Gradium on Eden AI: Real-Time Voice AI Models Built in France

Gradium, a Paris-based voice AI company founded in September 2025 by former Kyutai researchers, is now available through Eden AI, offering real-time text-to-speech and speech-to-text models designed for conversational agents. Eden AI reports that Gradium’s EU streaming API delivered initial audio in as little as 70 milliseconds in tests conducted from France, a speed intended to reduce perceived pauses while preserving accuracy in end-to-end voice pipelines. Its EU-hosted routes support EU data residency, while its text-to-speech catalog includes roughly 1,400 voices across 28 accents in English, French, Spanish, German, and Portuguese. Through a single Eden AI API key, developers can access Gradium’s text-to-speech service at $57.80 per million characters and asynchronous speech-to-text or translation services priced per minute, while also easily comparing its output, pricing, and voices with other providers.
