How is Voice AI being put to work in the real world? Get a look at what’s happening on the ground with rapid-fire pitches from developers deploying Voice AI in production.
Featuring:
- Kaan Karakaş, Applied AI Engineer at Delphi AI. Kaan works on the agent harness, tool ls that make Delphi's responses sound like the person who created them, across chat and voice calls.
- Siddeshwaraswamy AM, Principal Engineer at Intuit, who leads the technical direction for Invoicing and Payments AI across QuickBooks. He productionized and scaled the Invoice Voice Agent to all QuickBooks customers, building a scalable batch-calling backend and reusable invoicing AI service layer that enables roughly 25% of invoices to be paid the same day.
- Ulrich Gartzke, Founder & CEO at CAREBELLS. His work focuses on social innovation, social entrepreneurship, and the application of emerging technologies to social challenges.
Join us at VapiCon26 to hear how teams are putting Voice AI into action.

We’re excited to welcome Hamming AI as a Startup Sponsor of VapiCon 2026!
Hamming AI is the trust and reliability platform for teams deploying voice and chat agents. Before launch, Hamming runs realistic and adversarial conversations to find where agents break. In production, it form with real users. When a failure is found, teams can turn it into a regression test and rerun it after every prompt, model, or workflow change.
Hamming simulates accents, languages, background noise, interruptions, edge cases, and social-engineering attacks. It evaluates conversation quality, latency, tool calls, handoffs, and compliance—creating a continuous reliability loop that helps teams find new weaknesses and verify that fixes still work.

Every voice agent = transcriber + LLM + voice. The hard part is picking the right ones.
So we launched Vapi Model Intelligence, a bundle of two features:
→ Model Presets: Balanced, High Intelligence, Ultra Fast, Cost Saver. Pick one, ship.
→ Model Performance Metrics: data d on real Vapi calls, not labs. Cost, latency, WER for transcribers, intelligence for LLMs, humanness for voices.

voiceSeconds → speech duration required before stopping
backoffSeconds → recovery time before speaking again

Two days into blind voting of voice models on our Humanness Index™, and xAI's Grok TTS model is at the top of the pack.
Its humanness score? 96, just 4 points under a real human voice (100).
The Humanness Index takes one voice and one quote, clones it across every major model, blind for real listeners to score.
