AI voice startup Gradium completes $100 million seed round with NVIDIA participation

Odaily Odaily reports that Gradium, a Paris-based real-time voice AI startup, has announced the completion of a $100 million seed funding round, with NVIDIA participating as an investor.

The company has recently rapidly launched multiple voice AI products, covering tools such as real-time speech-to-text (STT), text-to-speech (TTS), real-time translation (Gradium Translate), and the Phonon audio model. The funding will be used to establish a new office in San Francisco, deeply integrate with the North American AI industry ecosystem, and accelerate the recruitment of global technical talent. Gradium specializes in ultra-low-latency real-time voice interaction models, spun out of the French AI lab Kyutai, with its founding team hailing from top AI institutions such as Google Brain, DeepMind, and Meta.
