My old teacher found I like inserting schwa after consonants. When I was pronouncing and, I said it like /əndə/. She asked me to drop the last d to avoid the epenthesis.
Now I'm learning the word dwell and dwelling. I know I have the habit of insertion but I'm not sure if I'm doing it in the word dwell. I feel I'm pronouncing /dwel/ and /dəwel/ the same.
I watched many Youtube videos teaching consonant /d/, including Sounds American but none of them mentions how to tackle /də/. I don't see distinctions between the second phase of /d/ and /ə/.
Can anyone articulate the pronunciation differences between /d/ vs /də/ ? Describing in text may be difficult, links to other resources are appreciated.
