It sets a new record for resolving customer support calls, has class-leading latency at under one second, and costs less than other frontier models. Grok Voice powers millions of conversations a day across Tesla and SpaceX, and is available today in the API at the same price as its predecessor. ## [The Most Accurate Voice Model](https://x.ai/news/grok-voice-3#the-most-accurate-voice-model) In Artificial Analysis’s independent testing, Grok Voice 3.0 ranks #1 on the Speech-to-Speech Index, with a score of 86.9. The Index combines speech reasoning, τ-Voice, and preference and task success from blind head-to-head calls. Grok Voice 3.0 also scores 97% on Full Duplex Bench, a measure of how naturally it handles pauses, turn-taking, and interruptions. Speech-to-speech benchmark comparison between Grok Voice 3.0 and competing models, per Artificial Analysis. | Benchmark | Grok Voice 3.0 (this release) | Grok Voice 2.0 | GPT-Live-1 (Astra, Medium) | Gemini 3.8 Live (Ext. Thinking, High) | | --------- | ----------------------------- | -------------- | -------------------------- | ------------------------------------- | | 86.9 | 81.3 | 83.2 | 82.6 | | | 98.5% | 97.2% | 90.1% | 97.7% | | | 1070 | 1011 | 1048 | 990 | | | 94.8% | 94.6% | 87.4% | 89.1% | | | 97.0% | 95.1% | 94.9% | 91.9% | | τ-Voice measures how well agents handle support calls with diverse accents, background noise, and interruptions. Grok Voice 3.0 scores 71.6%, comparable with GPT-Live-1 (Astra), but at 40% lower latency, setting a new frontier in agent intelligence versus responsiveness. It's also cheaper to run than comparable models. Artificial Analysis measures what each model costs to complete a task in its Big Bench Audio run, and Grok Voice 3.0 comes in under both GPT-Live-1 (Astra, Medium) and GPT-Realtime-2.1. Lower cost per task than comparable models Average cost per task on Artificial Analysis's Big Bench Audio run, USD. Lower is better. On [EVA-Bench](https://servicenow.github.io/eva), ServiceNow’s benchmark for enterprise voice agents, Grok Voice 3.0 achieves the highest accuracy score at 74% and is the best-performing model when jointly scored across accuracy and customer experience. > “Grok Voice 3.0 sets a new Pareto frontier on EVA-Bench, ServiceNow’s open-source benchmark scoring voice agents on accuracy and experience across 200+ realistic enterprise scenarios. It pairs top accuracy with a natural, responsive conversation, setting a new standard for what enterprises can expect from AI on the front line of customer service.” Nitin Aggarwal, Senior Director of Product Management, Agentic Evals and RAI, ServiceNow ## [Used by Millions of Customers at Tesla & SpaceX](https://x.ai/news/grok-voice-3#used-by-millions-of-customers-at-tesla--spacex) Grok Voice 3.0 handles millions of conversations a day in Tesla vehicles. Drivers can use Connectors for simple requests like checking their calendar or answering an email, and Grok Bot for bigger tasks like ordering a coffee or booking dinner—all completely hands-free ([see it on X](https://x.com/Tesla/status/2102430656349544590)). Grok Voice 3.0 also powers Grok Bot’s voice mode. Starlink call centers use Grok Voice to answer 20,000 customer calls every day across multiple languages. Roughly 70% are resolved with no human in the loop, and one in four sales calls ends in a purchase before the caller hangs up. A single agent built on Grok Voice 3.0 verifies customers, troubleshoots hardware, issues credits, and ships replacement equipment. ## [Pricing and Availability](https://x.ai/news/grok-voice-3#pricing-and-availability) Grok Voice 3.0 is available today in the Voice Agent API at [$0.08 / min ($4.80 / hr)](https://docs.x.ai/developers/pricing?campaign=voice-3-blog#voice-api-pricing), the same price as Grok Voice 2.0. Agents using `grok-voice-latest` have already been switched over automatically, with no changes needed. ## Start building with Grok Voice [Try It Free](https://console.x.ai/team/default/voice/agents?campaign=voice-3-blog&utm_source=website&utm_medium=referral&utm_campaign=voice-3-blog) [View Docs](https://docs.x.ai/developers/model-capabilities/audio/voice?campaign=voice-3-blog)
