The best voice models now sound nearly human. One month of the Humanness Index, 11,000+ blind votes: → Grok TTS: 95 → 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

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. Here’s how it stacks up against other

Barge-in is the opposite side of endpointing. Endpointing asks: 𝗶𝘀 𝘁𝗵𝗲 𝘂𝘀𝗲𝗿 𝗱𝗼𝗻𝗲 𝘀𝗽𝗲𝗮𝗸𝗶𝗻𝗴? Barge-in asks: 𝘀𝗵𝗼𝘂𝗹𝗱 𝘁𝗵𝗲 𝗮𝘀𝘀𝗶𝘀𝘁𝗮𝗻𝘁 𝘀𝘁𝗼𝗽 𝘀𝗽𝗲𝗮𝗸𝗶𝗻𝗴? “yeah” should not cancel playback. “no, wait” probably should. background noise

There are 15 voice agents on the Vapi homepage across 3 use cases × 5 languages. To build these, we protoype and generate all the agents at once in code. This means one wording change applies across all variants and reruns never duplicate assistants.

Reruns never duplicate because the upsert keys on env-var IDs: present > update(id, body) absent > create(body) + prints id Stale id 404s, falls back to create.

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,

@xai Grok TTS is currently #1 on the @Vapi_AI Humanness Index and significantly more affordable than the competition. See for yourself humannessindex.vapi.ai

Your voice agent is talking over a caller who paused to pull up their account number. Raising the silence threshold could help, but it will also make the responses feel laggy. What you need to know is when the turn ended

Evaluating text-to-speech models is hard! Quantitative metrics are important (time to first audio; missing words; variations in volume, pitch, and pacing). But more than any other technology I've ever worked with, people make voice decisions based on "vibes" that are hard

You can feel whether the voice on a call is a human or a machine before you can explain why. Today, @Vapi_AI is launching the Humanness Index™, a crowdsourced leaderboard for model humanness. You are the benchmark. Cast your first vote today: humannessindex.vapi.ai
