About

Decibri is a Rust-based audio library for developers building real-time speech, voice-agent, and audio applications. It provides microphone capture, speaker playback, PCM streaming, audio-file processing, and a command-line interface through Python, Node.js, Rust, and browser APIs. Built-in features include voice activity detection, acoustic echo cancellation, and optional audio conditioning such as denoising, filtering, automatic gain control, and limiting. Developers can stream captured audio to cloud or local speech-to-text services and play generated speech through integrated audio output. Use cases include voice assistants, conversational agents, transcription, wake-word and keyword detection, interactive robotics, full-duplex speech, audio pipelines, and edge devices. Prebuilt native packages support Windows, macOS, and Linux; Python and Node.js packages require no additional build tools. The browser implementation provides capture, energy-based speech detection, and playback.

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.
