What are the three main features that linguists use to describe and distinguish between different vowel sounds?

The three main features are: how high or low the tongue is (tongue height), whether the tongue is front or back (tongue frontness/backness), and whether the lips are rounded or unrounded (lip rounding).

Describe the difference between the vowel sound [i] (as in 'see') and the vowel sound [u] (as in 'flute') using the three main features of vowel description.

The vowel [i] is a high front unrounded vowel, meaning the tongue is high and forward in the mouth, and the lips are not rounded. The vowel [u] is a high back rounded vowel, meaning the tongue is high and backward in the mouth, and the lips are rounded.

What is a diphthong? How are diphthongs represented using IPA symbols?

A diphthong is when two vowel sounds are said together within the same syllable, where the tongue starts in the position for one vowel and moves smoothly to the position for another vowel. In IPA, diphthongs are represented by combining the two individual vowel symbols in a row (e.g., [oi], [aɪ], [aʊ]).

1
Unlike consonants, vowels are made without closing the vocal tract, allowing us to sing them with our mouths open.
2
In the IPA, vowels are described by three main features: how high or low the tongue is, how front or back the tongue is, and whether the lips are rounded.
3
A diphthong is a sound made by combining two vowel symbols, indicating a movement from one vowel position to another, while schwa ([ə]) is the most common vowel sound in English, found in unstressed syllables.
