Phonic’s New Voice Model Tops Agentic AI Speech Benchmark

The Phonic-1 system earned a score of 87.1 on the Artificial Analysis speech-to-speech index, outperforming xAI’s Grok Voice 3.0 for its ability to handle agentic voice tasks. The model completed 79.9% of customer-service simulations with 0.61 seconds to first audio. Phonic says the model is the only one capable of executing tool lookups and bookings while a user is still talking, allowing the system to respond 1.1 seconds after a caller stopped in a demo, compared to 15.7 seconds for OpenAI’s GPT-Live.

The 10 person startup recently raised a $27.5M Series A led by First Round, with participation from Lux Capital, Felicis and Definition, bringing its total funding to $31.5M. Its speech technology is currently used to power AI job interviews for recruiting platform Ashby across 25 countries.
