Bing Speech Service

• Go back to Azure Dashboard and click on your new Service
• The secret keys and your subscription id is necessary for your authentication. You have to copy & paste them to your config.properties

Bing Connector

• For Text to Speech and Speech to Text requests.

public class BingConnector implements MessageListener {

    private void generateAccesToken(){}

    private void sendSpeechToTextRequest(final BotMessage botMessage){}

    private void sendTextToSpeechRequest(final BotMessage botMessage){}
}

• AccessToken is required to successfully send parsing-request. Token generates from secret-keys mentioned above.
• AccessToken decays after 10 mins. You need to refresh the Token.

Important: Speech to Text REST requests need to have Transfer-Endcoding: chunked Header!
