Phonic: $4 Million Raised For Speech-To-Speech Platform

By Amit Chowdhry • Apr 6, 2025

Phonic, an end-to-end speech-to-speech platform for building lifelike conversational voice agents, announced a $4 million funding raise from leading investors including Lux Capital and visionary leaders in the AI space including the founders of Replit (Amjad Masad), Hugging Face (Clem Delangue), Applied Intuition (Qasar Younis), and Modal (Erik Bernhardsson).

Voice AI promises to transform customer interactions, but reliability issues have held it back. Disconnected systems and rigid decision trees built for routine conversations, not dynamic edge cases, frustrate customers and force businesses to focus on technical challenges rather than customer needs.

Phonic tackles these challenges through breakthrough innovations: a unified end-to-end platform with direct speech-to-speech processing and an intelligent decision system designed for hyperrealistic and dynamic conversations and support.

The platform’s intelligent decision system represents a fundamental shift from traditional decision trees, which only handle routine conversations. And Phonic’s approach dynamically adapts to unique customer conversations and edge cases, while learning from the organization’s previous calls and knowledge base to provide reliable responses across a broader range of interactions.

Phonic’s platform could be deployed via cloud API or on-premises for organizations with strict security requirements. And with built-in observability, evaluations and support for custom workflows, it adapts to unique business needs. Phonic works with its customers to enable sophisticated voice applications for appointment scheduling, claims processing, and customer inquiry handling.

KEY QUOTES:

“Reliability has been a primary blocker of voice AI adoption. By unifying voice generation, recognition, and interaction in one seamless system, we’ve eliminated the complexity of managing multiple tools. Our platform delivers speech in, speech out, with 300ms end-to-end latency, enabling organizations to create hyperrealistic voice experiences that customers actually want to engage with.”

– Moin Nadeem, Phonic Co-founder and CEO

“Before working with Phonic, we struggled with maintaining our state machine across thousands of calls and navigating complex conversations. After implementing Phonic, we were able to delete significant complexity in our codebase, experience higher voice quality, and achieve better reliability. The reliability and realism are substantially better than what we had before.”

– Sayem Hoque, Founder of Flexbone, an AI data platform for healthcare administration

“The entire industry is struggling with reliably guiding conversations toward task-driven goals. Traditional approaches force organizations to manage rigid decision trees that fail on edge cases. Our intelligent decision system dynamically adapts to each conversation, eliminating the need to manually code for thousands of potential scenarios. Combined with our hyperrealistic voices, we’re delivering voice AI that sounds natural and responds reliably.”

– Nikhil Murthy, Phonic Co-founder and CTO

“Voice represents a critical but overlooked frontier in AI development. What excites us about Phonic is their holistic approach to solving voice infrastructure challenges. Instead of incremental improvements to existing methods, they’ve built an entirely new foundation that unifies all aspects of voice AI. This combination of technical innovation and practical implementation perfectly embodies what we look for at Lux.”
