DELETION
Deletion commonly occurs in spoken language. Deletion is the omitting of certain sound of words when one is speaking in normal speed. Deletion may occur to either vowels or consonants. However, not all vowels and consonants may be deleted.
Consonants deleted in normal speech are /h/, /t/, /d/, and /k/. Consonant /h/ is deleted from functional words; whereas /t/, /d/, and /k/ from those which contain consonant clusters.
Vowels deleted in connected speech are those of schwa sound or weak sound, unstressed syllables, and functional words.
