Best 5 AI Voice Agents in Healthcare

There is a dirty secret about healthcare administration. It is not the clinical complexity that is shattering health systems, it is the phones, a missed call, a 15 minute long hold queue. An earlier approval that requires three rounds of manual back and forward. These are not edge cases, they are day-to-day operations of most hospitals.

And over years the industry had been comfortable with it as there was no other alternative. That has changed. In the healthcare sector, the AI voice agents will reach $650.65 million in 2026 and will achieve $11.69 billion by 2035 with a CAGR of 37.85 percent. Such a rate of expansion does not occur in vain and the five platforms listed below are not merely talking about that figure, but actually implementing it.

Why Healthcare Can’t Afford to Wait for AI Voice Agents Anymore

The impetus to automate healthcare work with AI in 2026 is reduced to a set of concurrent workforce pressure and increasing patient demands. It is estimated that AI agents will save the U.S. healthcare system $150 billion dollars per year by 2026 and voice AI usage has already hit a 69 percent adoption rate among tech startups in healthcare specifically in making appointments, triage and pre-screening. On the patient side, 81 percent of consumers now use a healthcare bot or voice agent to assist, which implies that patient comfort with AI-mediated interactions is no longer a critical success factor to adoption, but a requirement.

Technology is no longer the bottleneck. The State of AI survey of 2026 revealed that 25 percent of enterprise leaders claimed that AI has a transformational impact on their organizations more than it did the previous year but 37 percent of the organizations only apply AI to the surface level with minimal impact on underlying processes. In medical care, such pilot production disconnect is where access by patients is lost. The following are the platforms that have already broken that gap.

Hyro.ai

Hyro was created to function in healthcare and nothing more and that choice informs everything about its EHR integrations to its compliance architecture. It operates in a hybrid architecture between large language models and proprietary small language models and healthcare-specific knowledge graphs, i.e. complex patient conversations can be processed without it hallucinating information that it has not been trained on. In the United States alone, more than 30 million patients are already using the Hyro voice and chat platform, which is implemented in over 45 major health systems, such as Sutter Health, Tampa General Hospital, Prisma Health and Piedmont Healthcare.

The platform has recently introduced Proactive Px 2-way outbound communication layer which allows health systems to proactively contact patients through calls and SMS to bridge gaps in care and recapture lost revenue through missed appointments at scale. The outcomes in Tampa General Hospital were the benchmark of what AI voice agents in healthcare are able to accomplish. In two weeks of deployment, the AI agent (named Amy) at Tampa General increased the number of scheduled visits by 21 percent, reduced call abandonment by 56 percent, and decreased average wait times by 2.4 minutes to 6.2 minutes and answered almost half a million calls in its initial months.

Best For: Large health systems and hospital networks looking to have an out-of-the-box, healthcare-native voice and chat solution with Epic EHR integration and omnichannel coverage (phone, web, and SMS).

Pricing: Hyro applies personal enterprise pricing. According to third-party reports, the initial price is about 10,000 USD a month, and the ultimate cost depends on the size of a healthcare system, the number of calls, and the complexity of integration.

Infinitus.ai

Infinitus focuses on the area of healthcare operations that all voice platforms tend to avoid due to their lengthy, complicated, multi-party administrative calls that need to be verified real-time, use cross-system searches and accurate documentation. Prior authorizations, benefits verification and specialty pharmacy coordination. Payer-to-provider calls that are usually 20+ minutes and necessitate trained personnel to conduct them. Infinitus automates it all, the site serves more than 100 million minutes of healthcare discussions, supporting more than one million patients and is a trusted solutions partner to 44 percent of fortune 50 healthcare companies.PR Newswire

Its technical moat is a patented architecture that causes it to be hallucination-free by design, the only platform on this list. Infinitus constructs a discrete action space, a knowledge graph, jointly constructed with each client, which imposes hard constraints on what the AI can and cannot talk about, accompanied by a post-call AI review layer, which transparently checks the accuracy of the interaction after each individual conversation.

Zing Health, a Medicare Advantage plan that provides care to chronically underserved groups, used Infinitus agents to automate the process of assessing the health risk of its members in the initial 60 days of their care cycle and found that this increased the chance of successfully connecting patients to the right care models by 2x.HIT Consultant

Best For: Payers, specialty pharmacies and providers who make high volumes of regulated administrative calls — prior authorization, benefits verification, care coordination — where accuracy and compliance are non-negotiable.

Pricing: The prices are not mentioned although Infinitus is customized to the enterprise level and depends on the volume of calls, usage and level of integration.

Hippocratic AI

Hippocratic AI is not about creating a more advanced phone bot. It is creating what it considers to be the infrastructure to bridge the global healthcare staffing gap, one clinical dialogue at a time. Its agents are trained to have direct patient-facing, non-diagnostic communication: chronic care management check-ins, post-discharge follow-up calls, medication adherence follow-ups, health risk assessment, and pre-visit preparation. Hippocratic AI has delivered in excess of 115 million clinical patient interactions in 15 months post commercial launch without any reported safety incidents, and has established partnerships with over 50 health systems, payers, and pharma customers in 6 countries including Cleveland Clinic, Northwestern Medicine, Moffitt Cancer Center, Guy’s and St Thomas NHS Trust. Hippocratic AI

The proof points are clinically established and warrant the valuation. In the real world, the AI service offered by Hippocratic has yielded results like 30% fewer hospital readmissions, 360% more capacity for chronic care management teams, and 89% of members who successfully receive public service announcements in a timely manner. Universal Health Services (UHS) introduced Hippocratic AI post-discharge agents in two subsidiary hospitals and patients rated interactions with AI at an average of 9.0 out of 10, which were strong enough to be quickly expanded by UHS to more locations.

Best For: Health systems, payers and pharma companies seeking to implement patient-facing clinical engagement particularly chronic care, post-discharge follow-up and medication adherence programs at a fraction of the traditional staffing cost.

Pricing: The fundamental pricing model at Hippocratic AI is about $9 per hour per agent in contrast to the average hourly wage of a registered nurse in the U.S. that is about $39.05.

Sully.ai

The majority of AI healthcare chatbots are at the scheduling level with no further inquiry. Sully enters the exam room. It does not install a single tool, it is an integrated AI team: an AI Scribe, AI Triage Nurse, AI Receptionist, AI Medical Coder, AI Pharmacist and AI Consultant, all linked together in a single platform that interconnects with Epic and other major EHR systems. With real-world users noting that it takes the AI scribe about 40 to 50 seconds to produce a first draft clinical note accurate enough to sign off in just a few seconds.

It has been estimated that voice-enabled clinical documentation can save U.S. healthcare providers about $12 billion a year, and Sully notes that the typical organization is able to recover its full ROI in the span of one to three months. During a 10-week enterprise deployment, the Sully ambient AI platform was utilized by 3,442 physicians, involving 303,268 patient interactions — an exceptionally high adoption rate in a health system that has a notorious track record of adopting new technology(Sully).

Best Uses: Enterprise health organizations and clinical teams interested in integrating a wide variety of AI tools — documentation, intake, scheduling and coding — in one modular system that spans end-to-end workflows on behalf of both clinicians and administrators.

Pricing: Sully.ai uses a custom enterprise pricing scheme and is only deployed in enterprises. The average human medical subscribers are priced at $30,000 to $50,000 a year and Sully compares its ROI to the average.
