Best AI Healthcare Voice Agents

Assort Health is the most complete patient-access voice agent for outpatient practices. It answers and makes calls around the clock for scheduling, intake, referrals, refills, lab requests, eligibility checks and payments, then writes the details back to the EHR. It covers 23+ specialties, from orthopaedics and dermatology to cardiology and oncology.

It also has the best independent signal in this category. KLAS, the health IT research firm, published a spotlight on Assort in August 2026: customers gave it A+ ratings for likelihood to recommend and fair charging, and a 94.5 overall score. KLAS warns the sample is small. Assort's outcome numbers, such as 5% more appointments, are vendor figures.

The gaps: security certifications are not listed on its public site, so ask for SOC 2 and BAA terms during procurement, and pricing is quote-only. Its integration is strongest on athenahealth. Pick Assort if you run a busy specialty group and want calls answered and booked end to end. Look elsewhere if you mainly need clinical outreach or payer calls.

Hippocratic AI builds voice agents for calls where clinical judgement matters: post-discharge check-ins, chronic care, screening reminders, medication questions and pharma programmes. Its Polaris system uses several supporting models to double-check the main model on things like drug safety and when to escalate to a nurse. The company says 31,000+ patients have been escalated to nurses and it has had no incidents of harm, which are vendor claims.

It has the strongest compliance set here: HIPAA, HITRUST and SOC 2 Type II, and it takes contractual liability for its outputs. It also sets hard limits: its agents do not diagnose, prescribe, or handle hospice, mental health or children under two.

Weaker points: most safety evidence comes from its own testing with licensed clinicians, not independent studies, and prices are not published. It also does scheduling, but rivals like Assort go deeper on front-desk work. Pick Hippocratic AI for clinical outreach at scale. Skip it if you mainly need a front-desk phone agent for a small practice.

Luma Health is a patient-engagement platform (reminders, self-scheduling, intake, waitlists) with a voice AI agent called Navigator on top. Navigator answers calls, books appointments and verifies insurance. Its September 2026 release added outbound agents that call patients to rebook missed visits and close care gaps, writing bookings back to the EHR. It can also connect to other tools through the Model Context Protocol (MCP).

Luma's strengths are integration and security. It lists bidirectional links with eight major EHRs, including Epic, Oracle Health and MEDITECH, and holds HIPAA, SOC 2, HITRUST and ISO 27001. Customer results are vendor-reported: one customer rescheduled 2.3 times more cancelled visits than with SMS reminders alone.

Navigator is younger than dedicated voice products, so its range of call types is narrower than Assort's or Hippocratic's. Pick Luma if you want voice, text and scheduling from one vendor with strong security. Skip it if you need a specialist voice agent for complex calls.

Hyro sells AI agents to large health system call centres. They handle doctor search, scheduling, prescription refills and call routing across phone, web chat and text. Its customer list is strong: Intermountain Health, Baptist Health, Sutter Health, Hackensack Meridian and Tampa General are named users, and Bon Secours Mercy Health invested in its October 2025 round.

Hyro connects directly to EHRs, including Epic, through API calls, which matters because health systems want bookings made in the real Epic schedule. The company claims it can resolve up to 85% of routine interactions; that is a vendor figure and "up to" is doing a lot of work.

We could not confirm Hyro's security certifications beyond HIPAA from public sources, and pricing is quote-only. Pick Hyro if you run a large, Epic-based system and want a proven call-centre deflection partner. Skip it for small practices, which are not its market.

Infinitus started with the most tedious call in healthcare: phoning an insurance company to check what a patient's plan covers. Its agents dial the payer, get through phone menus, wait on hold, ask the right questions and return structured results. It now covers prior-authorisation follow-up, claim status, refill coordination, patient education and adherence calls, mainly for pharma hub services and specialty pharmacy.

Scale is its strength. The company reports 350M+ interactions automated and says 8 of the top 10 drug makers use it. It holds SOC 2 Type II, signs BAAs and keeps data in US cloud regions. In 2026 it added a member-services suite for health plans, a no-code agent builder called Studio and a call-review engine called Lens.

It is less of a front-desk scheduling tool, and EHR write-back is less central than for Assort or Luma. Outcome figures such as 400% ROI come from vendor case studies. Pick Infinitus if your staff lose hours on hold with payers. Skip it if you need patient scheduling first. For payer workflows beyond calls, see our best AI prior authorization ranking.

Notable is an automation platform for health systems, and voice is one part of it. Its agents also handle registration, intake, referrals, prior authorisation, copay collection and chart review. Voice agents cover jobs such as pre-procedure instructions and inbound calls.

The benefit is breadth: one vendor can automate the call, then the paperwork behind it. Notable holds SOC 2 and ISO 27001:2022 and names large customers including CommonSpirit, MUSC and UC San Diego. Its voice numbers are modest and honest-looking: one customer case shows 25,000+ calls with 57% handled without staff. That is lower than headline claims from some rivals, but it is a real containment figure rather than an "up to" number.

Voice is not Notable's main product, so its call range is narrower than Assort's or Hippocratic's, and prices are not published. Pick Notable if you want one platform for many admin workflows including voice. Skip it if phone calls are your only problem.

Hello Patient is aimed at outpatient practices that want one AI front desk across phone, text and web chat. Its voice assistant, Mia, answers and makes calls 24/7, books visits, and handles follow-ups and billing questions. It serves primary care, urgent care, dermatology, dentistry, optometry, mental health and even veterinary clinics.

Integrations suit smaller and mid-size groups: athenahealth, eClinicalWorks, ModMed, NextGen, AdvancedMD and Veradigm are listed, but Epic is not. The company says it is HIPAA compliant and SOC 2 certified. Its outcome figures (18% more bookings, 95% shorter waits) are vendor claims, and lifetime volume of about 327,000 completed calls is small next to Assort or Hippocratic.

Pick Hello Patient if you run a multi-location outpatient or urgent care group on a non-Epic system and want voice and text from one vendor. Skip it if you are an Epic health system or need clinical outreach.

Parakeet Health is a small company with an interesting deal: it says clients pay only for verified revenue gains above their normal baseline. Its AI handles inbound and outbound work across voice, text, fax and email, including scheduling, referral processing, cancellations and patient recall.

Its integration list is solid for its size, covering Epic, Oracle Health, athenahealth, eClinicalWorks, ModMed and Nextech. It lists HIPAA, SOC 2 and TCPA compliance (TCPA is the US law on automated calls and texts). The 38% appointment lift and 360% ROI are vendor figures from pilots, not independent studies.

The main risk is size. With $3M of seed funding and no later round we could find, it is far smaller than Assort or Hippocratic. Pick Parakeet if you want low financial risk and a vendor that shares upside. Skip it if you need a large, long-established partner for a big health system.
