Modulate, the frontier audio AI company, has announced new investments from Twilio Ventures and technology entrepreneur Paul English, co-founder of Kayak, alongside significant advancements to its Velma audio intelligence platform. The updates enable enterprises to identify AI callers in real time and gain greater visibility into the performance of AI voice agents. The investments follow Modulate’s recently announced $25 million in funding led by Future Ventures, and come as the company expands its technology to address growing demand for enterprise.

Already putting that funding to work, Modulate has released new updates to its Velma audio intelligence platform designed to address two converging trends: a growing flood of calls placed by personal AI voice agents, such as Meta’s Muse, and the continued rise of synthetic voice and deepfake threats. The updates also give enterprises greater visibility into the increasingly complex conversations taking place between humans and AI.

Modulate’s latest models have reduced the median time to identify a synthetic voice from 2.25 seconds to 1.6 seconds, while maintaining greater than 99.1% detection accuracy on real world AI and human voice calls. The technology is designed to identify synthetic callers quickly enough for enterprises to route, flag or respond to AI-generated calls while the interaction is still underway.

“We’re reaching a point where AI agents will be calling businesses, talking to customers, and interacting with other AI agents every day,” said Carter Huffman, CEO and co-founder of Modulate in a press release. “Call operators – human or AI agent – must be able to recognize what’s happening in those conversations and respond appropriately while the interaction is still ongoing.
