Lightning v2 WebSocket

The Lightning v2 WebSocket API provides real-time text-to-speech streaming capabilities with high-quality voice synthesis. This API uses WebSocket to deliver audio chunks as they're generated, enabling low-latency audio playback without waiting for the entire audio file to process. Perfect for interactive applications, voice assistants, and real-time communication systems that require immediate audio feedback.
