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

Question

I am using actions-on-google and Dialogflow to build a social robot for Elderly.

I was wondering how I can easily repeat the last sentence when asked by the user ("repeat please") as often the Senior doesn't hear the sentence the first time.

One way would be to have repeat followup intents in Dialogflow but this is quite heavy since :

• you need to add one after each intent and I have many
• in a multi-user environment you need to keep track of the last sentence for every user ...

Another way would be be to take advantage of Dialogflow Contexts. As you send the message, you can also add that message to a context (for example, you can call it "last_message"). You can then have another Intent that takes as an input context the "last_message" context and, if triggered, uses the value saved in the context to repeat it.

• However, I still have the problem that I need to add a context to every intent I have, which are many.

Does anyone know how to accomplish this in a quicker way? I found this package but it is in JS and I need it Python: https://github.com/SysCoder/VoiceRepeater/pulls .

How do I implement this VoiceRepeater library? Do I put the code under fulfillment function 'repeat' I have made and mapped to an intent called 'repeat' that I have made which responds to utterances such as 'Sorry, could you repeat that'? Also, where do I install the VoiceRepeater library (code: npm install voice-repeater --save)?
