SpeechEventInfo.EventId SpeechEventInfo.EventId SpeechEventInfo.EventId SpeechEventInfo.EventId Property

Definición

Obtiene y establece el evento de la plataforma de voz que usa una instancia de SpeechEventInfo para realizar solicitudes.Gets and set the Speech platform event which an instance of SpeechEventInfo is used to request.

public:
 property short EventId { short get(); };
public short EventId { get; }
member this.EventId : int16
Public ReadOnly Property EventId As Short

Valor de propiedad

Devuelve un miembro de TtsEventId como short, que indica el tipo de evento que el objeto SpeechEventInfo va a generar.Returns a member of TtsEventId as a short, indicating the event type the SpeechEventInfo object is to generate.

Ejemplos

El ejemplo siguiente forma parte de una implementación de síntesis de voz personalizada que TtsEngineSsmlhereda de y usa el uso TextFragmentde SpeechEventInfo, FragmentState, yTtsEventIdThe example below is part of a custom speech synthesis implementation inheriting from TtsEngineSsml, and using the use of TextFragment, SpeechEventInfo, FragmentState, and TtsEventId

La implementación deSpeakThe implementation of Speak

  1. Recibe una matriz de TextFragment instancias de y crea una nueva matriz TextFragment de instancias de Speak que se van a pasar al método en un motor de síntesis subyacente.Receives an array of TextFragment instances and creates a new array of TextFragment instances to be passed to the Speak method on an underlying synthesis engine.

  2. Si el TtsEngineAction valor de enumeración que se Action encuentra en la FragmentState propiedad en la State devuelta por TextFragment la propiedad Speakde cada instancia es, la implementaciónIf the TtsEngineAction enumeration value by found from the Action property on the FragmentState returned by the State property of each TextFragment instance is Speak, the implementation

    • Traduce el Americanism a Britishisms en el texto que se va a hablar.Translates Americanism to Britishisms in the text to be spoken.

    • Si la EventInterest propiedad de las ITtsEngineSite interfaces proporcionadas a la implementación admite WordBoundary el tipo de evento SpeechEventInfo , se usa una instancia de para crear un evento para impulsar la creación de un indicador de progreso de sintetizador.If the EventInterest property on the ITtsEngineSite interfaces provided to the implementation support the WordBoundary event type, a SpeechEventInfo instance is used to create an event to drive a synthesizer progress meter is created.

      Los parámetros de SpeechEventInfo, incluidos EventId , se usan para registrar el evento generado a LogSpeechEvent través del método.The parameters on SpeechEventInfo, including EventId are used to log the event generated through the LogSpeechEvent method.

  3. A continuación, se llama a un motor de representación de TextFragment voz con la matriz modificada.A speech rendering engine is then called with the modified TextFragment array.
