Dialogflow
| Tip |
|---|
Before you start: make sure your MARBEL agent is connected to your Dialogflow agent and you completed the Getting Your Conversational Agent Up and Running step. |

Test that your greeting intent is working by using the microphone button in the test console on the Dialogflow console page. Try various phrases also using the test console and check whether what you say is recognized as a greeting intent. |
Prolog and Patterns
Greeting pattern without self-identification
...
To capture the example pattern, we will use the Prolog predicate pattern([PatternID | Sequence]). Note that this predicate only takes a single list argument, but this list should always have the same structure: the first item in the list should be a PatternID or name of the pattern, followed by a sequence of dialog moves or actor-intent pairs (more on this below).
...
We have used the same name or label greeting that we used for the user’s move and also for the agent’s move in the pattern that we defined. This makes sense conceptually because the moves are the same type of move, i.e. a greeting from one actor to another. The same intent label, however, should be handled very differently for the agent than for a user. Dialogflow should handle the natural language understanding (NLU) of a user’s move first by (transcribing the speech and then) classifying the m’s user move’s intent and making sure the agent generates natural language (NLG) text as output for a speech synthesizer. A user’s intent thus can be viewed as an input label whereas agent intents can be viewed as output or response labels. Below, we will see how we can provide texts for the agent to make its move in the responses.pl file. Because the same intent label for a user and an agent are handled in very different places, there is no harm in using the same label either, and we can keep things conceptually simple.

When you have added a name for your agent, and the new pattern and rule for generating a self-identifying phrase, you can now Run your Conversational Agent again to hear your agent self-identify itself. |
Visuals
Welcoming page
When a user has visited the Start page and clicked on the Start button, your agent should start by greeting its user. But we would also like to show a webpage that welcomes the user and is shown while the greeting pattern c10 is active and ongoing. Additionally, the new page provides the user with the ability to start talking by clicking on the microphone icon.
