Voice AI for Customer Support

Customers find voice support more natural and reassuring—hearing a real voice instills trust and provides comfort that automated text responses often lack. As brands grow, they encounter a dilemma: while the demand for voice interactions rises, many are forced to mask their phone numbers due to high operational overheads. Vonova recognized this challenge and set out to redefine customer support. Vonova’s approach goes beyond simple automation. Their AI voice agents are designed to integrate flawlessly with existing systems while offering the empathy and adaptability that traditional call centers cannot match. The incorporation of Hume’s EVI was crucial to this transformation, adding a layer of emotional intelligence to every customer interaction.

The Challenge

Customers find voice support more natural and reassuring—hearing a real voice provides the trust and comfort that automated text responses often lack. But as brands grow, they face a dilemma: while demand for voice interactions rises, many are forced to hide phone numbers due to high operational costs.

Vonova needed AI voice agents that could integrate seamlessly with existing systems while offering the empathy and adaptability that traditional call centers cannot match at scale.

The Solution: Emotionally Intelligent Voice Agents

Hume's EVI provided the critical emotional intelligence layer that transformed Vonova's voice agents with:

Emotional Understanding: EVI enables agents to detect and interpret customer emotions. When a frustrated caller exclaimed, "I've called a thousand times!", the system responded with "I apologize for the inconvenience" in a tone that conveyed genuine understanding.

Dynamic Adaptability: Agents can adjust their speech speed for elderly users and handle complex tasks like collecting email addresses, ensuring every interaction is smooth and precise.

Authentic Connections: In one instance, a customer called about disabling sound effects on her automatic cat feeder. The EVI-powered agent not only guided her through the solution but showed genuine empathy for her cat, winning the customer's trust.

Results

Vonova's EVI-powered voice agents deliver measurable impact:

  • 40% reduction in operational costs compared to traditional call centers
  • 20% increase in AI resolution rate without human intervention compared to other voice models
  • Seamless integration with no additional development effort required
  • Usage-based pricing allows businesses of all sizes to offer premium voice support

This partnership shows that Hume's EVI can transform customer support, offering scalable, cost-effective solutions that exceed the traditional support methods. As voice becomes the primary interface for customer interactions, Vonova and Hume are setting the stage for natural, empathic AI communication in the future.
