ISpTTSEngine
This interface defines the SAPI 5.0 text-to-speech (TTS) engine, a driver that is used for speech synthesis. SAPI calls this engine at its ISpTTSEngine::Speak method to render speech. SAPI itself performs the XML parsing of the input text stream.
Even though SAPI uses a free–threaded architecture, it always calls TTS engine objects on a single thread. SAPI ensures that parameter validation and thread synchronization have been performed properly before calling a TTS engine.
Applications never directly access TTS engines. All calls to an engine are made within a try-catch block to protect applications from faulting.
