03 / PHONE & EVIDENCE / Developer release

Check AI call results against the other party’s words

“Done” is not evidence.

The phone agent says the booking is confirmed. What did the person on the other end actually say? Oathra links each date, amount and confirmation to their words in the call transcript.

The first button opens a public sample check. It does not place a live call or create a booking in an external system.

WHAT TO LOOK FOR

What did the other party say?

Follow the result back to the words that support it.

FIRST THING TO TRYMatch dates, amounts and confirmation language to a public sample transcript.

Setup, scope & license

Apache-2.0 · A spoken agreement does not prove a booking exists in a business system. Simulation and real-call evidence are separate. Real calls need configuration and incur costs.

  • Millisecond spansEach verified field points to the other party’s speech span
  • Speech is the evidenceOnly the spoken agreement is verified, never a system record
  • Apache-2.0Runtime, CLI and evaluation harness are public

WHAT THE FILM SHOWS

From the reported result back to the conversation.

  1. Converse

    Keep the exchange between the phone agent and the other party.

  2. Extract evidence

    Tie dates, prices and confirmation to the actual transcript.

  3. Separate the result

    Do not confuse spoken agreement with a record created in an external business system.

TRY IT

Start by comparing the claim with the evidence.

The public simulator ties dates, amounts and confirmation language to the other party’s words. It is not proof of a live call or an external booking-system entry.

CURRENT BOUNDARIES

Availability and development.

Current scope

A spoken agreement does not prove a booking exists in a business system. Simulation and real-call evidence are separate. Real calls need configuration and incur costs.

The separate design film is a proposal for a future interface. It is not a demonstration of the current product or proof that the proposed UI has shipped.

(05) What it can do

The agent saying “done” is not evidence.

F-01 / CALL

An AI agent makes the call

The agent phones a business to book or order, negotiating dates, amounts and conditions. Real calls need configuration and cost money, and the 100-call evaluation is not complete.

  • Voice calls
  • Booking and ordering
  • Real calls are conditional
F-02 / EVIDENCE

Evidence tied to speech spans

Dates, amounts and confirmation are recorded with the start and end time of the other party’s words. The agent saying “done” does not count.

  • Timestamps
  • Callee speech
  • No self-report
F-03 / BOUNDARY

Agreement is not registration

Verification stops at the spoken agreement. Nothing is written to a booking system or CRM; that check stays a separate step.

  • Explicit boundary
  • No CRM sync
  • Separate step
