Catalog version and availability can change as voices pass quality review. GA means the language workflow is production-ready; Beta and Lab languages are not presented as equivalent to GA. Private cloned voices never appear in this public catalog.
Find a voice for the reading job
Choose what you need to read and compare a short list first. These suggestions use the catalog's reviewed descriptions and best-for labels; they are a starting point, not a claim that one voice suits everyone.
Source language
Voices to preview first
Listen to a full sample before deciding. Comfort over a long session matters more than a dramatic opening sentence.

VOICE SHOULD MATCH THE READING JOB
Choose for the content, not just the first sentence
A five-second demo can sound impressive. A useful reading voice must stay clear and comfortable across chapters, formulas, arguments, and long sessions.
Books and long-form reading
Use measured, grounded voices for chapters and long listening sessions, with progress, highlighting, and background playback preserved.
See the reading workflowPapers and study material
Choose clear voices that make terminology easier to follow, then switch to Read & Explain when pronunciation alone is not enough.
See the reading workflowPDFs, documents, and webpages
Keep the selected voice across PDFs, EPUBs, DOCX files, pasted text, and supported browser pages instead of exporting disconnected clips.
See the reading workflowReading in another language
Use a voice that matches the source language, while CastReader can explain difficult passages in a language you understand.
See the reading workflowYOUR VOICE, KEPT PRIVATE
Clone your own voice for personal reading
In supported iOS and Android builds, a signed-in Pro member can create a private reading voice from a short, clean reference recording. The result stays in the user's Created tab and can read supported content without publishing the clone to a public marketplace.
Consent and ownership are part of the product
Creation requires an authenticated account, an explicit owner-consent confirmation, and an active Pro entitlement. Reference audio is encrypted at rest. A user can delete the voice, and private clones are never indexed as public SEO pages.
- 1
Sign in and confirm Pro
Voice cloning is tied to an authenticated account rather than an anonymous device.
- 2
Record one clear speaker
Use a clean 3–30 second WAV or FLAC reference with no music, echo, or additional speakers.
- 3
Confirm ownership and consent
Create a voice only when you own the voice or have the required rights and explicit consent.
- 4
Preview, select, or delete
The private clone appears under Created voices. Preview it, use it for reading, or remove it from the account.
- 5
Respect the creation limit
One successful clone creation is allowed per user in a rolling 24-hour period.
A reading voice library, not a voiceover studio
CastReader does not ask you to generate a clip, download it, and manually find your place again. The voice runs inside a reading workflow with the original text, synchronized highlighting, auto-scroll, progress, background playback, and explanations for difficult passages.
Voice generators produce audio. CastReader uses a voice to help you finish and understand what you already need to read.
For advertising, dubbing, podcast production, or a public voice marketplace, use a dedicated creator platform. CastReader is designed for personal reading across books, documents, and supported pages.
Questions about CastReader voices
How many voices does CastReader have?
The live catalog currently contains 149 evaluated entries, with 149 voices selectable and previewable in the public reading catalog. Availability changes as voices pass quality review. Visit the download center for supported clients.
Can I preview a voice before selecting it?
Yes. Every voice shown in this public catalog has a real audio sample. The mobile voice browser also supports search, filters, favorites, recent voices, and recommended voices.
Can CastReader clone my voice?
Private voice cloning is available to authenticated Pro members in supported iOS and Android builds. It requires owner consent and a clean reference recording. Check the official mobile downloads for current availability.
Can I clone a celebrity or another person's voice?
Do not create a clone without the required ownership, rights, and explicit consent. CastReader is designed for consent-based personal reading voices, not impersonation.
Does CastReader publish cloned voices?
No. Personal cloned voices remain private to the authenticated account and are not added to the public catalog or indexed as public pages. See the privacy policy for data handling details.
Which languages are production-ready?
The live catalog currently includes 8 languages. English and Mandarin are GA. Japanese, Spanish, French, Brazilian Portuguese, Italian, and Hindi are Beta or Lab workflows, so availability and synchronization quality vary. The language selector above shows current status and voice count directly from the catalog.
What makes a good voice for books or PDFs?
Choose for sustained clarity rather than a dramatic first sentence. Measured and grounded voices often work well for books; clear, balanced voices suit papers and documents. Use Read & Explain when the difficulty is meaning rather than pronunciation.
Does changing the voice lose my reading progress?
No. Voice selection is part of the CastReader reading workflow, alongside highlighting, auto-scroll, background playback, and resume progress. Explore the mobile Kindle reading experience.
Choose the voice where you actually read
Use the same reading workflow on your phone or supported browser pages. Voice availability can vary by platform and app version.
