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,

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.

@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

You can feel whether a voice is a person or a machine before you can explain why. Today, we're launching the Humanness Index™, a live ranking of voice AI models, judged by you. Same voices, same quotes, different models. You pick the most human ones and even benchmark them

We released Sonic-3.5 and Ink-2, the #1 streaming models for text to speech and speech to text you can use in your voice agents today. New architectures enable new frontiers for speed and quality. We're now the only provider to have #1 models for both speaking and listening.

"What's the latency?" is the wrong question to ask when your voice agent feels slow. Your users don't care about a benchmark when they feel: - dead air waiting for a response - the agent going quiet mid-reply - being talked over or not being able to interrupt - responses that
