Do all voices support all 30 languages?

On Pro with Omni, cloned voices, designed voices, and the library voices that support Omni speak all 30 supported languages; a cloned voice keeps the accent of its recording. Subscriber includes the core local engines, the 23-language Multilingual engine, and Sonic in 31 languages with its built-in voices.

How does pronunciation quality compare to native speakers?

Quality is strongest in widely spoken languages (English, Spanish, French, German, Japanese, Chinese) and solid across all supported languages. The advanced engine handles native phonetics, tones, and prosody for each of its 30 supported languages.

Can I mix languages within a single script?

Yes. Use speaker tags to assign different languages to different speakers, or generate separate clips per language and arrange them on the timeline. Multi-language projects are a first-class workflow.

Is multilingual generation slower than English-only?

It can be. The fast engine is quickest for English, while the multilingual engine is slower but produces high-quality non-English output. For most projects the difference is negligible.

Which languages support right-to-left text?

Arabic and Hebrew both render right-to-left in the script editor and generate audio with correct reading direction. The text normalization pipeline handles RTL scripts natively.

The Problem

Localization means starting over from scratch

You finished your English content, and now the client wants French, Spanish, and Japanese. Cloud tools make you find a new voice for each language and pay roughly $0.24 to $0.30 per thousand characters in every one, with no guarantee the tone stays consistent. Most creators give up and stay English-only.

The Solution

How multilingual generation works

Same voice, different language. Three steps to localized content.

Write or paste your script

Type in any supported language, or paste translated text. The editor handles right-to-left scripts like Arabic and Hebrew natively.

Pick a voice and language

Select a voice, built-in or cloned, and choose the target language. The voice keeps its tone and personality across languages; a cloned voice keeps the accent of its recording.

Generate locally

Vois Studio generates audio on your machine. No cloud round-trips, no per-language surcharges. Export in any format.

Everything 30 languages enables, explained simply.

30 languages supported

One voice across languages

Cloned voices, designed voices, and the library voices that support Omni speak all 30 Omni languages on Pro. Voice identity carries across languages; a cloned voice keeps the accent of its recording.

Cloned voices go multilingual

Clone a voice from an English sample and use it in Japanese, French, or any Omni-supported language on Pro. The voice identity carries over, along with the accent of the original recording.

Mix languages in one project

Switch languages between speakers or scenes. A French narrator can hand off to a Japanese host without breaking your workflow.

On-device language generation

All supported languages generate on your machine. Source text is not uploaded for TTS. Setup, voice engine downloads, activation, and license checks still use network services.
