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.- Barge-in is the opposite side of endpointing.

- 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,

@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 - Vapi reposted
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 hardYou 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 Indexโข, 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 Indexโข, 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
