Does the Japanese voice read kanji correctly?

Pronunciation can vary, especially for names and technical terms. Try a short passage first; writing an intended reading in kana can reduce ambiguity, but does not guarantee a particular pronunciation.

Can I use these voices for YouTube narration?

Yes. The free tier is for personal, non-commercial evaluation; paid plans include a commercial license for generated audio, so you can publish narration on YouTube and other platforms. Voice identity rights are not transferred.

How long can the Japanese text be?

The editor shows the limit for your current allowance and blocks generation above it. Shorten the script or generate it in sections if you exceed the limit.

Do I need a credit card to use the free tier?

No. The free tier needs only a Google sign-in and a daily check-in; no credit card is required to generate and download audio.

Do I need to install any software?

No. Voxelle runs entirely in the browser — type text, pick a voice, generate, and download the MP3. There is nothing to install.

Which model and voices does it use?

Speech is generated by the Fish Audio s2.1-pro model. The licensed catalog currently lists 82 voices across 13 languages; Voxelle does not train its own voice models.

What is the per-request character limit?

Each generation request is limited to 1,000 characters. The daily check-in allowance is 1,500 characters, resets at 00:00 UTC, and does not roll over.

Yes. Signed-in users can mint an API key under API keys and call the authenticated REST endpoint to generate speech programmatically.

Writing for Japanese speech

Keep Japanese punctuation to guide pauses. For names with several kanji readings, try kana in a short passage and listen before generating the full script.
