How to record text to speech from Pages to an audio file

Your profile still shows that you are on macOS El Capitan (10.11). Is that the current operating system?

An Automator solution does not give you access to any Siri voices, and a Monterey or later Shortcut solution gives you access to three different Siri voices when selecting text from Pages or Keynote. Haven't tried it with Keynote though.

Here is a Shortcut solution that takes selected text in Pages v13.2 on macOS 14.4 and outputs a 48Khz .mra audio file to the Desktop by using a ^⌘V keyboard shortcut.

The iCloud link that you can open in Shortcuts is here.

I have revised the above Shortcut so that if a Pages document is open, it will get the basename of the document, append a ".m4a" file extension to it, and when the shortcut has saved the text to voice file on the Desktop, that voice file is then renamed to the Pages document name (e.g. crazy.m4a).

The new link is here.
