Hello. You did not enter the text to which this question refers, which prevents you from being able to tell you which sound resource was used. However, I will tell you about the possible sound features and how to identify them. I hope it helps.
Alliteration: Occurs with the repetition of consonants on the same line. The goal is to create very similar or equal sounds at the beginning or in the middle of the words. Ex: Peter Piper picked a peck of pickled peppers.
Assonance: Promotes the repetition of vowels, mainly in atomic syllables. The intention is to generate similar sounds through the vowels, creating a pleasant sound rhythm. Ex: "Fleet feet sweep by sleeping geese"
Onomatopoeia: Promotes the representation of sounds through words. Ex: Silence your cellphone so that it does not beep during the movie.
Rhyme: Promotes the repetition of the same syllable, or the same sound, at the end of each sentence. Ex: "Eyes on the prize, they always make me fly.
