1. Counting numbers: eg. Thirty and thirteen! Wrong pronunciation on TY and TEEN!
The correct pronunciation of thirty - Mandy, Andy, Daddy, Dirty >>>Thirty!
The correct pronunciation of thirteen- Been, Teenager, between, Teen >>> Thirteen!
2. Confusion pronunciation on Beach and Bitch! Wrong pronunciation in EA and I!
The correct pronunciation of Beach - Dear, Pea, Flea, Tea >>> Beach!
The correct pronunciation of Bitch - Bit, Tip, Dig, Dick >>> Bitch!
Hopefully it helps
