The old way is slow and expensive

Manual translation, hired voice actors, days of waiting. Creators and teams lose time and money on every single video.

Skip the old workflow

Renting voice actors for every new script?

Inconsistent voice across your video series?

Losing your creator identity when you outsource?

Cloning tools that need hours of training audio?

A few clicks, that is all.

02

AI clones your voice

A few clicks, that is all.

03

Type text in any language

A few clicks, that is all.

04

Generate speech in your voice

A few clicks, that is all.

I narrate my own audiobooks in English, but my Japanese publisher wanted a localized version for the Tokyo market. Hiring a Tokyo voice actor would've cost $3,000+ and taken six weeks of back-and-forth. Instead, I recorded 10 minutes of my speaking voice, uploaded it, and got back an MP3 of me speaking fluent Japanese—same vocal tone, same pacing, just in the target language. The whole process took under an hour. My Japanese listeners now hear *my* voice, not a stranger's.

FAQ

Common questions

Will my cloned Japanese voice still sound like me, or like a generic narrator?+

It keeps your specific vocal fingerprint—pitch, rhythm, even your habitual pauses. I compared my English raw recording side-by-side with the Japanese output; the 'voiceprint' match was unmistakable.

Do I need to speak Japanese myself to clone my voice for Japanese audiobooks?+

Not at all. I don't speak Japanese beyond basic greetings. The system handles the language conversion; you just provide a clean sample of your English voice speaking naturally.

What audio format do I get, and does it work with Audible Japan's requirements?+

You receive standard MP3 files. My Japanese publisher accepted them directly for distribution, including Audible Japan. No additional conversion needed.

How accurate is the AI result?+

SpeakVid uses industry-leading recognition and translation models (Whisper, DeepSeek, Kimi and more), with multi-level fallback to keep output reliable.

How long does it take to clone my voice for japanese audiobooks?+

Most tasks finish in minutes. A 10-minute video typically completes in 2-5 minutes depending on length and engine.
