What is Phonic?

Phonic is the most reliable platform for building, evaluating, and deploying voice AI agents.

These voice agents can accomplish tasks — for example, they could verify benefits & eligibility, resolve customer support queries, and schedule appointments.

Why do I want to use Phonic?

Phonic is designed from the ground-up for voice AI agents, including training our own speech models.

Unlike other platforms that might be just text-to-speech with an agent layer on top, our platform is built for the voice agent experience.

The platform comes with batteries included for:

  • the most natural voices
  • conversational features such as “can you say that again slower?” or “could you say that in a whisper?”
  • sub-500ms latency between speech-in and speech-out, as measured by the client.
  • best-in-class pronounciation of URLs, emails, and alphanumerics.
  • enterprise-grade support, security and compliance (HIPAA & SOC2), and uptime (99.9% uptime SLA).

Our voice agents are the highest quality in the business and pricing starts at $0.15 / minute of conversation.
