However, you can find some examples of assonance in the speech:
* "Let freedom ring from the profound mountains of New Hampshire." (Repetition of the "o" sound)
* "Let freedom ring from the sickly sounds of southern states." (Repetition of the "s" and "o" sounds, primarily in the "sounds" and "south" words)
* "I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character." (Repetition of the "ch" and "o" sounds)
While these are a few examples, it's important to remember that King's speech primarily relies on other poetic devices for its impact. The repeated use of "Let freedom ring" throughout the speech, for example, is more impactful through its repetition and parallel structure than through any particular sound device.
