+
+Welcome to the **TTS Dataset Recorder**! This tool helps you quickly create a high-quality dataset for Text-to-Speech (TTS) models. Whether you're starting from scratch or have a pre-existing set of text data, this app lets you record audio samples and export them with the corresponding metadata.
+
+### **How to Use?**
+1. **Upload a JSON File** containing the sentences you'd like to record (or manually input them through the app).
+2. **Record Audio** for each sentence. The app will automatically associate your recordings with the correct text.
+3. **Export the Dataset** as a JSON file or **Sync** to HuggingFace for easy sharing and use.
+
+### **Data Input Format**
+Your JSON file should follow this structure:
+```json
+[
+    { "id": "001", "text": "Hello, how are you?" },
+    { "id": "002", "text": "This is a sample sentence." }
+]
+
+                """)
