Woofun AI reports that xAI has launched the Voice Agent Builder, a no-code platform powered by Grok Voice. This tool enables developers to create human-like voice agents with capabilities including telephone access, knowledge retrieval, and security controls, available for $0.05 per minute. The platform integrates speech-to-text, LLMs, and text-to-speech into a single flow to reduce latency and costs compared to traditional multi-service architectures.
