Long scripts and batches of audio
How to handle long scripts and large projects, and download everything in one go.

Long scripts
Each plan has a limit on the characters in one generation. You can compare limits by plan. If your script is over the limit, you'll see a message telling you what your plan allows.
- Fast Speech sends long scripts to the background automatically. They appear in My Speeches when they're ready.
- Text to Speech and Podcast Studio take a little while for any length, and you can leave the page while they run.
Large projects
For an audiobook or a course, split your text into parts:
- Create a folder for the project in My Speeches.
- Generate one chapter or section at a time, using the same voice and settings.
- Give each take a clear title, such as "Chapter 1". Titles can be up to 50 characters.
- Queue the next part. Your plan decides how many takes can wait in the queue at once.
To join the finished parts into one file, use the free Audio Merger.
Download everything
In My Speeches, turn on select mode, tick your speeches and click Download. Several files download together as a single ZIP.
CSV uploads
The dashboard doesn't have a CSV or spreadsheet upload at the moment. To request it, open a ticket and choose Feature idea.
