One Familiar Voice, Ten Output Languages
Record in any supported reference language. With Pro, the same voice can read English, Chinese, German, Spanish, French, Italian, Japanese, Korean, Portuguese, or Russian.
Available today
Yes. With Pro, one CastReader voice clone can generate TTS in all 10 supported output languages: English, Chinese, German, Spanish, French, Italian, Japanese, Korean, Portuguese, and Russian. Successful audio shares the 120-minute membership-month allowance. The recording language changes only the guided passage; pronunciation and cross-language naturalness can vary with language and recording quality.
Match the familiar voice to the learning task
The clone preserves voice identity across supported languages; it does not replace a native teacher or pronunciation review.
Hear one sentence in another language
Choose an output language, paste a reviewed sentence, generate it, and download the short WAV.

Open an authorized document, choose your owned or shared clone, and keep the text visible while listening.

Try the voice library when a native-style built-in voice is more useful than familiarity for the exercise.
Browse voicesSeparate the voice, the language, and the lesson
Three independent choices make the multilingual workflow easier to understand and review.
Reference language selects the recording prompt
Choose a passage you can read naturally for the 3–30 second recording. It does not restrict later output languages.
Output language guides synthesis
Select one of the 10 supported output languages for the current text-to-speech request, independent of the recording prompt.
You review the actual lesson
Check spelling, names, stress, meaning, accent, and pacing. Generated speech is practice support, not certified pronunciation instruction.
What each language setting changes
Keeping these layers separate avoids the common assumption that a clone only speaks the language used during recording.
| Layer | What it controls | What it does not guarantee |
|---|---|---|
| Recording passage language | The text you read while creating the voice | A permanent language limit |
| Output language | The synthesis mode for the current request | Native accent or perfect pronunciation |
| Text you provide | The exact learning or listening content | Accuracy, translation quality, or age suitability |
| Voice identity | The familiar timbre carried into output | That the real person speaks or endorses the generated words |

Why a familiar voice can help language practice
A familiar voice can lower the emotional distance of a new language. Learners may be more willing to replay a sentence when it sounds like themselves, a parent, or another living person who deliberately shared a Voice Gift. The value is continuity of voice, not a claim that the clone becomes a native speaker.
Cross-language voice cloning separates who the voice resembles from which language the current request speaks. CastReader offers 10 reference passages and the same 10 output-language choices; choosing Chinese for the recording prompt does not prevent a later Spanish or English request.
Generated pronunciation can vary by voice sample, language pair, text, names, and punctuation. Use short tests, compare important material with a trusted dictionary or teacher, and do not treat the audio as authoritative instruction for high-stakes communication.
The generated words are not a statement made or endorsed by the real speaker. Use your own voice or a valid Voice Gift, keep the purpose personal, and disclose AI-generated speech when a listener could otherwise misunderstand its origin.
Multilingual voice-cloning questions
What one clone can do across languages—and what still needs human review.
Do I need to record a new clone for every language?
No. One private clone can be selected for all 10 supported output languages. The recording-language tabs only provide reference passages you can read naturally.
Which output languages are supported?
The current cloned-voice output choices are English, Chinese, German, Spanish, French, Italian, Japanese, Korean, Portuguese, and Russian.
Will the clone have a perfect native accent?
Not necessarily. Cross-language pronunciation and naturalness vary. Review every important result, especially proper names, abbreviations, numbers, tonal distinctions, and unfamiliar words. A built-in voice from the voice library may be a better comparison for some exercises.
Can I download multilingual clips?
Yes. The short voice-cloning generator accepts up to 600 characters and provides WAV download after generation. Longer authorized text can use the document reader and its current bounded workflow.
Can I practice with my partner’s or parent’s voice?
Only with the living voice owner’s active permission. Ask them to create their own clone and a recipient-bound, expiring Voice Gift; do not upload their recordings yourself.
