Which is the fastest language in the world?

The fastest language in the world is Japanese, and here’s the reason.

Equality of languages

Languages should be equally great in their functionality, as good things can be learned from other languages and bad things can be abandoned in the language, so that languages are equally useful while meeting the needs of their speakers Specialize.

Information rate of languages

The purpose of the language is communication.If they are to have the same functionality, their information rate, which is the product of information density and syllable rate, should be the same.

In fact, the information rate of languages is not absolutely the same, but at least similar as shown in the table below.Note, however, that the language functionality does not come purely from this, which will be discussed later.

Characteristics of languages

Languages typically have a relative information rate of 0.90 or more, with English being the highest and Japanese the lowest.


The reason why English has such a high information rate is probably the simplicity of the words and the moderate pronunciation speed that makes it better overall than Mandarin.

Unique words are often created in English to express new concepts, while compound words can be used in other languages to achieve differences in information density.


The slowness of Mandarin is due to its four tones.Therefore, words should be spoken more clearly so that the listener recognizes the sounds and slows down the pronunciation speed of Mandarin.


The reason why Japan has the lowest information rate and the fastest pronunciation speed is the same, namely the low information density.Because the language is similar in functionality, the low information density is compensated by the fast pronunciation speed to make it comparable to other languages.

The low information density in Japanese is due to the limited number of syllables, as the presence of complex syllables is not possible in Japanese.To use a smaller number of syllables, a longer combination of syllables should be used for pronunciation of words so that the sounds of words can be distinguished. On the other hand, the simple syllables can be quickly recognized in Japanese, so the speaker’s pronunciation speed can also be faster.

Nature of language

Let us now return to the above discussion: How can languages be the same in functionality at different information rates?

An important point is that language is the representation of our mind and that our minds are equal, so languages should be the same.

There are two aspects of languages, oral and written, that form the functionality of languages.Since languages have the same functionality, a language that is stronger in oral form is weaker in writing, and this is indeed the case.

European languages

English is weaker due to the incoherence of the pronunciation and the written form of words, so speakers have to spend more effort reading and writing English.By contrast, other European languages spell as they are spoken, so they are better in writing than English.

The inconsistency in the pronunciation and written form of words makes all European languages the same in functionality, and the Asian languages offer another way to achieve a better written form, so that they can also be used in the European languages. in functionality.

Asian languages

Chinese and Japanese share the common fonts of Kanji, which is a better font.Kanji is used to represent a word, but it is recognized like images, while European words are recognized by letters. Therefore, Kanji in Chinese and Japanese makes the recognition of written words more efficient than European languages.

The benefits of kanji are more obvious in Japan because of their different information density.Chinese have been using kanji in the style of a kanji since Kanji was created by the Chinese. The only advantage of Kanji is the recognition of words in written form, which bypasses slowness in oral form and is faster than European words.

Kanji brings enormous benefits to Japanese.Because Kanji is native to Chinese, a language with a high information density, a kanji can compress Japanese words with a long syllable combination into an icon, which makes it faster to recognize written words in Japanese. The advantages of Kanji in recognition also give Japanese a written boost.


After all, languages are the same in their functionality, because the speed of recognition of our mind is crucial.
