Grok Voice resolves 70% of Starlink support calls

xAI says Grok Voice Think Fast 1.0 autonomously resolves 70% of Starlink support inquiries, converts 20% of sales inquiries, and operates across 28 tools. The company’s launch account says the model supports more than 25 languages and can issue replacements and service credits, although the performance figures come from xAI and its sister company rather than an independent audit. For builders tracking full-duplex voice as an agent interface, the useful benchmark is no longer conversational fluency alone: measure autonomous resolution, conversion, escalation, and tool errors on the deployed workflow.
