If you know those, could you please help me?
And are there special way to get it more easy?
I'd like to try those.
The schwa is a completely neutral sound in English - like a little grunt. I use a couple of drill methods in class so the students can get the right sound. There are a number of youtube videos which demonstrate it, so have a look and see what you can work out.
The flap - usually for D/T and very rarely for R - exists in a couple of English accents, but it's not the most important part of pronunciation. Still, it's something you can practise once you know when you can use it. In my regional accent, it doesn't exist at all... even in educated accents.
Thank you so much!
Your correct explanations are really helpful to understand to practice it!
By the way, I think I might do not eat butter, beacuse of flap. lol
Flap 't' at the end of words sounds like 'd' in the american english.
