Human Speech Transmission Rates Averages 39 Bits per Second

Great read from Science breaking down Different languages, similar encoding efficiency: Comparable information rates across the human communicative niche:

Some languages were clearly faster than others: no surprise there. But when the researchers took their final step—multiplying this rate by the bit rate to find out how much information moved per second—they were shocked by the consistency of their results. No matter how fast or slow, how simple or complex, each language gravitated toward an average rate of 39.15 bits per second, they report today in Science Advances.
