Speech synthesis takes a giant leap forward with the introduction of Unmute by Kyutai, one of the few AI voice models offering a truly expressive and nuanced French voice. This technology, unveiled at the end of May 2025, marks a major milestone for everyone looking to integrate a natural and emotional AI voice into their voicebots, especially at Versatik, where such advancements are highly anticipated by the market.
Unmute: A Modular, Smooth, and Emotional AI Voice
Developed by the French laboratory Kyutai, Unmute instantly transforms any large language model (LLM) into an interactive vocal agent, thanks to a modular architecture combining real-time speech recognition, text generation, and advanced speech synthesis. While most solutions struggle to convey emotion or irony in the language of Molière, Unmute stands out with its ability to render French voices rich in nuance, mastering pauses, natural hesitations, and an expressiveness rarely achieved in AI speech synthesis.
“Unmute brings not only voice but also emotion, irony, and the understanding of silences. The goal is to turn any text generator into an ultra-sophisticated voice assistant.”
Why the Market Is Eagerly Awaiting Unmute
At Versatik, we develop multilingual AI voicebots for automating calls, customer support, or lead generation. While our current solutions already use the best synthetic voices on the market, there is still a strong need for an authentic French voice that can convey emotion and adapt dynamically to context. Customer feedback is unanimous: fluency, personalization, and the ability to simulate a genuine human conversation have become essential criteria for the widespread adoption of voicebots.
Unmute meets this demand precisely by offering:
- Near-zero latency for real-time exchanges
- Voice personalization with just a few seconds of audio sample
- Intelligent handling of pauses and silences for natural dialogues
- Unprecedented expressiveness in French, with voices that can convey emotion, irony, or curiosity
Towards Imminent Integration at Versatik
We are closely following Unmute’s development and hope to integrate it into our voicebot solutions very soon.
