And as Daniel says... write the words down again and again. Repetition is very important. And say them OUT LOUD to yourself. Your EARS need to hear the words!

Vocabulary should be learnt in context. Repeat the word in whole sentences, or in common phrases. I always think you should play with a word (and vocabulary in general). Quizzes and crosswords and games are great for learning. Even for adults! Another technique is to think of the word and its 'family.' For example, the adjective 'happy' ... we also have the noun 'happiness,' the adverb 'happily,' and with a prefix... unhappily. For children, I rely on songs and nursery rhymes. They are great fun, and teach stress/intonation along with meaning. And usually they are easy to remember. Even if you are all grown up... I still think songs and rhymes are a good way to learn vocabulary... and perhaps to gain confidence! Learning a language is about gaining confidence too. And having fun! Try the British Council website for cartoon nursery rhymes and songs. Don't laugh! I'm serious. Even if you are 90 years old there is nothing wrong with a little karaoke! Sing along! If you have children.. teach them the songs too. Teaching someone else is a great way to learn! Here's a link to The British Council LearnEnglish website... and a simple vocabulary guessing game. I don't know how old you are, or your level... but you can navigate the website to find games that suit you. If you have children then click on LearnEnglish Kids ... and then SONGS for some really nice songs with worksheets for children (and their parents). It's easy for children to learn vocabulary while they sing! I hope this helps. Other teachers will have other ideas. Better ones, maybe! But there are no quick fixes. You need patience. http://learnenglish.britishcouncil.org/en/word-games/pic-your-wits

I think you are asking how to "remember" vocabulary words. Try writing them over and over again.

If you worried about the pronunciation then you can type the word in Google translate and click on the listen option.
