How to learn English pronunciation;
Looking for a study partner:
It is very important to get feedback from others. Find a friend who is interested in improving English. Try changing the recording material so that you can hear the pronunciation of the other party. Remember to listen again after recording and find out the mistakes and key points.
Read aloud:
Good pronunciation is more than just mastering a single syllable. Or the understanding of intonation (rising and falling tone) and stress (some syllables in words and some words in sentences are pronounced louder and clearer). Read some poems, speeches and songs aloud, and concentrate on practicing the stress and tone of words.
When learning phonetic symbols, you should have experienced instructors to guide you. If the conditions do not allow, find a video with standard pronunciation and practice with the mouth shape of the people in the video. You should have a mirror when practicing. I just started practicing phonetic symbols, and I need to use a mirror to make my mouth shape up to standard.
Pay attention to long sounds and short sounds when learning phonetic symbols. Long sounds should be pronounced completely, and short sounds should be short and light. After practicing the long and short sounds of a phonetic symbol, you should compare and practice repeatedly, and then you can continue until you practice the long and short sounds of this phonetic symbol with ease. After practicing phonetic symbols, you can improve the endurance of mouth muscles and lips by practicing phrases.
