Function of phonetic symbols

The International Phonetic Alphabet strictly stipulates the principle of "one symbol and one sound", that is, "one phoneme, one symbol and one phoneme" is an essential pronunciation method for reading English words well.

In languages that use pinyin schemes, the same letter usually has several pronunciations in different words. For example, the "I" in English like and lit is phonetic with international phonetic symbols, which are [a? ] and [e], for example, A in bān (category) and bāng (modality) in Mandarin are [a] and [e] in the international phonetic alphabet respectively.
