What's the best voice agent API for healthcare scheduling?

One with speech accuracy on clinical terms and alphanumerics. The AssemblyAI Voice Agent API is built on Universal-3.5 Pro Realtime and supports Medical Mode, at a flat $4.50/hr through one WebSocket.

Can the agent understand medication and insurance terms?

Yes — add domain: "medical-v1" and pass member-ID and drug keyterms for accurate capture.

How much does the healthcare Voice Agent API cost?

The Voice Agent API is a flat $4.50/hr bundling STT, LLM, and TTS; Medical Mode applies to the underlying realtime STT.

Is it suitable for PHI-handling agents?

AssemblyAI is a business associate under HIPAA and signs a standard BAA; PHI redaction and SOC 2 Type 2 apply.

What's the latency for a healthcare voice agent?

~1s end-to-end for the Voice Agent API; ~150ms P50 for the underlying realtime transcription.

Does it work with LiveKit or Pipecat?

Yes — AssemblyAI ships drop-in plugins for both open-source voice frameworks.

Healthcare voice agents

Voice agents that hear medications and member IDs correctly

Scheduling, insurance verification, and triage agents fail on the details — a misheard drug name or member ID breaks the whole call. Build on the Voice Agent API, with Medical Mode accuracy underneath, so the agent gets clinical terms and alphanumerics right. One WebSocket, flat $4.50/hr.

Medical accuracy inside your voice agent

Medical Mode runs on the realtime transcription under your voice agent — add one parameter, no separate STT integration.

from assemblyai.streaming.v3 import StreamingClient, StreamingParameters

client = StreamingClient(api_key="YOUR_API_KEY")

# Healthcare voice agent: scheduling + insurance verification
client.connect(StreamingParameters(
    speech_model="universal-3-5-pro",
    domain="medical-v1",
    keyterms_prompt=["member ID", "prior authorization", "metformin", "copay"],
))

Entity + alphanumeric accuracy

Member IDs, dates, and drug names captured reliably.

Universal-3.5 Pro Realtime

One API, not three

The Voice Agent API replaces separate STT/LLM/TTS with one WebSocket, one bill, ~1s end-to-end latency, flat $4.50/hr.

Voice Agent API

Short-utterance handling
