Answer:
Onomatopoeia.
Step-by-step explanation:
Onomatopoeia is the formation of words according to the sounds that they make. It phonetically imitates, resembles, and even makes words out of the very sounds that are produced. Such word structures enable a person to easily verify and understand what a given word is supposed to mean.
Examples of such words are hiss, buzz, slam, bash, bam, ufff, aarrghh, etc. These words are formed according to the sounds they make when they act. Likewise, the words used in the given sentence like "cheeped" "chirped" etc are onomatopoeic in nature.
