+# YomiTalk サンプルテキスト
+
+このテキストファイルは、YomiTalkのテキストファイル読み込み機能をテストするためのサンプルです。
+
+## 機能概要
+
+YomiTalkは以下の機能を備えています:
+
+1. PDFファイルからのテキスト抽出
+2. テキストファイル（.txt, .md）からの読み込み
+3. OpenAI APIを使用した会話形式テキスト生成
+4. VOICEVOX Coreを使用した音声合成
+
+このサンプルテキストが正常に読み込まれると、上記のテキストが抽出され、トークが生成されます。
+その後、音声合成がされるとずんだもんと四国めたんの声でポッドキャスト音声が作成されます。
+
+テストが正常に完了することを願っています！
