Unmute by Kyutai: The French Voice of AI Revolutionizing Vocal Emotion

June 4, 2025 | Voicebots

Voice synthesis takes a leap forward with the unveiling of Unmute by Kyutai, one of the rare AI voice models offering a truly expressive and nuanced French voice. This technology, revealed in late May 2025, marks a major milestone for all stakeholders seeking to integrate natural and emotional AI voice into their voicebots, particularly at Versatik, where the integration of such advances is highly anticipated by the market.

Unmute: A Modular, Fluid, and Emotional Voice AI

Developed by the French laboratory Kyutai, Unmute instantly transforms any large language model (LLM) into an interactive voice agent, thanks to a modular architecture combining real-time speech recognition, text generation, and advanced voice synthesis. Where most solutions struggle to convey emotion or irony in the language of Molière, Unmute stands out for its ability to render French voices rich in nuances, with controlled silences, natural hesitations, and expressiveness rarely achieved in AI voice synthesis.

> "Unmute brings voice, but also emotion, irony, and understanding of silences. The goal is to convert any word generator into an ultra-sophisticated voice assistant."

Why the Market Eagerly Awaits Unmute

At Versatik, we develop multilingual AI voicebots for call automation, customer support, and lead generation. While our current solutions already leverage the best synthetic voices on the market, the need for an authentic French voice capable of conveying emotion and dynamically adapting to context remains strong. Customer feedback is unanimous: fluidity, personalization, and the ability to simulate genuine human conversation have become essential criteria for widespread voicebot adoption.

Unmute precisely addresses this demand by offering:

• Near-zero latency for real-time exchanges
• Voice personalization in just seconds of audio sample
• Intelligent management of pauses and silences for natural dialogues
• Unprecedented expressiveness in French, with voices that convey emotion, irony, or curiosity

Towards Upcoming Integration at Versatik

We are closely monitoring Unmute's evolution and hope to integrate it very soon into our voicebot solutions. This advancement would allow our customers to benefit from even more natural, inclusive, and engaging voice interactions, aligned with French and international market expectations.
