Re: What should I improve on, regarding my pronunciation? I really want to sound bett
I'm not an expert, either, but I'll share a few comments.
1. Your diction is very clear. I had no trouble understanding anything you said.
2. You have an accent. Don't worry about that! We all do. There's nothing wrong with sounding like you came from where you came from. Even among native speakers, our accents identify our nations, our regions, our ethnicity, our class, and sometimes even the city we come from. We all communicate with more than just words. You don't have to hide who you are.
3. Use every opportunity you can find to spend time with native English speakers. Watch English language movies. Listen to English language songs. Read English language magazines and newspapers. It will build your vocabulary and teach you the fine points of grammar and usage. Can you find or organize a Zoom group with native English speakers?
4. Most important: Give yourself time! It's a difficult language. You've obviously come a long way, and it can only get better. Your progress won't show daily or weekly, but year by year you'll become more fluent.
You're doing well. Keep up the good work!
