DictationRecognizer.Start

public void Start();

Description 描述

Starts the dictation recognization session. Dictation recognizer can only be started if PhraseRecognitionSystem is not running.

DictationRecognizer requires that dictation is permitted in the user's Speech privacy policy (Settings->Privacy->Speech, inking & typing). If dictation is not enabled, DictationRecognizer will fail on Start. Developers can handle this failure in an app-specific way by providing a DictationError delegate and testing for SPERR_SPEECH_PRIVACY_POLICY_NOT_ACCEPTED (0x80045509).
