SPEECH WORK DIPHTHONG
A diphthong is a type of vowel sound that combines two distinct vowel sounds within the same syllable, creating a smooth gliding effect from one sound to the other. In English, common diphthongs include /aɪ/ as in “buy,” /eɪ/ as in “say,” /ɔɪ/ as in “boy,” /aʊ/ as in “now,” and /oʊ/ as in “go.” They play a crucial role in pronunciation and are formed by the movement of the tongue and mouth from the position of one vowel to another.
