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

KugelAudio is the most realistic speech AI platform, combining text-to-speech, speech-to-text, and voice-to-voice in one stack. With 39-50ms inference latency (lowest on the market), 30-second voice cloning, on-premises deployment, and industry-leading accuracy on email addresses, IBANs, and phone numbers, it's built for production voice applications where quality and compliance matter. It's a strong fit for voice bots and conversational agents that need to handle structured data without misreads, real-time applications requiring sub-50ms latency, and regulated industries like banking, insurance, healthcare, and the public sector that need on-premises or EU-sovereign deployment. Beyond enterprise voice automation, KugelAudio also powers branded voice experiences through natural cloning from 30 seconds of audio, multilingual products across over 30 languages German, English, French, and Italian, and media or content production needing the most realistic synthetic voices available.

Audience

Software developers, AI engineers, machine-learning teams, and robotics developers building voice agents, speech-enabled applications, and real-time audio pipelines.

Audience

KugelAudio is for teams shipping production voice applications where quality, latency, and compliance are non-negotiable, from conversational AI and contact-center platforms to banks, insurers, healthcare, and public-sector deployments with strict GDPR or on-premises requirements. It's equally suited to media, audiobook, e-learning, gaming, and accessibility teams that need realistic multilingual speech, fast voice cloning, and the freedom to host on managed API, EU-sovereign cloud, or fully air-gapped infrastructure.
