Phonic-1

Phonic is an AI-powered voice agent platform that enables businesses to build and deploy natural, real-time conversational assistants for phone calls and other voice interactions. Its Phonic-1 speech-to-speech model processes spoken audio directly, allowing agents to understand tone, hesitation, and conversational context without relying on separate transcription and text-to-speech systems. The platform delivers responses in approximately 600 milliseconds and supports more than 50 languages with seamless language switching during conversations. Its AI agents can execute tool calls while a person is still speaking, enabling real-time information retrieval, workflow automation, and task completion. Developers can create and manage voice agents using APIs, Python and TypeScript SDKs, a command-line interface, or a no-code agent builder. Phonic also provides conversation monitoring, enterprise security controls, and flexible cloud, private infrastructure, and self-hosted deployment options

GPT-Live-1 is one of the two new GPT-Live voice models rolling out to ChatGPT users globally, built to make talking with AI feel much more like having a real conversation. It is powered by a full-duplex architecture, so it can listen and speak at the same time instead of waiting for one rigid turn to end before the next begins. During conversations, GPT-Live-1 can show it is paying attention with short acknowledgments, engage in quick back-and-forth, pause when the user needs a moment to think, or stay quiet when asked to listen. It continuously processes input while generating output, allowing the model to decide many times per second whether to speak, keep listening, pause, interrupt, or invoke a tool. GPT-Live-1 also separates natural interaction from deeper work: when a question requires web search, reasoning, or more agentic capabilities, it can delegate the task to a frontier model behind the scenes and bring the result back when it is ready.
