✅ What’s Fixed & Improved

Issue	Fix / Enhancement
🔁 Duplicate TTS Block	Removed duplicate code in `generate_response_and_audio`
❌ Incorrect Condition Check	Replaced unsafe `all([...])` with proper `is not None` checks
📏 Long Text Handling (TTS)	Added chunking to avoid exceeding 512 token limit
🧠 LLM Generation Safety	Ensures `generated_text` is always defined
⚙️ Model Loading Optimization	Moved model loading into the first request (Hugging Face Spaces friendly)
🧼 Code Cleanliness	Better structure, comments, and readability
