Finicky Phonetics Part 2: Vowels
Unlike consonants, all Vowels exist in a continuous space unsurprisingly called the ‘vowel space.’ Vowels are distinguished mainly by their height and backness, referring to the position your tongue is in when you pronounce them. This can be visualized on the chart below, where right to left on the chart correlates to their pronounciation from the back of the mouth to the front.
