Abstrak:Pronounciation is the important part to be learnt by L2 learners especially by Indonesian students who learn English. It is because different pronounciation conveys diferent meaning. For example the word bed should be pronounced as /bed/ not /bet/ since the letter sound represents the different word namely bet in which it has different meaning from the word bed. However, mostly Indonesian learners tends to pronounce two words stated before ; bed and bet in the same way. So they can not distiguish /d/ and /t/ sound at the final word position. Consequently, there might be misunderstanding in oral communication process due to that mistake. Due to that fact, the Indonesian students should be taught how to prounounce English sounds correctly. One way to teach pronunciation is by using You Tube?s audio-video.You Tube?s audio-video provides the English native speaker who pronounces the English sound correctly.

Lastly, she/he explains how to pronounce the English sound to the students. Hopefully by the end of the course, the students are able to able to pronounce the English sound correctly. At last, it can be concluded that using You Tube?s audio-video is a new way in which it should be tried by a teacher of pronounciation. Keywords : pronounciation, You Tube, pronounciation mistake
