What is 'phonetics'?


音声学(phonetics): /fəˈnɛtɪks/

cf. 音韻論(phonology): /fəˈnɒlədʒi/, /fəˈnɑlədʒi/

  • 個別言語ごとの言語音の機能的構造(体系)や音韻規則などが研究対象

ちなみに

フォニックス(phonics): /ˈfɒnɪks/, /ˈfɑnɪks/

  • 英語の発音と綴りの規則を習得するための学習/教育法
  • 音声学や音韻論の知見を基礎としている
  • 歴史的経緯により、英語は正書法(orthography)がかなり不規則
    • → 英語圏で読み書きを学び始める際に取り組むことのひとつ

cf. Phonics - Oxford Owl for Home


Why phonetics matters?


  • 自然言語を使う際に発音や文法を気にしすぎる必要はないが……
  • 音声学の知識があると
    • どのように言語音を作るのかが分かる
    • 母語や外国語の発音を矯正できる
      • 発音できるものは聴き取れる → listening/speakingが効率化
      • 語彙/文法を覚えやすくなる → reading/writingが効率化
    • 語学学習の効率が高まる

Let's learn the basics of phonetics!
