Mistral AI
Voice Clone creates a permanent copy of any voice from a short audio sample. Record yourself, upload a voice memo, or use any audio clip between 2 and 60 seconds — the AI analyzes the vocal characteristics and creates a reusable voice ID that can be used across all speech generation tools.
The cloned voice captures tone, accent, pitch, and speaking style. Once created, it appears in the My Voices section of Voxtral TTS and can be linked to a specific character — so that character always speaks with the same voice across all their content.
Link a character during creation to auto-fill the voice name, gender, age, and personality traits from the character profile. Or set these manually — name the voice descriptively (like Sophie - French Female or Marcus - Deep Narrator) so you can identify it easily later. Add language tags to indicate which languages this voice handles best.
Your cloned voices are private — only you can see and use them. Each voice stores the original audio sample with a waveform preview so you can always verify which recording it was based on. Edit metadata anytime — rename, change language tags, or update the linked character.
This is the foundation of character voice consistency. Clone once, use everywhere — in TTS for narration, in the content pipeline for multilingual dubbing, and in any workflow where your character needs to speak.

Best results
Clear Audio, Minimal Background Noise
Record in a quiet environment. Background music, echo, or ambient noise gets baked into the cloned voice. A clean recording produces a clean clone — use a decent microphone and a quiet room.
10–30 Seconds Is the Sweet Spot
Mistral accepts 2–60 seconds, but 10–30 seconds of natural speech gives the best balance. Too short and the AI lacks vocal variety to learn from. Too long adds diminishing returns and upload time.
Speak Naturally, Not Robotically
Read a paragraph conversationally — vary your pitch, pause naturally, use normal expression. The AI learns from your delivery style. Monotone samples produce monotone clones.
Link to a Character
Linking a voice to a character auto-fills name, gender, age, and traits. It also makes the voice appear first when that character is selected in TTS — keeping your workflow fast and organized.
Name Voices Descriptively
Use names like Sophie - Warm French or Marcus - Deep English rather than Voice 1. When you have multiple cloned voices, clear names save time finding the right one.
Your Voices Are Private
Cloned voices are only visible to you. Other users cannot see, access, or use your voice clones. Only voices marked as presets by the admin appear for all users.
