How to build a voice agent

Voice Agents: The Next Revolution in AI Accessibility 🎤

Voice agents represent a significant step forward in making AI more accessible and user-friendly.

Unlike traditional text-based interactions, voice agents open up new possibilities for hands-free operation, greater accessibility, and more human-like conversations. Their usefulness doesn’t just stop at scenarios where typing is limited, we believe a vast majority of existing web and mobile user experiences could be upgraded to support voice-based inputs. Typically, an inbox & calendar application could support voice for an AI assistant that improves writing and schedules meeting.

By allowing people to communicate with AI systems through natural speech —both for input and output— voice agents create a more intuitive interaction experience across a lot of industries, from E-commerce to software development.

How Our Voice Agent Template Works

Powering our new template is OpenAI's Realtime API, which delivers the low latency needed for seamless voice interactions and supports various input and output formats. The template features a LangGraph ReAct agent at its foundation, providing the reasoning capabilities needed to take actions based on user input.

What makes this template special:

Real-time audio streaming using WebSockets for bidirectional communication

Tool-calling capabilities via pre-built or custom Blaxel Functions

Very-low-latency infrastructure for human-like conversational flow

Support for both batch and real-time audio processing
