Information transmission speed by language is about 40bps in any language
The Italians are said to be “the fastest in the world” and speak up to 9 syllables per second. On the other hand, the same European Germans have 5-6 syllables per second, and there is a big difference in speaking speed. However, research has shown that the transmission speed of information in any language converges to about 39 bits (39 bps) per second, which is about twice that of Morse code.
Different languages, similar encoding efficiency: Comparable information rates across the human communicative niche | Science Advances
Human speech may have a universal transmission rate: 39 bits per second | Science | AAAS
The following 9 languages and 17 languages were surveyed.
・ Indo-European languages: English, French, German, Italian, Spanish, Catalan, Serbian
・ Ural languages: Finnish (Suomi), Hungarian (Majar)
・ Turk: Turkish
・ Thai-Kadai language: Thai
・ Austrian Asian: Vietnamese
・ Sina Tibetan: Mandarin, Cantonese
・ Korean language: Korean (Korean)
・ Japanese family: Japanese
In the research, sample sentences written in each language are prepared to see how long it takes to read the sentences in the above 17 languages. The speed of reading by the subject and the information density of the language were calculated, and the density of information transmission was calculated.
Then, as mentioned above, the speaking speed varies greatly depending on the speaker, while the information density by language is 4.8 bits per syllable in Basque, while Vietnamese has a difference of 8.0 bits per syllable. Has converged to an information transmission rate of approximately 39.15 bits per second in both languages. The initial modem transfer rate is 110 bps, and the average Internet information transfer rate is over 100 Mbps (100 million bps) today.
According to François Peregrino, co-author of the paper, evolutionary linguist, linguistic science has so far focused on the complexity of grammar and the information transfer rate has often been overlooked.
Regarding the conclusion that “every language has the same information transmission speed”, Mr. Peregrino expressed the idea that the brain is a bottleneck. In addition, people know that listening to 120% speed sound does not hinder understanding, so the bottleneck is not the “listening to voice” part, but the stage of thinking together It has been.
