xAI releases Voice Agent Builder, a voice agent platform: create human-like voice agents without coding.

BlockBeats news, July 1 — xAI today launched a new product, Voice Agent Builder. This is a no-code platform based on Grok Voice that allows developers and operators to quickly build voice agents with human-like conversational capabilities, and it is now available for use. Pricing is $0.05 per minute. The tool is designed for users who want to directly deploy production-grade voice AI applications, lowering the technical barrier to building voice systems from scratch.

According to the official statement, the platform integrates complete capabilities including telephony system access, knowledge retrieval, tool calling, content safety controls, and observability, and it also supports integration with external systems such as existing phone numbers, APIs, and MCP. Compared with traditional voice technology—where three separate types of services are called: speech-to-text, large language models, and text-to-speech—an architecture that leads to increased latency and costs, Voice Agent Builder achieves an integrated voice processing workflow through deep coupling with the Grok model, reducing latency, lowering failure points, and improving overall performance.
