How many words per minute does the average person speak?
We talk continuously every day, but how many words can you say a minute? Are you sure you know?
According to the research, there are languages that speak faster, but when multiplying the speed by the amount of information in each syllable, they found that: Regardless of the language, whether the speaking rate is fast or slow, the speed is Information conveyed in each sentence is at an average of about 125 to 150 words per minute.
In the past, many linguists have suggested that information-rich languages (more verb tenses, masculine and feminine nouns, for example) are spoken more slowly, while "less informative" languages such as Italian is spoken faster by humans. But until now scientists have no evidence for that claim.
They started by calculating scripts from 17 different languages, including English, Italian, Japanese and Vietnamese. They calculate the amount of information in a sentence in bits. As a result, Japanese, with 643 syllables, possesses 5 bits of information per syllable. Whereas English has 6949 syllables but only 7 bits of information per syllable. Scientists discovered that Vietnamese is one of the most information-rich languages, each syllable contains 8 bits of information, with 6 tones (accents) allowing to change syllables.
Next, the researchers spent three years recording 10 people speaking 14 languages and finding tapes for the other three. A sentence was translated into their mother tongue, then the scientists calculated how many seconds the sentence took to read, and then the speed of syllables per second. There are languages that speak faster, but when multiplying the speed by the amount of information in each syllable, they found that: Regardless of the language, whether the speed of speech is fast or slow, the speed at which information is conveyed in each sentence is at an average of about 39.15 bit/s.
