• Antonym沈黙ちんもくNeutralSaying nothing and keeping silent, or an absence of sound. It is the opposite of 「ペラペラ」 only in its sense of talking on and on.
• Antonym無口むくちNeutralDescribes a person who is taciturn by nature and speaks little. It contrasts with 「ペラペラ」 only in its talkative sense, not the fluent-foreign-language one.
• AntonymしじまWrittenRead 「しじま」. A word of written, formal prose for deep stillness, also for keeping silent; it opposes the chattering 「ペラペラ」 in whether sound is present.

Use 「ペラペラ」 for fluent foreign languages or nonstop talk, as in 「英語がペラペラ」; it also describes thin, floppy paper or cloth. 「薄い」 is the plain word for thin; 「薄っぺら」 adds a flimsy, cheap feel. For a person of few words, use 「無口」; 「沈黙」 and 「静寂」 are its opposites.
