Phonic Launches End-to-End Speech-to-Speech Platform for Building Voice Agents

Phonic, providers of an end-to-end speech-to-speech platform for building conversational voice agents, has completed a $4 million funding round with investment from Lux Capital and the founders of Replit (Amjad Masad), Hugging Face (Clem Delangue), Applied Intuition (Qasar Younis), and Modal (Erik Bernhardsson).

Phonic has also released a unified end-to-end platform with direct speech-to-speech processing and an intelligent decision system designed for hyper-realistic and dynamic conversations and support.

"Reliability has been a primary blocker of voice AI adoption," said Moin Nadeem, Phonic's co-founder and CEO, in a statement "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 300 millisecong end-to-end latency, enabling organizations to create hyper-realistic voice experiences that customers actually want to engage with."

The platform's intelligent decision system dynamically adapts to unique customer conversations and edge cases, learning from previous calls and knowledge bases to provide reliable responses across a wider range of interactions. It can be deployed either via cloud API or on premises. With built-in observability, evaluations, and support for custom workflows, it adapts to unique business needs and enables sophisticated voice applications for appointment scheduling, claims processing, and customer inquiry handling.

"The entire industry is struggling with reliably guiding conversations toward task-driven goals," said Nikhil Murthy, Phonic co-founder and chief technology officer, in a statement. "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."

"Voice represents a critical but overlooked frontier in AI development," said Grace Isford, a partner at Lux Capital, in a statement. "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."
