短语识别系统负责管理短语识别器和向它们分发识别事件。
为了使任何短语识别器都能够识别短语,PhraseRecognitionSystem 必须在运行中。启动短语识别将自动启动短语识别系统(如果它此前已停止运行)。
如果没有活动的听写识别器,短语识别系统就无法启动。
短语识别系统目前仅在 Windows 10 上可用。使用 PhraseRecognitionSystem.isSupported 属性确定运行应用程序的系统是否支持语音识别。
isSupported | 返回运行应用程序的设备是否支持语音识别。 |
Status | 返回短语识别系统的当前状态。 |
OnError | 当短语识别系统发生错误时触发的事件。 |
OnStatusChanged | 当短语识别系统的状态更改时发生的事件。 |
ErrorDelegate | OnError 事件的委托。 |
StatusDelegate | OnStatusChanged 事件的委托。 |
