ShadowMark は、英語シャドーイングのための教材づくりから、音声変化の可視化、録音した発音の比較分析までを1つで行える学習アプリです。すべて端末内で完結し、アカウント登録は不要です。 ■ 音声変化を「見える」教材に 英文を取り込み、リンキング、弱形、消失、同化、フラップ、ダークL、メモなどをテキスト上に直接アノテーションできます。本文を後から編集してもアノテーションは保たれます。 ■ 教材音源から音声変化を自動検出 教材の音声を解析し、フラップやリンキングなどの候補を自動検出。本文に重ねてプレビューし、該当箇所の音声を聞きながら1件ずつ承認・棄却して、納得したものだけを反映できます。 ■ 録音を教材と比較して、直すべき点が分かる 自分のシャドーイングを録音すると、教材音源と比較してリズム・抑揚・速さ・ポーズ・単語の正確さをスコア化し、具体的な改善アドバイスを表示します。 ・音量と声の高さの推移グラフ:教材のタイミングに合わせた補正表示で山と谷を直接比較。タップすればその位置から再生でき、単語の目盛りでどの語かも分かります ・メルスペクトログラムの見比べ ・アノテーション箇所ごとの発音チェック:フラップが弾けているかなどを判定し、教材と自分の録音を区間ごとに聞き比べられます ■ 練習を支えるプレーヤー 再生速度 0.1〜2.0倍(ピッチ維持)、A-Bループによる区間リピート、5秒戻し/5秒送り、教材を再生しながらの録音モードを備えています。 ■ 続けるほど上達が見える 連続練習日数、録音回数、テイクごとのスコア推移をグラフで確認できます。 ■ プライバシー 教材、音声、録音、アノテーション、分析結果はすべて端末内に保存されます。音声認識・音声分析も端末内で実行され、音声が外部に送信されることはありません。アノテーション済みテキストは画像またはPDFとして書き出せます。
