1. Definition: When you speak or read aloud, you have to send out a lot of syllables consecutively, and in the consecutive flow of speech, the syllables before and after each other affect each other, resulting in the change of some syllables' factors or tones, which is the speech flow sound change, or sound change for short. In Mandarin, tone change mainly includes the change of tone, soft voice, pediatricization and the change of tone word "ah".
2, (1) the upper tone of the change in the upper tone in the yinping, yangping, upper tone, go before the tone will produce a change in tone, read the complete upper tone of the original tone of the opportunity is rare, only in a single or at the end of the words, sentences, it is possible to read the original tone.
1) When the upper tone is in front of yinping, yangping, de-voicing, and light-voicing, i.e., in front of the non-upper tone, the rising tail of the second half of "14" is dropped, and the tonal value changes from 214 to 21 in the semi-upper tone, and the tonal value of the change of tone is depicted as 214-21. e.g.
2) When two upper tones are connected, the tonal value of the former one changes to 21 in the semi-upper tone. The tonal value of the previous upper tone becomes 35, i.e., the two upper tones are connected, and the tonal value of the previous character becomes the same as that of the yangping tone. The tonal value is depicted as 214-35. e.g.: beautiful měihǎo
The two upper tones are incompatible, the previous upper tone becomes yangping
The variation of three upper tones: There are two variations of the three upper tones:
Upper tones + (Shangsheng + Shangsheng) - half upper (21) + Yangping (35) + Shangsheng (214)
(Shangsheng + Shangsheng) + Shangsheng - Yangping (35) + Yangping (35) + Shangsheng (214)
(2) "One", "No"
In Mandarin, there are also "一"""七"""八", "一"""七"""八". "No", because in Mandarin, "seven" and "eight" have tended to be non-variable, and learning Mandarin only requires mastery of "one" and "no".
The single-word tone of "一" is 55, and the single-word tone of "不" is 51, which does not change when it is read alone or at the end of a phrase.
There are two kinds of tones for "一", "不"
1) The tone becomes 35 before the deprecatory syllable, which is the same as that of yangping.
2) Before the yinping, yangping, and shangsheng, i.e., before the non-devocalized syllable, the tonal value becomes 51, the same as that of the devoiced syllable.
3, light tone: Mandarin syllables have a fixed tone, but some syllables lose their original tone in words and sentences, and are pronounced as a kind of light and short fuzzy tone, and even the sounds and rhymes change, which is the light tone.
The light tone is not a fifth tone other than the four tones, but a special variation of the four tones, that is, a short and light tone under certain conditions.
Often these softly pronounced words are called softly pronounced characters, and words containing softly pronounced characters are called softly pronounced words.
4, pediatricization, is a syllable with a rolled tongue action, the rhymes undergo a sound change, become a rolled tongue rhyme (pediatricization rhyme).
(1) The main points: 1) "child" refers to the rolled tongue action, 2) "化" means that the rolled tongue action should be softly melted on the previous syllable, 3) 儿化韵听觉上是一个音节.
(2) The basic rule of paediatric pronunciation depends on whether the final phoneme of the rhyme is easy to roll the tongue.
1) When the last phoneme of the rhyme is a, o, e, ê, u, roll the tongue directly while pronouncing the rhyme, e.g., flower, bird, sing, white rabbit
2) When the rhyme is i, ü, add er after the original rhyme, e.g., chicken, ditty
3) When the rhyme is -i (before), -i (after), remove the rhyme, add er, e.g. Burrs, branches
4) When the rhyme is i, n, drop the rhyme, and add er if the main vowel is easy to roll the tongue, such as tree roots, a string of children, footprints, walking children
5) When the rhyme is ng, drop the rhyme, and add er if the main vowel is easy to roll the tongue, while the main vowel is nasalized. Such as bear, chirping
5 "ah" sound change training
"ah" attached to the end of the sentence is a tone auxiliary. When used at the end of a sentence or at a pause in a sentence, the intonation word "ah" is often influenced by the preceding syllable and produces a continuous pronunciation change.
The pronunciation of the "ah" sound change depends on the final phoneme of the syllable before the "ah".
Rules of sound change
1) When the final phoneme of the syllable before "ah" is the lingual vowels a, o, e, i, ü, the "ah" sound becomes ya (呀). Such as: painting ah really much ah write ah attention ah strive ah
2) the syllable before the final phoneme is u (including ao, iao), pronounced as "wow" (wa). Where do you live (zhùwa)?
3) If the final phoneme of the preceding syllable is n, it is pronounced as "na". How fresh the morning air is (xīnna)!
4) When the final phoneme of the preceding syllable is n, it is pronounced as "ah" (nga). This is a beautiful picture (liàngnga)!
5) If the final phoneme of the preceding syllable is -i, it is pronounced as "ah" (za); if the final phoneme of the preceding syllable is -, it is pronounced as "ah" (ra). I've been back and forth several times today (cìza)! What's the matter with you (shìra)!
