xAI has expanded its Grok Voice lineup by adding 21 new flagship voices alongside the original five. Each voice is multilingual and available through the realtime Voice Agent API, Text to Speech API, and the Grok Voice Agent Builder. The new voices include Lumen, Castor, Naksh, Atlas, Carina, Zagan, Helix, Orion, Luna, and Wellness Support, among others. Each voice is tailored for specific applications such as customer support, characters, commentary, advertising, and education. Users can control speech delivery with tags like [pause] and . All voices support more than 25 languages natively, enabling broad global use. Additionally, the original five voices—Ara, Eve, Leo, Rex, and Sal—have been retrained to improve pacing, phrasing, and emphasis for more natural speech. The Grok Voice Agent Builder allows users to create custom voice agents or clone voices from about a minute of audio. These updates aim to provide versatile and natural-sounding voice options for various professional and creative needs.
