ぺらぺら is casual and often implies native-like fluency, while 流暢に is more formal and can be used in writing or polite speech. ぺらぺら is commonly used in self-introductions or informal settings, whereas 流暢に is preferred in resumes or formal descriptions.
English 'fluently' is often used with 'speak', but in Japanese, the adverb must match the verb. Do not directly translate 'I am fluent' as 私は流暢です; instead use 流暢に話せます or ぺらぺらです.
