About Eleven v4 Voice Clone
Eleven v4 Voice Clone speaks your text in a voice cloned from short reference recordings, with Eleven v4's expressive delivery across more than 90 languages.
Upload one or more clean clips of the speaker along with the text to say, and the model speaks it in that voice. Audio tags such as [whispering] or [laughing] direct delivery as with Eleven v4, and the clone can speak languages the reference never did. More and cleaner reference audio, a minute or two in total without music or other voices, gives a closer match. You must have the right to use the voice you upload.

https://hub.oxen.ai/api/ai/chat/completions| Field | Type | Required | Default | Description |
|---|---|---|---|---|
prompt | string | Yes | — | Text to speak, up to 10,000 characters. Put audio tags in square brackets before a line to direct its delivery, e.g. [whispering], [excited]. |
input_audios | array<string> | Yes | — | Clean recordings of the voice to clone, up to 5 clips. A minute or two in total, without music or other speakers, works best. |
voice_rights_confirmed | boolean | Yes | false | I confirm I have the rights and consent to clone this voice. |
remove_background_noise | boolean | No | false | Clean background noise from the samples before cloning. Can lower quality on samples that are already clean. |
language_code | stringnullable | No | — | Optional ISO 639-1 language code (e.g. en, es, ja) to force the language and its text normalization. Leave empty to detect it from the text. |
stability | number | No | 0.5 | Lower values give more varied, expressive delivery; higher values keep the performance consistent across generations. Range: 0 – 1 |
similarity_boost | number | No | 0.75 | How closely the output follows the cloned voice. Higher values match it more closely at some cost to naturalness. Range: 0 – 1 |
seed | integernullable | No | — | Optional seed for best-effort deterministic output. Range: 0 – 4294967295 |
