Refactor api_v2.py and api_v3.py to update sampling parameters and weight paths for better clarity and support for v3/v4 vocoders. Introduce new methods in PrepareCoordinator for handling empty text features and improve profiling capabilities. Additionally, update unified engine components to streamline audio processing and state management, enhancing overall performance and maintainability of the TTS system.
Introduce new modules including unified_engine_component_models, unified_engine_component_policy, unified_engine_component_registry, unified_engine_component_runtime, unified_engine_worker_completion, and unified_engine_worker_decode. These additions enhance the TTS framework by providing structured models for request handling, engine policies, and worker execution, significantly improving the architecture and maintainability of the system. The new components support asynchronous operations and optimize overall performance through better state management and processing capabilities.
