For readers who access eBook content through audio, this page lists browser-based text-to-speech (TTS) tools that work alongside eBook readers, with a summary of each tool's free and paid options.

About text-to-speech tools

Text-to-speech tools read on-screen text aloud. The audio features built into many academic eBook platforms are fairly basic, so some readers use a separate browser-based tool instead. The options below run in the browser alongside eBook readers and do not require a download.

This page is provided for reference only. The Library does not endorse any particular tool; the summaries below are meant to help readers compare options and decide what may fit their needs.

For reference: CastReader and Read Aloud are listed as completely free with no time limits.

Will these work with Fuller eBooks?

They read the text shown on the page, so they generally work alongside online eBook readers. Some platforms limit text selection or display pages as images, which can affect how well a tool reads them — it's worth testing on the specific title you need.

Are these supported by the Library?

These are third-party tools, listed here as helpful options rather than officially supported services. If you'd like help accessing eBooks or navigating databases, please contact us at library@fuller.edu.

How much do the paid options cost?

Pricing changes often and can vary by region, so this page links to each tool's official pricing page rather than listing amounts. Follow the link in the table for the most current details.
