Agentic Index
Corti vs Phonic (2026)
Both sell voice infrastructure rather than finished agents, at 10 and 9 of 14.
Corti is built for healthcare developers, with clinical speech recognition, healthcare models and an Agentic Framework offering orchestration, guardrails and an agent library through one API, with audit trails on every call and usage based credits. Phonic is built on proprietary speech to speech foundation models with around 300 millisecond latency, an adaptive decision system rather than rigid state machines, a system of record and cloud or on premise deployment, seed stage and oriented toward healthcare and insurance. Corti brings the clinical domain; Phonic brings the latency and the architecture.
Choose Corti if
- Clinical speech recognition and healthcare specific models are the hard part for you.
- Documented coverage is broader and audit trails on every call are a compliance requirement.
- An agent library shortens the distance between the API and something working.
Choose Phonic if
- Latency around 300 milliseconds is what makes the conversation feel human.
- An adaptive decision system rather than a state machine matches how your calls actually go.
- On premise deployment is a requirement your environment imposes.
