Gradium

Gradium is a voice AI platform built for developers who need real-time voice, all delivered through a single unified API. It covers ultra-low-latency text-to-speech, speech-to-text, speech-to-speech translation, live translation, voice cloning, and on-device text-to-speech, so you can handle the full range of voice interactions without stitching together multiple vendors.

The platform is designed for building real-time voice agents and conversational applications that feel natural to talk to. You get expressive speech generation, accurate transcription, multilingual support, and speaker cloning, while bidirectional WebSocket streaming keeps conversations flowing with minimal delay. Scalable concurrency means your voice agents can grow from a handful of users to heavy traffic without a redesign.

Deployment is flexible too: run in the cloud, on dedicated instances, or self-hosted and on-premises infrastructure when you need full control over data and performance. Whether you are prototyping a new voice assistant or scaling a production conversational product, Gradium gives you the low-latency building blocks to get there.
