When learning Chinese Pinyin, you shall be aware of certain limitations:
- Pinyin does not represent English pronunciation and should not be pronounced according to English conventions. You are advised to learn Pinyin phonetic conventions, bearing in mind that many sounds have no equivalents in Englishss.
- Since Pinyin is based only on the sounds of Mandarin Chinese, Pinyin is unsuitable for use for speakers of some other Chinese spoken dialects, because the sounds do not correspond to their speech.
- The phonotactics of spoken Mandarin Chinese dictate a relatively small set of possible syllables and there is a potential for homonyms. Because of this, Pinyin can be ambiguous, especially when transcribing Standard Written Chinese, which uses formal constructions not often found in speech. However, this should not be an issue in the transcription of normal spoken Mandarin conversation since speakers would not use such ambiguous constructions in speech.
