Key uses for Cartesia voice AI in customer service

Help customers 24/7

Provide troubleshooting, billing management, and product information without keeping customers on hold or disrupting staff during busy hours.

Modernize IVR

Replace frustrating menu trees with real-time virtual agents that can personalize calls for a better, more human support experience.

Scale outbound communications

Call customers for follow-up surveys, appointment reminders, and delivery notifications, without dramatically increasing costs.

Low-latency, dynamic voices for customer service

No abandoned calls

Live agents are expensive, and traditional IVR systems frustrate customers. But with fast, natural-sounding voice AI answering the call, you can handle high volume without irritating customers. By eliminating wait times and the endless menu trees that drive customers to abandon calls, you can retain customers and continue opening new opportunities.

Service their way

Give customers the experience they want by adding 24/7 voice assistance to your support options. Our ultra-low-latency voice AI enables human-like conversations that can complement your existing text-based support like chatbots and SMS. Customers can get issues resolved faster, avoid frustrating IVR systems, and stay engaged with your services.

Improved metrics

Incorporating conversational voice AI gives customers a better experience even as your needs scale. It can help reduce average resolution time, increase ticket resolution rates, and boost CSAT, making your call center a more effective and efficient part of your business.
