A voice stack built for clinical calls
Most patient contact still starts with a phone call: a refill, a reschedule, a question about lab results. Front desks can't answer every one, and a general-purpose voice agent stumbles on the part that matters most, the medication names and clinical terms. Telnyx gives healthcare teams AI agents that answer around the clock, transcribe clinical language with a medical speech-to-text model, and pronounce drug names from a tested dictionary.
Telnyx owns the stack underneath those calls: the carrier network, the phone numbers, and the GPUs that run speech and language models, colocated with the telephony. Agents connect to your EHR, scheduling and CRM systems through APIs, MCP servers and webhooks, so each call ends with structured data where your team works.
WHY TELNYX?
Built for clinical language
Healthcare calls are full of drug names, dosages and acronyms. Telnyx handles them at both ends of the call, and keeps the rest of the stack on one network and one API.
Hear clinical terms
omi-med-stt-v1 is a medical speech-to-text model trained on clinical dialogue. It runs on Telnyx infrastructure and works across Voice API, TeXML, WebSocket streaming, AI Assistants and REST.
Say drug names right
Our open-source medical pronunciation dictionary covers 966 drugs, clinical terms and acronyms. The Telnyx pack imports in one command and ships only entries measured to improve speech.
Connect your EHR
AI Assistants call your EHR, scheduling and CRM systems as tools through APIs and MCP servers, and send structured call data back by webhook.
Choose your data region
Store recordings, transcripts and conversation data in the US, the EU, Asia Pacific, the Middle East or Canada.
SECURITY AND COMPLIANCE
Built to protect patient data
Telnyx is independently audited for SOC 2 Type II, ISO 27001 and ISO 27701, and is PCI DSS compliant. Calls run on a private network Telnyx owns, and you choose the region where recordings and conversation data are stored. For workloads with protected health information, start with the Architecting HIPAA on Telnyx guide, and find audit reports in the Telnyx Trust Center.
