Teacher Aurelia goes through two sounds that are very difficult to differentiate between for the majority of Spanish speakers; the long and short ee sound.
The short sound doesn’t exist in Spanish and many words sound the same but are actually different; for example “sit”and “seat”. This can lead to social faux pas because many people say “bitch”and “beach”in the same way!
Small improvements in our pronunciation is what makes the difference between sounding like a native English speaker and someone who struggles to communicate well.
