Implements modular TTS synthesis through dynamic library loading of language-specific algorithms (concatenative, HMM-based), with SSML documents automatically converted to internal data structures via CSSMLTraversal for transparent processing across pipeline stages. Cross-platform support enables swapping entire engines via XML configuration files, allowing researchers to compare different synthesis approaches (e.g., Putonghua concatenative vs. HMM) without reimplementing core orchestration logic.
