Dialogflow - Repeat last sentence (voice) for Social Robot Elderly

Is there a way to have a "Repeat" follow-up intent for existing intents? This "repeat" intent will repeat the previous response except for default fallback.
It's tedious and difficult to maintain if there's a repeat intent for all intent. I've given a thought of adding an event for all the intents, and i think it's also tedious to do this. Also, events will only work if there's a webhook.
You should not use a Followup Intent for handling "repeat'. This is the perfect example of a top-level Intent that is available from any level in the conversation.
You should be storing the information you need to repeat what you just said in parameters in a Context. When the repeat Intent is triggered, use this information to create the response.
The VoiceRepeater library is a drop-in for the actions-on-google v1 library, but illustrates one approach to doing this.
The multivocal library makes this even more transparent and does this for you by default, but is a different approach in other ways from the actions-on-google library.

Hi so I have a problem.
In Dialogflow, when I get a response to end the chat, I would like to ask the user for ratings.
so I've created 2 intents, "endchat" and "endchat2."
They both have the same training phrases, but it appears only endchat2 is being used (the most recently created intent)
How do I ensure that the chatbot randomly chooses an intent after a given response, instead of only using one intent? They have the same training phrases.
An alternate idea is in the attachments. The problem lies that I want the custom payload to only to appear after one of the text responses, (that being text response #1,) but not appear, if the chatbot decides to use text response #2. This is the reason I decide to make two separate intents, but it looks like that's not helping out because the bot is only using one intent.
Remember, Intents represent what the user says and does and not how you respond to that. So there is no way to "randomly choose an Intent" to use to respond.
What you can do, however, is setup a webhook for that Intent and determine how you wish to respond to what the user says. In some cases, you can thank them and end the conversation, while in others you can thank them, ask them the followup question, and set a Context so you can expect their reply.
Having the same / similar training phrase in multiple intents is an anti-pattern of bot design. Ultimately this confuses the bot and it leads to undefined behavior.
This should also trigger an warning in "Validation" with something like "Multiple intents share training phrases which are too similar:..." on the intents.
I want to ask the users a few questions in my welcome intent and depending on their answers give them a particular output.
My problem is that, once the user answers the first question, the agent exits my welcome intent and tries to match with the next intent.
I thought I could solve this by matching it back to the welcome intent.
So ideally it should have gone like this :
Welcome intent -> 1st question -> user answer -> Welcome intent ->2nd question -> and so on
But actually this happens :
Welcome intent -> 1st question -> user answer ->Welcome intent -> 1st question
It will keep asking the first question.
To solve this , I started maintaining a flag for each question.
If question 1 was answered I would set its flag true and then use it to skip the first question when the welcome intent is matched for the second time.
This is a very convoluted way to do it and probably far from the best way to do it.
Can anyone point me in the right direction to implement it?
Thank you.
Edit : I have given up my old method. Let me explain what I want to do and then I can get guidance on the way I should implement it.
I have 16 different outputs and I would like to show one of them to the user depending on their answer to 4 questions. Each question will only have two answers as options and depending on the option chosen by the user for each question , I will pick one of the 16 outputs and display it to the user.
How do I accomplish this using diaglogflow node.js?
First of all remember that an Intent captures what the user says or does and not what you do with that information or how you reply to it. That part is best handled by your fulfillment. While we can use Contexts to limit which Intents will be considered for a user response they are probably most useful in this case to store your state and keep track of which questions have been asked and answered.
Under this scheme, your Intents remain responsible for capturing input and your fulfillment examines this input, changes state based on this input, and sends a reply based on the new state (what it needs to ask next). If the user's responses will be mostly the same (free form, or from the same set of phrases), you can even use the same Intent to capture this input and the fulfillment would use the state and input to determine what logic to execute. If you need different types of input, and thus different Intents, their handlers can still call common functions to do the processing and change the state/reply.
This is further discussed in Thinking for Code: Design conversations not logic
You can use the concept of the follow-up intents in Dialogflow Console to create a chain of questions/answers.
Here is an example of my chain of questions/answers:
Though I still strongly advise you to study also how input/output context works. Especially if you want to collect all user reply parameters in the one final fulfillment of the last step to avoid storing the user inputs in fulfillments attached to every intent of the chain.
I'm new to using Dialogflow,and I want to create a simple DialogFlow bot that can answer basic addition,subtraction,multiplication,division questions.How would I code it that it responds to the specific question asked by the user? For example if I made a math intent, I used the training phase "What's 2 x 3", and I made the response "6". Now, I want to add more training phases and I need the bot to use the correct response. Also, another problem is that it would take an impossible amount of time to teach it every possible math question,so is there code I could use to change that?
The easiest way to be able to answer every combination of math question would be by using a fulfillment webhook. Here you can use code to do the calculations based on the user input. You could create an addition intent where you train the bot to recognize addition input and you would connect it to code in your webhook which can do additions and return the response. You can then also add intents for subtracting, multiplication and divisions and connect each of those intents to code which can do the math.
For the setup, you have two options. You can write code in the inline editor in Dialogflow or host your code in your own server and connect dialogflow to the url of that server. More info on that can be found here.
I’m working on a memory game with multiple levels on Dialogflow. Each correctly guessed question is a separate intent and all 3 questions need to be answered correctly to proceed to the next level. How do I create the game so that the second level (which will be the follow up intent) is only provoked when all 3 questions from the 1st level are answered correctly? Thank you in advance!
Instead of having the followup intent, you can maintain a counter in a parameter (see my answer here for storing parameters).
Enable webhook in all the intents.
Whenever a question is answered, check the validity and if correct increment the counter.
When the counter reaches 3, you can respond back with the response of your choice.
If you want to go by your way then, after answering 3 question correctly you will need to generate an event dynamically via webhook. And the fourth intent should be triggered using that event.
I am trying to jump to a random question with followup event, and at the same time store the question number in the context. But dialogflow only jumps to the event without storing the question number. Is there a way to do followup event and store a context in one intent?
app.intent('Quiz - random', (conv) => {
let rand = Math.floor(Math.random() * quiz_len) + 1;
conv.data.current_qns = rand;
conv.followup(`quiz-question${rand}`);
});
Not really. The point of using conv.followup() is to make it as if the new Intent is the one that was actually triggered by the user. Remember - Intents represent what the user is saying not what you're replying with. You can include a parameter with the redirect, which I guess you can use to send the question, but this still would be the equivalent of a parameter sent by the user.
It isn't entirely clear why you feel you need to direct to a different Intent. Is it just to ask the question as part of the reply? Go ahead and ask it in the Intent handler you're in and store the number in the context directly.
Update
You've indicated in the comments that you want to structure things so you have a "random dispatcher" that then redirects to an Intent to ask a question, and that Intent has a Followup Intent that accepts the right answer (and possibly ones that deal with wrong answers).
This requires you to build a lot of extra Intents for all the various questions, and then the conditions on each question. This requires you to re-build this structure every time you want to add a new question.
Dialogflow works very well to navigate the structure of a conversation - so you don't need to use it to navigate specific questions, answers, and responses. Remember - Intents model what a user says in broad terms, not how our agent responds.
Here is a structure that might work better:
There is an Intent that handles the user asking for a random question. The Intent fulfillment for this (ie - the handler function in your webhook) does the following:
Selects a question
Sets a context to indicate which question is being asked
Sends the context and the question to the user
There is another Intent that handles user responses. All user responses. If this is a multiple choice question, you can set very specific phrases, but otherwise you may need to make this a Fallback Intent that has the context specified above as an Input Context.
Your handler for this compares the answer.
If correct, you clear the context, say so, and ask if they want another question. (Which would then loop to the Intent specified in step 1.)
If incorrect, you make sure the context is still valid and tell them they're wrong. Possibly increase a counter so you don't let them guess indefinitely.
This means you're only building two Intents that handle the question itself. You should add a few more. Here are a few to think about:
What happens if the user doesn't say anything at all? The "No Input" scenario should be handled differently than a bad answer.
If you're asking a multiple choice question, perhaps you'll use a list and need to handle a list response.
Finally, if you're using a list, you may want to do something fancy and use Dialogflow's API to set a Session Entity Type for just that question. This allows you to set what you're expecting (with some aliases) for what is correct and incorrect, and then use a Fallback Intent for the context to say that what the user said didn't make sense.
