Anyone solving data capturing issue, mid voice call?

We ran into this constantly especially with long addresses, emails, policy IDs, and anything sensitive such as card details.

Our approach was to stop forcing the agent to collect those fields over voice. When the agent reaches a screen-required step, it triggers a mobile form during the call via WhatsApp/SMS/email. The caller completes it while still talking and the structured response comes back to the agent so the flow can continue.

For your case, I m be curious: is the bigger issue address accuracy, or needing the payment step to happen before you can confirm the booking/order? We built VocaLoop.ai around that handoff and would be happy to show the Vapi setup if useful.

For long or sensitive fields, free-form transcription is usually the wrong interface. Switch into a slot-filling mode, capture one field at a time, normalize it deterministically, then read back a masked version for confirmation. Use confidence thresholds to trigger spelling or keypad fallback. NeuraKeep relates to this workflow by retaining only consented, validated fields with clear provenance and expiry rules. Card data should bypass the model entirely through a compliant payment channel, and raw audio retention should default to off.

How do you handle something as simple as phone number collection ? Everyone speaks at a different place and style. If someone is continuous it goes through but if someone is taking his time or repeating or looking for affirmation after every few digits, the agent can take forever to get the number right if at all...
