the capital letter (phonetic order) of the whistle is: s z.

the syllable of the whistle is: shao zi.

a whistle refers to an object that can blow out a sharp sound, and it is used to give orders when gathering people, practicing or playing sports.

Phonetic order refers to the capitalization of the first letter of a syllable, that is, in the order of Chinese Pinyin.

syllables are phonetic units pronounced by phonemes (including consonants and vowels).

Extended information:

1. There are several common spelling methods for syllables:

1. Phonological spelling-take the vowels as a whole and spell them with the initials. Such as: h-ao→ (Hao).

2. Two spellings of initials-first, find the pronunciation position of initials, set the pronunciation posture, and then pronounce the vowels in one breath and spell them into syllables. For example, to spell bā (ba), first close your lips, hold your breath, pose for the sound of b, and then pronounce a in one gulp to become a syllable.

3. Three-syllable linking method-it is to analyze syllables with intermediate sounds into three parts: sound, medium and rhyme, and to link them into one syllable in pinyin. For example: q-i-áng→qiáng (strong)

4. Phonetic consonant and vowel connection method-it is to combine initials and vowels to form a phonetic component, and then spell it with subsequent vowels. Such as: gu-āng→guāng (light).

Second, the Chinese phonetic alphabet:

A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, W, X, Y, Z. V is missing (because it can't be sequenced and can't be read). However, in syllables, the vowel u can already be replaced by v.
