How it works

Real calls. Real transcripts.
Real confidence.

01 — CONNECT

Add your Fonio phone number

Paste the phone number your Fonio agent answers. vspec dials it directly — no API integration or platform access needed from your side.

02 — DEFINE

Define expected behaviors

Write scenarios describing what callers say and what your Fonio agent must respond or accomplish. Keep it simple or go deep on edge cases.

03 — RUN

Automated pass/fail reporting

Kick off tests from the dashboard or your CI pipeline. vspec returns a full transcript and a clear pass/fail for each defined check.

Prompt — caller script
You are a frustrated customer calling about a missing order. Mention the problem, provide your order number (12345) when asked, and push back once if the first resolution offered is a refund — you want the item re-shipped.
Expectation
Agent acknowledges the issue, collects the order number, and offers a concrete resolution — either re-shipment or a clear next step — without needing to escalate to a human.
Coverage

Test the flows that
matter most.

Conversation flow integrity

Verify that your Fonio agent follows the intended conversation structure from start to finish, including conditional branches and handoffs.

Response accuracy

Check that your agent's answers are factually correct and aligned with your knowledge base — not hallucinating or going off-script.

Escalation & handoff testing

Ensure that the Fonio agent correctly escalates to a human agent when triggered and communicates the handoff clearly to the caller.

Tone & compliance checks

Validate that regulated or sensitive conversations stay within approved language boundaries and meet your compliance requirements.
