Amazon Lex Simple Voice Chatbot Design

Question

Hi Everyone,

I’m trying to design a simple voice chatbot which is expected to help me achieve these function:

1. The bot needs to be accessible online (via a web link)
2. upon clicking on the link, the **bot** should **initiate** the conversation by asking “how are you doing”
3. the bot records the user answer
4. the bot ends the conversation by saying “Great thank you!”
5. the bot converses with the user by speaking only
6. the user converses with the bot by speaking only

Does anyone here help me out?

Many thanks,
JD

Answer

I think that you may not need a chatbot at all. You could have the web site play a piece of recorded audio upon user landing (e.g.: using [Amazon Polly](https://aws.amazon.com/polly/) if you want to use synthetic voices), then record the answer and use [Amazon Transcribe](https://aws.amazon.com/transcribe/) if you want to turn it into text. Finally, you can play the farewell audio.

You could use [Amazon Lex](https://aws.amazon.com/lex/) for the latter as well, but you'd need to have an intent with utterances that match whatever the user might say.

If you plan to extend the behavior of this very basic system to, for example, fulfill tasks for the user, I'd recommend using Amazon Lex (however, you will still need to trigger the initial audio from the app, as Lex will only respond to user interactions). In that case, you'd need to know what the user might answer and design intents for those tasks that are triggered by utterances that match the user's words.
