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 3.0 is a speech-to-speech model offered through the Grok Voice Agent API for developers building real-time voice applications. It accepts audio and text and returns spoken audio or text through a WebSocket session, supporting conversational turn-taking, interruptions, and function calling. Developers can connect the model to custom functions and server-side tools, including web search, X search, collections, and remote MCP servers. The API is intended for interactive voice agents such as customer-support and service-call experiences, and is also used for voice interactions in Tesla vehicles and Grok Bot. Billing is usage-based, with audio charged per minute and text input events billed separately. The API documentation includes setup instructions and examples for Python and JavaScript clients.
