Your voice agent works in the demo. The question is what happens when a real caller introduces complexities that you didnโt test for.
๐ฉ๐ฎ๐ฝ๐ถ ๐ฆ๐ถ๐บ๐๐น๐ฎ๐๐ถ๐ผ๐ป๐ ๐ถ๐ ๐น๐ถ๐๐ฒ. Build, test, iterate, and monitor in one platform:
Native to Vapi, with full context of your agents:
โ AI testers with personalities + scenarios modeled on your real callers
โ tool mocks for failure paths you can't produce on demand
โ explainable pass/fail results with full transcripts
Know your agent works before your customer finds out it doesn't. Read the blog:

Voice AI Live: Using Deepgram Models in Vapi
The top of the Humanness Indexโข changed twice in one week.
A month ago, the leading score was 95. The gap to human is closing, and the names at the top keep changing.
On a model-agnostic platform, the most human voice is a config change away.

"Build vs. buy" is too vague for voice AI.
With Vapi you choose which layers to own: SIP trunk, STT, TTS, LLM endpoint, tools/webhooks, and defined post-call schemas.
Bring the parts you need without building and maintaining the entire call stack.

The best voice models now sound nearly human.
One month of the Humanness Index, 11,000+ blind votes:
โ Grok TTS: 95
โ real human: 100
The Humanness Index uses the same cloned voice, the same script, and a human recording in the set. Listeners are picking the top models almost as often as the real person.

Congrats to the @cartesia team on Ink-2. Accurate transcription at conversational speed is the foundation on which every voice agent builds, and Ink-2 delivers both. Vapi is built to be modular, so you can run best-in-class models like Ink-2 today as a custom transcriber.

For voice agents, STT has to nail three things - accuracy, turn detection, and latency. If any one falls short, the experience breaks down: the agent misunderstands, interrupts, or just feels slow.
We built Ink-2 to lead on all three. Hereโs how it stacks up against other providers: link in comments.

Excited to see what everyone builds today!
Two days into blind voting of voice models on our Humanness Indexโข, 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, then plays the results blind for real listeners to score.
Hear it, cast your votes, and contribute to the leaderboard ๐

@xai Grok TTS is currently #1# on the @Vapi_AI Humanness Index and significantly more affordable than the competition.
