Grok Voice 3.0 Starlink calls: the voice AI answering 20,000 a day

Grok Voice 3.0 Starlink calls are the headline number from xAI's launch on October 14, 2026: according to xAI itself, the voice model now answers about 20,000 calls a day in Starlink phone support, and roughly 70% are resolved with no human. It costs $0.08 per minute, the same as the previous version, and it tops the Artificial Analysis voice index.

What Grok Voice 3.0 is and what it costs

Grok Voice 3.0 is a speech-to-speech model: it listens and answers out loud. It is available in xAI's voice API at $0.08 per minute, which works out to $4.80 per hour and matches the price of Grok Voice 2.0. Agents that used the grok-voice-latest alias switched to the new version automatically.

The three things it does

• It handles interruptions. It scores 97.0% on Full Duplex Bench, the test for turn-taking and interruptions.
• It answers fast. xAI reports a response time under one second and 40% less latency than GPT-Live-1 on the τ-Voice support benchmark.
• It reasons out loud. It reaches 98.5% on Big Bench Audio, which measures reasoning over audio.

Put together, it ranks first on the Artificial Analysis Speech-to-Speech index with 86.9 points, ahead of GPT-Live-1 (83.2) and Gemini 3.8 Live (82.6).

Where Grok Voice 3.0 still loses

It does not win everything. On τ-Voice, the support-call benchmark, Grok Voice 3.0 scores 71.6 while OpenAI's GPT-Live-1 scores 74.5, a gap of almost three points. And the Starlink figure (about 20,000 calls a day, around 70% resolved with no human) is published by xAI itself, not audited by anyone independent.

How to apply it in your business?

If your team answers the phone every day, there is a simple calculation: $4.80 per hour of voice against the cost of covering a night shift. It does not replace human judgment on delicate cases, but it can absorb repetitive calls. The best first step is to list which calls you repeat every day and test which ones a voice agent can resolve.
