**Install dependencies**\n   ```bash\n   npm install\n   ```\n\n3. **Set up environment variables**  \n   Create a `.env.local` file and add:\n   ```bash\n   # Stack Auth (for authentication)\n   NEXT_PUBLIC_STACK_PROJECT_ID=your_stack_project_id\n   NEXT_PUBLIC_STACK_PUBLISHABLE_CLIENT_KEY=your_stack_publishable_client_key\n   STACK_SECRET_SERVER_KEY=your_stack_secret_server_key\n\n   # Firebase (Auth + Firestore + Database)\n   NEXT_PUBLIC_FIREBASE_API_KEY=your_firebase_key\n   NEXT_PUBLIC_FIREBASE_AUTH_DOMAIN=your_auth_domain\n   NEXT_PUBLIC_FIREBASE_PROJECT_ID=your_project_id\n   NEXT_PUBLIC_FIREBASE_STORAGE_BUCKET=your_bucket\n   NEXT_PUBLIC_FIREBASE_MESSAGING_SENDER_ID=your_sender_id\n   NEXT_PUBLIC_FIREBASE_APP_ID=your_app_id\n   NEXT_PUBLIC_FIREBASE_MEASUREMENT_ID=your_measurement_id\n\n   # Speech Processing\n   NEXT_PUBLIC_DEEPGRAM_API_KEY=your_deepgram_key\n   DEEPGRAM_API_KEY=your_deepgram_key\n\n   # AI / NLP\n   NEXT_PUBLIC_OPENAI_ROUTER_KEY=your_openrouter_key\n   NEXT_PUBLIC_GEMINI_API_KEY=your_gemini_key\n   NEXT_PUBLIC_GEMINI_MODEL=gemini-1.5-pro\n   ```\n\n4. **Run the development server**\n   ```bash\n   npm run dev\n   ```\n\n5. **Open in browser**\n   ```\n   http://localhost:3000\n   ```\n\n---\n\n## 🧠 How It Works\n\n1. User selects a mode (Interview / English Practice / Topic Practice).\n2. App connects with AI backend (Gemini API via OpenRouter).\n3. Voice input processed via Deepgram STT → AI generates response → Speech output via TTS.\n4. Full conversation + feedback stored in Firebase.\n5. User can revisit and analyze past sessions anytime.\n\n---\n\n## 📄 License\n\nThis project is open-source and available under the [MIT License](LICENSE).\n\n---\n\n## 🤝 Contributing\n\nPull requests are welcome!  \nFor major changes, please open an issue first to discuss what you’d like to change.\n\n---\n\n## 👤 Author\n\n**Dev Kushwah**  \n📧 [devkushwah880@gmail.com](mailto:devkushwah880@gmail.com)\n\n---\n\n⭐ If you like this project, don’t forget to **star** the repo!\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdevkushwah%2Fmock-interview-preparation-sytem","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdevkushwah%2Fmock-interview-preparation-sytem","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdevkushwah%2Fmock-interview-preparation-sytem/lists"}
