The tool understands how to add natural pauses, rhythm, and intonation to make the speech sound human like. It is also very fast, delivering audio quickly which is important for real-time applications like voice assistants. You can also easily train it to use new voices with just a small amount of reference audio, capturing unique accents and speaking styles. It performs as well as or better than other leading text-to-speech services in terms of quality and speed.

Use Cases

This tool is ideal for businesses that need voice agents for customer support. It can help voice agents respond to customer questions using speech that sounds natural and matches the company's brand. It can be added to existing phone systems to provide automated spoken answers.

Pricing

Voxtral TTS is available through an API for $0.016 for every 1,000 characters. A version of the model with several example voices is also available as open weights.

Vibes

Human tests show that Voxtral TTS sounds more natural than ElevenLabs Flash v2.5 while being just as fast. It also matches ElevenLabs v3 in quality and can be directed to use specific emotions.

Additional Information

Voxtral TTS is built using advanced technology called a transformer-based, autoregressive, flow-matching architecture. It is designed to process audio efficiently. Users can try out the model in Mistral Studio.
