Until you learn the correct English slow down your speech.
It is more important that everything you say is understood.
Use your dictionary. Make a list of frequently used words that are difficult for you to pronounce.
Record yourself reading some sections of a book.
Pronounce the endings of each word. Pay special stress to “s” and “ed” endings.
Read aloud in English 15-20 minutes everyday.
Speak with more energy and enthusiasm.
Change your body language
Be Patient-You can change the way you speak but it won’t happen overnight!
