Deberá crear una conversación a la que pueda unirse:

1. Inicie el explorador y vaya a https://translator.microsoft.com.
2. Seleccionar "Iniciar conversación".
3. Inicie sesión mediante cualquiera de las opciones disponibles.
4. Escriba un nombre (por ejemplo, El anfitrión).
5. Seleccione un idioma (por ejemplo, Español).
6. Seleccione el botón Entrar.
7. Anote el código de conversación de la parte superior de la página.

Vuelva a Visual Studio y reemplace la cadena YourConversationId por el identificador de conversación que creó en el paso anterior.

Cuando haya terminado de hablar, presione Ctrl+ C en el teclado para detener la captura de audio.

Copie y pegue la siguiente función en helloworld.cpp justo delante de la función int main():

void JoinExistingConversation(const std::string& conversationId)
{
    std::string speechLanguage("en-US");

    // You'll now need to create a ConversationTranslator to send audio, send IMs, and receive conversation events
    auto audioConfig = AudioConfig::FromDefaultMicrophoneInput();
    auto conversationTranslator = ConversationTranslator::FromConfig(audioConfig);

    // Attach event handlers here. For example:
    conversationTranslator->Transcribing += [](const ConversationTranslationEventArgs& args)
    {
        std::cout << "Received a partial transcription from " << args.Result->ParticipantId << ": " << args.Result->Text << std::endl;
        for (const auto& entry : args.Result->Translations)
        {
            std::cout << "\t" << entry.first << ": " << entry.second << std::endl;
        }
    };
    conversationTranslator->Transcribed += [](const ConversationTranslationEventArgs& args)
    {
        std::cout << "Received a transcription from " << args.Result->ParticipantId << ": " << args.Result->Text << std::endl;
        for (const auto& entry : args.Result->Translations)
        {
            std::cout << "\t" << entry.first << ": " << entry.second << std::endl;
        }
    };
    conversationTranslator->TextMessageReceived += [](const ConversationTranslationEventArgs& args)
    {
        std::cout << "Received an instant message from " << args.Result->ParticipantId << ": " << args.Result->Text << std::endl;
        for (const auto& entry : args.Result->Translations)
        {
            std::cout << "\t" << entry.first << ": " << entry.second << std::endl;
        }
    };

    // Join the conversation
    conversationTranslator->JoinConversationAsync(conversationId, "participant", speechLanguage).get();

    // Start sending audio
    conversationTranslator->StartTranscribingAsync().get();
    std::cout << "Started transcribing. Press Ctrl + C to stop" << std::endl;
    future.get(); // wait for Ctrl - C to be pressed

    // Stop audio capture
    conversationTranslator->StopTranscribingAsync().get();

    // Once you are done, leave the conversation
    conversationTranslator->LeaveConversationAsync().get();
}

Reemplace StartNewConversation(); en la función int main() por:

// Set this to the conversation you want to join
JoinExistingConversation("YourConversationId");

Deberá crear una conversación a la que pueda unirse:

1. Inicie el explorador y vaya a https://translator.microsoft.com.
2. Seleccionar "Iniciar conversación".
3. Inicie sesión mediante cualquiera de las opciones disponibles.
4. Escriba un nombre (por ejemplo, El anfitrión).
5. Seleccione un idioma (por ejemplo, Español).
6. Seleccione el botón Entrar.
7. Anote el código de conversación de la parte superior de la página.

Vuelva a Visual Studio y reemplace YourConversationId en la función int main() por el identificador de la conversación del paso anterior.

En la barra de menús, seleccione Compilar>Compilar solución para compilar la aplicación. El código se debería compilar sin errores ahora.

Elija Depurar>Iniciar depuración o presione F5 para iniciar la aplicación HelloWorld.

Cuando aparezca el mensaje Started transcribing, puede empezar a hablar. Verá que mientras habla aparecen las transcripciones.

• Si vuelve al explorador, verá que las transcripciones aparecen ahí mientras habla.

Cuando haya terminado de hablar, presione Ctrl+C para detener la captura de audio y finalizar la conversación.

Vuelva al explorador y salga de la conversación con el botón de salida situado en la esquina superior derecha.
