This ebook covers all the sounds used in standard English, using Simplified Standard Sound Symbols (S4) to present them. Four audio clip examples are given for each sound.
S4 is a cut-down version of the International Phonetic Alphabet (IPA). Its target is Pan-English, with the ability to accommodate both standard British and standard American pronunciation.
Using standard pronunciation is like using standard spelling: if you don't use it you won't be understood.
Every student of English as a foreign language needs to master the 47 sounds listed here.
This version is for Mandarin Chinese speakers.
