This tutorial walks through building a flow for collecting long digit and alphanumeric sequences where the end-user can speak a few characters at a time. A webhook allows you to validate and confirm the sequence one section at a time, making it easy for end-users to correct the agent when it mishears "BVP" as "BBV", for example.
The lessons in the tutorial include:
- Using regexp entities with auto speech adaptation.
- Building webhooks to loop slot-filling.
- Using contexts to carry data between intents.
The final interaction will behave like this:
| Participant | Dialog |
|---|---|
| End-user | Check my order. |
| Agent | What is your sequence? Please pause after a few characters so I can confirm as we go. |
| End-user | 12ABC |
| Agent | 12ABC. Okay, continue. |
| End-user | 34DE |
| Agent | 12ABC34BE. Okay, continue. |
| End-user | No that's not right. |
| Agent | Let's try again. What comes after 12ABC ? |
| End-user | 34DE |
| Agent | 12ABC34DE. Okay, continue. |
| End-user | That's it. |
Finally, the webhook validates the full sequence and proceeeds with the rest of your flow.
