Phonic

Phonic builds speech-to-speech models and a platform for voice agents that take phone calls. It is aimed at teams in recruiting, healthcare, logistics and customer support who want agents that respond quickly and handle interruptions naturally.

Instead of converting speech to text and back, the models listen to the caller's audio directly, so tone and hesitation are part of what the agent hears. The site claims responses in about 500 ms and support for more than 50 languages, and a larger model supervises tool calls and reasoning.

You can start building from the docs or call a demo number to talk to an agent. Example workflows on the site include candidate screening, patient intake and triage, driver check-ins and dispatch, and resolving support calls with a handoff to a human.
