Phonetic devices are those which make use of the combinations and repetition of sounds, and of different patterns of rhythm. The most important devices are:
Alliteration: The multiple, close repetition of the same sound, aiming to imitate a given sound or to give a certain sensation. “That silly scent Willy sent Millicent.” The repetition of the sound “s” makes the reader think of the sound made by perfume being pulverized from a bottle.
Paronomasia: A play on words or a pun in which homophone words are used, although their meaning is different. “They delivered summer dresses to some addresses.“
Rhyme: Endings that sound similarly for different phrases, sentences or lines. “Pretty women wonder where my secret lies. / I'm not cute or built to suit a fashion model's size.” In this case, both lines end with the same sounds, /īz/, so the word “lies” rhymes with “size”.
