43 * The %ISpeechToTextEventListener interface is a listener interface for speech recognition events.
44 * It provides methods that are invoked by the voice engine when the status is changed, an
45 * error or warning occurs or the result is received in the Speech-To-Text service. @n
46 * For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/uix/speech_to_text.htm">Speech-To-Text</a>.
