Standard Chinese phonology

This article summarizes the phonology (the sound system, or in more general terms, the pronunciation) of Standard Chinese (Standard Mandarin). Standard Chinese phonology is based on the Beijing dialect of Mandarin. Actual pronunciation varies widely among speakers, as they introduce elements of their native varieties (although television and radio announcers are chosen for their ability to produce the standard variety). Elements of the sound system include not only the segments – the vowels and consonants – of the language but also the tones that are applied to each syllable. Standard Chinese has four main tones, in addition to a neutral tone used on weak syllables. This article represents phonetic values using the International Phonetic Alphabet (IPA), noting correspondences chiefly with the Pinyin system for transcription of Chinese text. For correspondences with other systems, see the relevant articles, such as Wade–Giles, Bopomofo (Zhuyin), Gwoyeu Romatzyh, etc., and Romanization of Chinese. The following table shows the consonant sounds of Standard Chinese, transcribed using the International Phonetic Alphabet. The sounds shown in parentheses are sometimes not analyzed as separate phonemes; for more on these, see below. Excluding these, and excluding the glides j, ɥ, and w (for which see below), there are 19 consonant phonemes in the inventory. Between pairs of stops or affricates having the same place of articulation and manner of articulation, the primary distinction is not voiced vs. voiceless (as in French or Russian), but unaspirated vs. aspirated (as in Scottish Gaelic or Icelandic). The unaspirated stops and affricates may however become voiced in weak syllables (see below). Such pairs are represented in the pinyin system mostly using letters which in Romance languages generally denote voiceless/voiced pairs (for example [p] and [b]), or in Germanic languages often denotes fortis/lenis pairs (for example initial aspirated voiceless/unaspirated voiced pairs such as [ph] and [b]).
