VocaMimic is a multilingual phrase trainer built on a simple idea: you learn to hear by learning to speak. Save the phrases that matter to you, practice them with your own voice, and turn passive knowledge into something you can actually use. Key Features ◆ Three Training Modes Listen: Hear the model voice, then repeat Read: See the phrase, then speak it aloud Speak: See only the meaning, then say it in your own words Step-by-step practice helps you build usable expressions naturally. ◆ Ear Check Quiz Take a 10-question listen-and-speak quiz using the phrases you've trained. Expressions you thought were easy may suddenly fall apart when they become sound. Challenging phrases are prioritized automatically, and you can review your daily progress on the calendar. ◆ Suggested Phrases (English) From a curated pool of 500 carefully selected phrases— including tricky pairs like "I can" and "I can't," or "wanna" and "want to"— you'll receive smart suggestions that sharpen your listening skills. ◆ Your Pronunciation, Heard Record your voice and play it back instantly. Compare it with the model and enjoy the feeling of getting closer, little by little. Get feedback on whether your pronunciation came through—right on the spot. ◆ Your Personal Phrase Collection A phrase for your next trip, lyrics from your favorite song, a memorable movie line. Save the words that move you and build your own treasure chest. ◆ Focus on the phrases you struggle with During training, phrases marked as OK are temporarily removed from the current practice. When you feel confident, you can mark phrases as learned to exclude them from future training. ◆ 14 Languages Supported Latin-based: English (3) · Spanish (3) · French (2) · German (3) · Italian · Portuguese Non-Latin: Korean Just 10 minutes a day, speaking out loud. The more you practice, the more the words become yours.

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。
