Giving examples, explain the concept of pure vowels, diphthongs, and triphthongs.

Pure vowels are vowel sounds that are produced without any change in quality throughout their duration. Examples of pure vowels include the sounds /i/ as in "beet," /ɑ/ as in "father," and /u/ as in "boot."

Diphthongs are vowel sounds that consist of a combination of two vowel sounds within the same syllable. The sound starts at one vowel and glides into another vowel sound. Examples of diphthongs include /aɪ/ as in "ride," /eɪ/ as in "day," and /oʊ/ as in "go."

Triphthongs are vowel sounds that consist of a combination of three vowel sounds within the same syllable. The sound starts at one vowel, glides into a second vowel, and then glides into a third vowel sound. Examples of triphthongs include /aʊə/ as in "hour," /aɪə/ as in "fire," and /jʊə/ as in "cure."

Pure Vowels

- Pure vowels are single sounds that are not combined with any other sounds.
- Examples: /a/ as in "cat," /i/ as in "sit," /u/ as in "foot"

Diphthongs

- Diphthongs are combinations of two vowel sounds that are produced as a single syllable.
- The first vowel sound is strong and the second vowel sound is weak.
- Examples:
- /ai/ as in "bite" (/bʌɪt/)
- /ei/ as in "bay" (/beɪ/)
- /ɔi/ as in "boy" (/bɔɪ/)

Triphthongs

- Triphthongs are combinations of three vowel sounds that are produced as a single syllable.
- The first vowel sound is strong, the second vowel sound is weak, and the third vowel sound is very weak.
- Examples:
- /aɪə/ as in "fire" (/faɪər/)
- /aʊə/ as in "hour" (/aʊər/)
- /ɔɪə/ as in "tire" (/tɔɪər/)
