How To Develop A Google Banana App: Getting Started With Dialogflow
Dialogflow provides a new and innovative manner for users to interact with mobile apps by integrating vocalism-based conversational interfaces powered by AI.
The conversational platform allows developers to connect with users via the Google Banana, Amazon Alexa, and other platforms. For the purpose of this post, we will exist focusing on using Dialogflow to create your own chat. A Dialogflow conversation includes how users will invoke the app, the valid things they can say to the banana, and how the banana will answer to them.
In this tutorial, you lot volition larn how to create a uncomplicated Google Assistant awarding with one intent with a static response, and larn to exam your application on the emulator or your personal device.
By the end of our blog series, we will have finished creating a Google Banana app that lets yous schedule appointments to Clearbridge Mobile's Sales Team calendar.
Getting Started: Setting Upwards Your Dialogflow
Creating Your Agent For Your Projection
1. Sign in to Dialogflow. If y'all don't have an account, sign upward using your Google account. Annotation that your Google account will be used to exam your app on whatsoever of your devices logged in to your account with Google Assistant.
2. Create an agent by clicking "Create Agent" on the top left corner. In our instance, nosotros volition proper name our amanuensis "ClearbridgeAppointments". Since nosotros will exist creating this project from scratch, we will use the default values prepare by Google/Dialogflow. This is where we program and train our app.
Implementing An Intent For Your Conversation
iii. Adjacent, we will create an intent. An intent maps the user'south control with actions for your app. This is an important office of Dialogflow equally this is how users volition interact with your app. To create an intent, navigate to "Intents" from the left side menu, then click on "Create Intent". For the purposes of our appointment application, we will be creating a assist intent that helps navigate users through our app. For our help intent, if the user tells the app "I need assist", the app will respond by telling the user "You tin ask me to book an appointment for yous".
four. Start past giving your intent a name. We volition call ours "aid".
5. Then provide sample phrases for your app. These phrases will serve every bit cues for your awarding to option up. Keep in mind, the more phrases your provide, the better your app will exist at comprehending your commands (we will demonstrate the power of Dialogflow's ability to sympathize phrases below.)
6. Next, we will provide an activity name under the "Action" section. This field isn't required for our basic intent to work, simply will be required in the adjacent few blog series when we link our javascript code with our intents.
7. And then, in the "Response" field, write the message that yous would like your intent to render to the user.
8. You lot tin run into how I created my intent in the screenshot. I have provided 6 phrases that I would like my app to listen for and named my action as "tell.aid". Yous can also see the default response that I would like my app to render. After filling out all the information, click "Save". It is not necessary to give your intent an action name when returning static responses. The action name is used to connect our intents with our code later, and so it is good practise to name them.
Enhancing Your Conversation With Entities
9. Congratulations, you've successfully created your first intent! At this point, you lot might exist wondering what the field below "Deportment" is about. This section is for entities. Entities are slot-filling input values that you would similar to become from the user. These values can be used as variables in your functions when you connect your javascript with the intent. Since our help intent doesn't require whatever specific information from the user, I left this department blank for our awarding. Nosotros will embrace more details about Entities in the post-obit blog series.
10. Since our app is equanimous of intents and entities, it's important to understand the differences betwixt them. Equally IBM explains, "intents represent verbs (something a user wants to do) and entities represent nouns (such as the object of, or the context for, an action.)"
Testing Your App
11. At present that we've created our first intent, allow'south test our awarding.
12. There are 2 ways of testing your application with Dialogflow. The simplest and quickest style of checking that your control is working is past using the built-in test console on the right side of the folio. Here, you can type your command, and Dialogflow will render you its response.
Notice that I told Dialogflow "I need help", and it triggered our help intent as expected. But something really absurd happened here! Detect that the phrase "I need help" was non provided to Dialogflow when I was setting upwardly the intent.
This is the beauty of Dialogflow – it is a machine learning program. Dialogflow will recognize like phrases and trigger the intents fifty-fifty though y'all haven't specified information technology in the examples. Although the examination console is quick and easy to utilize, the downside of it is that information technology cannot display images, and other rich displays, which is something that will exist covered in the second blog. To remedy this, Dialogflow has another way of testing using the emulator or your device.
13. To use the emulator, simply navigate to "Integrations" department of the app. Then click "Google Assistant" and then "Exam". This will bring upwards another webpage with an emulator. Outset the conversation by entering "Talk to my test app". This volition showtime our application, and our awarding will exist listening for our command. We can enter "I need help" to our emulator, and information technology will trigger our "help" intent. Alternatively, we can test our app using our personal devices. Open up your Google Assistant on your phone and log in using the account that you used to create this app. Then, say "Talk to my test app". This volition open up the test version of our app. We can now trigger our intents by request the app for help.
Sidenote:
At that place may be an issue with the simulator where the simulator does not work and returns the message
"My test app isn't responding right now. Try once more before long."
In that location have been various answers online to fix this issues.
Still, the best way that I found getting around this issues is by using a carve up testing account to test your application.
Setting Up Your Testing Account
- To ready a separate testing account, click on the Settings Icon on Actions on Google, and navigate to "Permissions".
- And so click on "Add together", and enter the email address of your testing account.
- Then select the part every bit "Project Owner". This is giving full project admission to the electronic mail that you provided in stride 2.
- Click Add, and log into your testing account's email. There should be an invitation email to join the project.
- Click on "Accept Invite". This should pb you to Actions on Google page, where you tin can navigate to the simulator to test your device.
6. Alternatively, after accepting the project invitation on your test account, yous can log into your Google Banana on your mobile device that supports Google Assistant, and invoke your examination app by saying "Okay Google, talk to my test app".
Brand sure to tweak your responses to your liking and exam your terminal production. Testing your app is a vital factor of the development process that ensures proper functionality and an overall high-quality product. It'southward of import to also invite other people to your project so they tin test your app earlier you lot publish it.
That'south everything for this tutorial! If you've fabricated it this far, I want to congratulate yous on making your kickoff app with Dialogflow! Intents and Entities are the fundamental building blocks to creating conversational experiences. In our side by side blog, How to Develop a Google Assistant App: Creating a Fulfillment in Dialogflow we focus on the visual aspect of our application by learning about Fulfillment.
This yr we'll undoubtedly see explosive growth in phonation-enabled devices at present that Google, Amazon, and other massive brands have fabricated vocalism development a lot more accessible to developers. There will be a ascension of companies leveraging voice-activated apps to provide consumers with the power to connect directly and more conveniently with the content they want. If you take whatever questions about Google Actions or voice-enabled apps, feel free to contact united states for more information.
