If you have any links to research supporting this, I would be interested.
> The mean Listening Rate was 56.8, which corresponds to 309 WPM. Given that people typically speak at a rate of 120-180 WPM, these results suggest that many people, if not most, can understand speech signifcantly [sic] faster than today’s conversational agents with typical human speaking rates.
While there was some difference between the visually-impaired and normal-vision respondents, I don't think it's enough to matter to the thesis of my post:
> [...] The mean Listening Rate for visually impaired participants was 60.6 (334 WPM) while for sighted participants it was 55.1 (297 WPM).
From page 4 of 12 of the PDF you linked to, “Rhyme test: measures word recognition by playing a single recorded word, and asking the participant to identify it from a list of six rhyming options (e.g., went, sent, bent, dent, tent, rent). We used 50 sets of rhyming words (300 words total), taken from the Modifed Rhyme Test [27], a standard test used to evaluate auditory comprehension.” The word list research used is on page 30-31 of 55 of this PDF:

If true, test appears to not even measuring word recognition, it’s more accurately measuring a single phoneme recognition. If the listener correct picks the correct phoneme from a multi-choice list, researchers assume person would hear and understand 100% of any expressions received at that rate of speed; which in my opinion is clearly flawed.
I would be the first to agree that testing listening comprehension rates is hard to do, hence why I asked to review research, but to me, unless I am misunderstanding something, unclear how this research actually provides any meaningful observations.
