# 説明

- このアプリは、ゲームのセリフを感情ラベル付けして、大規模な感情音声データセットを作成するためのものです
- **性的な音声が含まれるため、18歳未満の方はご利用をお控えください**
- 既存のラベルが適切であれば、そのまま「現在の感情ラベルで適切」ボタンを押してください
- ラベルを修正する場合は、適切なボタンを押してください
- ショートカットキー（カッコ内）を使うこともできます

# 補足

- `🥰 NSFW1` は女性の性的行為中の音声（喘ぎ声等）
- `🍭 NSFW2` はキスシーンでのリップ音やフェラシーンでのしゃぶる音（チュパ音）を表します
- 感情が音声からは特に読み取れない場合は `😐 中立` を選択してください
