Pinyin
Below you will find the 21 intials and 39 finals in Standard Chinese.
Initials
In red are aspirated sounds. That means they are pronounced with puff of air or with much friction. Listen once before attempting to repeat.
Since it is quite impossible to vocalize the initials by themselves, the finals o(uo), e and i have been added to the following 4 groups of initials to facilitate pronunciation.
