Let’s begin to work on vowel sounds in pairs. One of my mistakes was that I couldn’t differentiate between two vowels: the long E vowel (like in sheep) and short I vowel (like in ship). Understanding the difference between these two vowels is very important, otherwise you can misunderstand others, or you can be misunderstood and get into an awkward situation. For example, if you say shit instead of sheet during a presentation, or bitch instead of beach, or piss instead of peace, you may seem offensive, vulgar or very rude. You have to be careful. In this article, I will mention Rachel’s English (including her video channel) and Mandy’s pronuncian.com podcast.
