Voices marked free need no payment. Over a long book, the voice decides whether you keep listening more than any feature list does.

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.
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.

BROWSE BY VOICE LANGUAGE
Start with the language, then compare voices
Each guide keeps one language's real samples, quality status, pronunciation checks, and long-form reading guidance together. New voices flow in from the live catalog without creating a new SEO page for every voice.

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 workflowA 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 283 evaluated entries, with 283 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.
What is the difference between Free and Pro voices?
Both are shown in this catalog with the same real samples, and every voice is labelled with its tier. Free voices are available without an account; Pro raises daily listening limits and unlocks the larger premium collection. Current limits and prices are on the pricing page.
Which languages are production-ready?
The live catalog currently includes 9 languages. English and Mandarin are GA. Japanese, Spanish, French, German, 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.
