Translation guide
In Japanese, mumbling is often expressed through onomatopoeia, specific verbs, or descriptive phrases. The most common way is the adverb ぶつぶつ, which mimics the sound of muttering. Other options include もごもご for indistinct speech, and verbs like つぶやく for murmuring. The choice depends on whether the mumbling is complaining, speaking unclearly, or talking to oneself.
