horse is grey, innit?
Ma[s] a cor do cavalo é cinza? // but the colour of-the horse is grey?

They do change the nature of the question slightly (the first one sounds rhetoric, the second one as if there was conflicting info), but the main reason they're added is to reinforce the phrasal tone as a question marker.
