⚠️ Areas for Improvement

Due to its specialization, Voxygen has a few trade-offs:

💵 Investment Required – Custom voice creation and enterprise-grade deployment are significant investments, making it unsuitable for individuals or small projects.
💻 Public Accessibility – Not a consumer-facing tool; the interface and access are designed for corporate integrators and developers, not casual users.
🧠 Focus – The feature set is tailored for functional communication (IVR, navigation) rather than creative dialogue (gaming/animation).

🚀 How to Use Voxygen (Custom Voice Creation Process Example)
