About the company
Assort Health provides tailored voice AI solutions for healthcare practices, making exceptional care accessible anytime, anywhere. Their industry-leading specialty-specific AI agents have facilitated over 5 million patient interactions, serving more than 140 clinics across the country. By integrating seamlessly with major EMR/EHR systems, Assort helps medical practices improve their operational efficiency. The solution enables overwhelmed healthcare staff to offload routine, logistics-focused calls to AI agents, allowing them to focus their energy on more strategic and meaningful patient interactions.
The Challenge
Healthcare providers face critical operational challenges: severe staffing shortages in call centers, escalating costs, and frustrating hold times for patients. Assort's solution must navigate complex scheduling rules unique to each practice while handling thousands of patient calls with consistently low latency, high accuracy, and full regulatory compliance.
The Solution
Cartesia's voice AI technology enables Assort Health to transform patient communication while supporting healthcare staff:
- Low Latency: Sonic achieves a time-to-first-audio of 90ms, ensuring quick responses that enhance patient satisfaction.
- Voice Quality: Cartesia achieves exceptional voice clarity at lower frequencies (8kHz) - crucial for phone interactions - meeting or exceeding competitor quality while using fewer resources.
- Near-Perfect Transcript Following: Standard 90% accuracy isn't sufficient for healthcare. Cartesia excels across 2,000+ edge cases, handling complex medical terminology, dates, times, and drug names with precision - essential for patient safety and trust.
- Reliability: Cartesia's infrastructure maintains consistent performance even during high-volume periods, ensuring healthcare operations continue smoothly around the clock.
The following audio demo showcases Cartesia's voice model delivering ultra-low latency responses with natural conversation flow. It expertly handles complex information including dates, addresses, medical terminology, and insurance details while maintaining context awareness throughout the scheduling process.

VA: Great, I'd be happy to help schedule an appointment for you. I see that you already have an appointment with Dr. Peter Kim on Friday, January 31st, at 10: 30am at our Dedham location. Would you like to reschedule it? Or keep it and continue scheduling a new appointment?
Jeff: Yeah, that's for my wrist, so I'd like to schedule a new appointment, please.
VA: Got it. Let's proceed with scheduling your new appointment. What is the reason for your visit?
Jeff: Uh, I think I hurt my shoulder playing tennis. I'm really having trouble moving it around.
VA: I'm sorry to hear about your shoulder issue, Jeff. It sounds like you might need to get that checked out as soon as possible. Let's go ahead and schedule an appointment for you. The earliest we have available is this Friday, January 24th at 2pm with Dr. Alan Curtis.
