Voxtral TTS

Voxtral TTS is a frontier, open-weights text-to-speech model designed for enterprises looking to own their voice AI stack. It produces lifelike speech for voice agents and is built for low-latency streaming, making it ideal for applications where real-time voice interaction is crucial. The model excels at contextual understanding and speaker modeling, capturing how a specific person naturally speaks, including their natural pauses, rhythm, intonation, and emotional dexterity.

Voxtral TTS works by taking a voice prompt and a text prompt in one of the 9 supported languages, and then using a transformer backbone to predict a semantic token. The flow-matching transformer then runs 16 function evaluations to produce the acoustic latent. This process allows for fast and adaptable text-to-speech conversion, making it suitable for a wide range of applications, from voice assistants to audio books. The model is also capable of zero-shot cross-lingual voice adaptation, enabling it to generate speech in one language with a voice prompt from another language.

Enterprises with complex voice workflow needs are likely to get the most value from Voxtral TTS. The model's ability to produce lifelike speech, combined with its low latency and adaptability, makes it an ideal solution for companies looking to enhance their customer experience through voice interactions. Additionally, the model's support for multiple languages and dialects makes it a great choice for global enterprises with diverse customer bases.
