About

Grok Voice Think Fast 2.0 is xAI’s flagship voice model for building real-time assistants, phone agents, and interactive voice systems that stream audio and text bidirectionally over WebSocket. Developers can configure system instructions, high or no reasoning effort, built-in or custom voices, automatic server-side voice activity detection, silence duration, idle re-engagement, playback speed, and session resumption after temporary disconnects. It accepts PCM, G.711 μ-law, G.711 A-law, and Opus audio through JSON or raw binary frames, with configurable PCM sample rates from telephone quality to 48 kHz. It supports more than 20 languages with native-quality accents, automatic language detection, natural responses in the speaker’s language, and seamless code-switching. Language hints and up to 100 key terms improve transcription of regional speech, names, products, codes, addresses, and specialized terminology, while pronunciation replacements correct spoken output.

About

Kukarella is an AI-powered audio and voice-content platform that enables users to create professional voice-overs, multi-speaker dialogues, transcriptions, and visual content all within one integrated environment.

It also supports audio transcription of uploads and online videos, extraction of text from webpages and images, voice-cloning for personalized narration, and a dialogue-generation tool that creates scripted conversations with distinct AI voices assigned automatically. In addition, users can translate and dub content into multiple languages, generate matching images or videos to complement their audio, and streamline workflows for e-learning, corporate narration, IVR voice-over, and multilingual content production.
