xAI has expanded Grok's voice capabilities in a meaningful way — 21 new voices are now live across iOS, Android, and web. It's not just a cosmetic update: the new voices were purpose-built for specific use cases, support more than 25 languages natively, and come alongside upgrades to Grok's original five voices. Here's what you need to know.
How many voices does Grok have now?
With this release, Grok's production voice library grows to 26 total. The five original voices — Ara, Eve, Leo, Rex, and Sal — are still available, and all five received retraining as part of this update. According to xAI, the retraining improved naturalness, pacing, phrasing, and emphasis across the board. The 21 new voices sit on top of that foundation.
What makes the new voices different from the originals?
The new voices were each developed and optimized for a specific professional context. xAI has confirmed use cases including customer support, character voices, commentary, advertising, and education. That kind of specialization matters in practice — a voice tuned for customer support will have different pacing and tone than one designed for narrative character work. Rather than offering 21 variations of the same general-purpose voice, xAI appears to have built these with distinct deployment scenarios in mind.
Do the new voices support languages other than English?
Yes — and this is one of the more significant technical details. All 21 new voices are natively multilingual, with support for over 25 languages. Native multilingual means the voices weren't simply translated or adapted from an English base; they were built to handle multiple languages without the accent artifacts or unnatural phrasing that often comes with post-hoc localization. For anyone using Grok in a non-English context, this is a meaningful step up.
Where exactly are these voices available?
Grok's announcement confirms availability across iOS, Android, and web — so consumer-facing access is immediate regardless of platform. On the developer side, according to xAI, the new voices are also live in the realtime Voice Agent API, the Text-to-Speech API, and the new Grok Voice Agent Builder. That last tool is new: it's a dedicated environment for building voice-enabled agents using Grok's voice infrastructure, which signals xAI is positioning this not just as a chatbot feature but as a platform for third-party voice applications.
Can developers control how the voices deliver speech?
Yes. xAI has confirmed support for speech control tags — including [pause] and <whisper> — that give developers precise control over delivery. This kind of granular control is important for production use cases where timing, emphasis, and tone need to match specific content. It's the difference between a voice that reads text aloud and one that can be directed like a performer.
Do I need to do anything to access the new voices?
No action required. The new voices are available now in the Grok app on iOS, Android, and web. Open the app, navigate to voice settings, and the expanded library should already be there. If you don't see the new options immediately, a quick app update or cache refresh typically resolves it. Developers accessing through the API can reference the new voice IDs in the xAI documentation directly.
Twenty-six voices with purpose-built specializations and native multilingual support puts Grok's voice layer in noticeably different territory than where it started. The real test will be how well the specialized voices hold up in actual use — customer support and character work are demanding contexts, and purpose-built only matters if the execution delivers. Worth trying a few before settling on a default.
