What critics are saying

  • OpenAI, Google, and Salesforce-Cresta can bundle voice agents into existing platforms.

  • If enterprise buyers standardize on in-house voice stacks, Phonic becomes a feature, not a company.

Phonic raises $27.5M Series A and launches Phonic-1, a top-ranked speech-to-speech model

Phonic has launched Phonic-1, a speech-to-speech model for agentic tasks, and raised a $27.5M Series A led by First Round. Lux Capital, Felicis, Definition, and Essence VC also took part, bringing total funding to $31.5M. Phonic says Phonic-1 ranks first on the Artificial Analysis Speech to Speech Index and has the highest task success rate on agentic tasks at the lowest latency. It can act while a caller is still talking, so answers are ready when the caller stops. The model is trained on 50+ languages and can switch languages mid-conversation. It scored 83.2 on Sierra's multilingual full-duplex τ-Voice benchmark, ahead of GPT-Live-1 at 79.9. Phonic now powers calls across six continents for customers including Ashby, Maven AGI, and Rho.
