What Is Speech Production?

Voice, the material shell of language, is the external form of language, and it is the symbol system that most directly records people's thinking activities. It is a socially meaningful sound from the human vocal organs. ^[1] The physical basis of speech mainly includes pitch, intensity, length, and color, which are also the four elements that make up speech.

Voice refers to the meaning that is issued by humans through the vocal organs and is used for social purposes

There are three differences between speech and various other sounds:

First of all, speech has physical properties, and like all sounds in nature, it is a kind of

The speech signal is transmitted from one party to the other, and passes through the three links of pronunciation-transmission-perception, which respectively correspond to the three physical, physical, and psychological attributes of speech, from phonology-acoustics-hearing The study of three disciplines of phonetics marks the progress of people's study of phonetics.

There are 410 syllables in Mandarin, and about 1200 tones have other syllables. If you use Mandarin to press the same tone (equivalent to no tone)

Speak good mandarin

410 speech types), people cannot understand such "Mandarin" at all, so the 410 speech types cannot support the existing number of Chinese characters used in Mandarin. Mandarin (1200 voice types) spoken in different tones can be heard without difficulty in non-refined situations, while Mandarin is hardly audible in fine-articulated situations (such as reading Tang poetry and Song poetry). The number of Chinese characters used in fine and non-fine situations is exactly the same, which clearly shows that the phonetic system of the language of Mandarin does not have the ability to support the entire Chinese character system. Regardless of any dialect in Chinese, the number of Chinese characters supported by its phonetic system should be three times its total number of phonetic types. The basis is that a simplest standard sentence contains three components: subject, predicate, and object. Homophones appear in each of the three components, so the sentence must not be audible. Because when the amount of Chinese characters used in a Chinese dialect is three times its total number of phonetic types, each phonetic must bear 3 different semantics on average, and the subject, predicate and object are assigned to this simplest standard sentence. All of the mixed meanings appear, so that the entire sentence completely loses the uniqueness of the logical concept, and it also loses the ability of the brain's error correction mechanism to resolve and correct homophonic mixed meanings, so that the speech cannot be understood by the listener. Therefore, the credible calculation results are: Mandarin, a Chinese dialect, can support a maximum of 4,500 Chinese characters.
