📝 About this app
Hey guys! バイリンガールのちかです！
私はYouTubeで「バイリンガール英会話」というチャンネルを通して楽しく英語に触れられる動画を配信しています。
海外旅行で英語で話す時って「なんて言えばよいのか？」「発音合ってるかな…」など、ドキドキしますよね。そんな時に、テキストと音声で英語のフレーズを確認できるのが、このアプリ。
空港やホテル、レストランなど11つのシチュエーションごとに分類して、1000個以上の英会話フレーズを紹介しています！音声は、私・吉田ちかのの声で収録しているので、YouTubeで馴染みのある声で聴くことができてちょっと安心？！
音声は3段階のスピードで聴くことができます。ちなみに、機械的に3段階にしているのではなく、私が「Slow」「Normal」「Fast」をそれぞれ実際に言って録音しています。
音声はオフラインでも聴くことができるので、Wi-Fiなどの環境がなくても大丈夫！海外に行って使いたいのにWi-Fiがないからいざという時に使えない！なんてことはありません。
さらに、シチュエーションごとによくある会話のセリフを動画で確認ができるようにしています。
リアルな会話が繰り広げられる「バイリンガール英会話」の動画もその場で視聴できるので、海外にいなくてもその雰囲気を味わいながら、フレーズを練習できます。… View full description on the official store →
