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]).

Gwoyeu Romatzyh (), abbreviated GR, is a system for writing Mandarin Chinese in the Latin alphabet. The system was conceived by Yuen Ren Chao and developed by a group of linguists including Chao and Lin Yutang from 1925 to 1926. Chao himself later published influential works in linguistics using GR. In addition a small number of other textbooks and dictionaries in GR were published in Hong Kong and overseas from 1942 to 2000. GR is the better known of the two romanization systems which indicate the four tones of Mandarin by varying the spelling of syllables ("tonal spelling").
A checked tone, commonly known by the Chinese calque entering tone, is one of the four syllable types in the phonology of Middle Chinese. Although usually translated as "tone", a checked tone is not a tone in the phonetic sense but rather a syllable that ends in a stop consonant or a glottal stop. Separating the checked tone allows -p, -t, and -k to be treated as allophones of -m, -n, and -ng, respectively, since they are in complementary distribution. Stops appear only in the checked tone, and nasals appear only in the other tones.
A homophone (ˈhɒməfoʊn,_ˈhoʊmə-) is a word that is pronounced the same (to varying extent) as another word but differs in meaning. A homophone may also differ in spelling. The two words may be spelled the same, for example rose (flower) and rose (past tense of "rise"), or spelled differently, as in rain, reign, and rein. The term homophone may also apply to units longer or shorter than words, for example a phrase, letter, or groups of letters which are pronounced the same as another phrase, letter, or group of letters.
Recently, several multi-layer perceptron (MLP)- based front-ends have been developed and used for Mandarin speech recognition, often showing significant complementary properties to conventional spectral features. Although widely used in multiple Mandarin s ...
Current HMM-based low bit rate speech coding systems work with phonetic vocoders. Pitch contour coding (on frame or phoneme level) is usually fairly orthogonal to other speech coding parameters. We make an assumption in our work that the speech signal cont ...

Prosody plays an important role in both identification and synthesis of emotionalized speech. Prosodic features like pitch are usually estimated and altered at a segmental level based on short windows of speech (where the signal is expected to be quasi-sta ...
