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

Definição

Obtém e define o evento da plataforma de fala que uma instância de SpeechEventInfo é usada para solicitar.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 da propriedade

Retorna um membro de TtsEventId como um short, indicando o tipo de evento SpeechEventInfo que o objeto deve gerar.Returns a member of TtsEventId as a short, indicating the event type the SpeechEventInfo object is to generate.

Exemplos

O exemplo a seguir faz parte de uma implementação de síntese de fala personalizada TtsEngineSsmlque herda de e usando o TextFragmentuso SpeechEventInfode FragmentState,, eTtsEventIdThe example below is part of a custom speech synthesis implementation inheriting from TtsEngineSsml, and using the use of TextFragment, SpeechEventInfo, FragmentState, and TtsEventId

A implementação deSpeakThe implementation of Speak

  1. Recebe uma matriz de TextFragment instâncias e cria uma nova matriz de TextFragment instâncias a ser passada para o Speak método em um mecanismo de síntese subjacente.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. Se o TtsEngineAction valor de enumeração encontrado Action na propriedade State no FragmentState retornado pela propriedade de cada TextFragment instância for Speak, a implementaçãoIf 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

    • Traduz o American Britishisms no texto a ser falado.Translates Americanism to Britishisms in the text to be spoken.

    • Se a EventInterest ITtsEngineSite Propriedade nas interfaces fornecidas para a implementação oferecer suporte ao WordBoundary tipo de evento, SpeechEventInfo uma instância será usada para criar um evento para gerar um medidor de progresso do sintetizador criado.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.

      Os parâmetros on SpeechEventInfo, incluindo EventId são usados para registrar o evento gerado por meio LogSpeechEvent do método.The parameters on SpeechEventInfo, including EventId are used to log the event generated through the LogSpeechEvent method.

  3. Um mecanismo de renderização de fala é chamado com a TextFragment matriz modificada.A speech rendering engine is then called with the modified TextFragment array.
