When we learn a foreign language as English, we should learn to pronounce it correctly. I know that it is very hard for my students and for all the non-native English speakers. Incorrect pronunciation can be very embarassing because if you don't pronounce words and expressions correctly, nobody can understand you, so communication could fail, and pronunciation mistakes can lead to some serious misunderstanding.
Hints to get a correct pronunciation:
1. You should look it up in the dictionary to find the correct pronunciation
2. You can listen to English songs or watch your favourite films in English version, with subtitles in Italian or not.
3. Try to learn 10 words a day and practice them in front of a mirror.
But you first should watch the videos below and start to learn the Phonetic symbols and how to pronounce them.
