The notation of A o e i u ü is sequential, with I and U appearing at the same time. The vowels after the notation are deleted when they touch JQ X Y. As long as there is an A in the vowel, mark it on A, find o e if there is no A, mark it on O if there is an O, and mark it on E if there is no O..
If there are two vowels (vowels), and the first vowel (vowel) is I, U or U, the tone is marked on the second vowel (vowel). In other cases, the tone should be marked above the first vowel (vowel).
Pinyin tone refers to the tone in Putonghua, which is usually called four tones, that is, even tone (the first tone), and is represented by "ˉ", such as lā; The second sound of the upper voice is represented by "ˊ", such as lá; Phonetically (the third sound), it is represented by "ˇ", such as l m:de-voudent (the fourth sound), represented by "ˋ", such as; Pull.
Extended data tone symbol:
The methods of flat tone (ˇ), rising tone (ˇ) and rising tone (ˇ) are used to eliminate sound (ˋ) and light tone (non-standard). This method solves the problem of distinguishing Chinese characters with different tones. For example, Ma mā (flat tone), Ma má (rising tone), Ma Mǐ (rising tone), Ma Mǐ (falling tone) and Ma mɑ (softly out of tune).
Implementation method:
(1) Replace the horizontal tone (ˇ) symbol with the number 1, because the horizontal tone is the first tone. For example, pinyin P and n y and N, according to this method, it is pin 1 yin 1.
Example: The pinyin for "ah, ah, ah, ah" is "ā". In this way, the pinyin of "A" is "A".
Ai Yi Zhong's pinyin is "āi". In this way, the pinyin in Ai Ai Ai is "ai 1".
(2) Use the number 2 to replace the sign of rising tone (ˇ), because rising tone is the second sound.
For example, the pinyin for cancer is "ái". In this way, the spelling of cancer is "ai2".
(3) Use the number 3 to replace the symbol (ˇ) of the upper sound, because the upper sound is the third sound.
For example, the pinyin of Ai Ai Ai is "m: i". In this way, Aiai's pinyin is "ai3".
(4) Replace the ˋ-tone symbol with the number 4, because the tone is the fourth tone.
Example: Love, love, love, love, love, love, love, love, love, love, love, love, love, love, love, love, love, love, love, love, love, love, love, love, love, love, love, love, love, love.
(5) Use the number 5 instead of light tone, because light tone is the fifth tone.
Example: the pinyin of the word ah is "ɑ". In this way, the pinyin of the word A is "a5". The pinyin of the word Baba is "Ba". In this way, the pinyin of the word Baba is "ba5".
(6) Description: According to the above implementation method, the tone (number) is marked after the syllables with numbers. For example, the establishment.
