We didn't switch to Sonic 3.5 because it was incrementally better, we switched because nothing else came close… we've seen a 2.9% lift in our conversion and a 12.2% increase in customer engagement.
Reduce call center costs, modernize IVR systems, and maintain PCI compliance with a secure, lightning quick voice AI platform.

Wealth management

Automate FNOL
Remove paperwork from the first notice of loss by letting policyholders describe incidents in their own words—automatically populating your claims system.
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.
No-touch account opening
Setting customers up with new accounts doesn't have to be time-consuming and resource-intensive. AI-powered voice can be used to collect customer information, answer questions, and provide account info, making it easier and faster to onboard new or existing customers with newly opened accounts.
Automated service
Move your IVR systems beyond minor tasks like checking account balances and stock quotes. Our ultra-low-latency voice AI enables human-like conversations that help customers accomplish advanced tasks 24/7 that would normally require live agents. Customers can resolve issues faster, avoid complex menus, and remain satisfied with your services.

Sierra
Cartesia Sonic 3.5 has become one of the top-performing models for us by combining low latency with natural pacing… helping us deliver strong voice quality across a growing set of languages where other models often fall short.
Callers
Sonic 3.5 has been a meaningful upgrade for Callers… latency and naturalness directly impact conversational flow and user success, and the new model noticeably improves both. We've seen more human interactions — especially in high-volume customer conversations where every millisecond and every turn matters.
Take2 AI
We moved from an incumbent TTS provider to Cartesia because of the support experience. After repeated roadblocks with our previous provider, the difference with Cartesia has been transformative — responsive, technical, and genuinely invested in our success.

Sonic 3.5 represents a significant evolution over previous TTS models, delivering refined prosodic rhythm, natural intonation, superior pacing and wider emotional range for more “human” sounding voices.

Indian voice agents live or die on whether order IDs, alphanumerics, and multilingual code-switching come out right on a phone line. Sonic 3.5 handles alphanumerics natively… and lands first audio at 100ms p90.
