If you’re thinking about altering your accent, try focusing on these aspects of language:
- study the characteristics of your language’s sound system and how it differs from English. Start with the differing consonants, which seem to create more misunderstandings.
- practice in phrases (not individual words) and how one word blends with the words surrounding it
- move your mouth more than you’re used to – open it wider like you’re yawning, spread the corners of your lips to meet your ears! This sounds like an exaggeration, but moving your mouth in different ways is a major component of forming new sounds.
- watch Americans’ lips when they speak – watching on TV is OK to avoid any awkwardness, but the Simpsons, Family Guy, or some other cartoon won’t help you.
- listen to and imitate sentence stress and intonation and stress patterns within phrases (my favorite activity for this is listening to and singing along with music)
- copy what you hear exactly and often (as exact and as often as you can)
This is all I can think of for now, but there are more. I’ll post them as I start to remember them. For now, I hope these help.
