class TtsManager
Defined at line 23 of file ../../src/ui/a11y/lib/tts/tts_manager.h
A class to intermediate interaction between speakers and Tts Engines.
The Tts manager implements |fuchsia.accessibility.tts.TtsManager| and
|fuchsia.accessibility.tts.EngineRegistry| interfaces. It it registers a
speaker (assistive technology wanting to produce speech output), as well as a
Tts engine which is capable of producing the speech output.
The speaker, after registration, calls methods defined by |fuchsia.accessibility.tts.Engine|,
which are then forwarded to the registered Tts Engine.
