xAI Launches Grok Voice Agent Builder in Beta
xAI
xAI launched Voice Agent Builder in beta: a no-code platform that configures production voice agents in about two minutes using a single end-to-end speech-to-speech model delivering sub-second latency. Features include telephony, 80+ voices with cloning, 25+ language support with mid-conversation switching, calendar/email/API tool calls, and call-level observability. Pricing starts at $0.05/min; every account receives a complimentary phone number.
Why it matters
Collapses the standard three-vendor voice AI stack (STT + LLM + TTS) into a single integrated platform and undercuts comparable services (ElevenLabs, Vapi) on per-minute price.
Importance: 3/5
Notable product launch: single-model end-to-end voice agent platform with aggressive pricing undercutting multi-vendor stacks
