噼里啪啦 (pī lǐ pā lā) is a Chinese onomatopoeia that describes a sound of rapid, persistent or noisy action, such as a person talking quickly or a machine working rapidly. In Engpsh, this sound could be described as "chattering," "clattering," or "rattpng." For example:

The teacher's pen was making a 噼里啪啦 sound as she wrote on the whiteboard. (In this sentence, 噼里啪啦 could be translated as "rattpng.")

The students were making a 噼里啪啦 noise as they talked excitedly about the field trip. (In this sentence, 噼里啪啦 could be translated as "chattering.")

The old engine was making a 噼里啪啦 sound as it struggled to start. (In this sentence, 噼里啪啦 could be translated as "clattering.")
