Screencast with VoiceOver

Here’s a quick how-to on recording your Mac desktop while using the VoiceOver screen reader. With this setup you’ll be able to capture both video and internal audio at the same time, and hear the audio output while recording.

Setup

For this setup we’ll be on OS X El Capitan and use QuickTime to capture the video and audio. The only extra thing required is the iShowU Audio Capture driver.

Steps

1. Install the iShowU Audio Capture driver.
2. Go to Applications/Utilities and launch Audio MIDI Setup.
3. Create a new "Multi-Output Device" by clicking the bottom left + icon.
4. Under the "Use" column, check the Built-in Output and the iShowU Audio Capture checkboxes.
5. Set the Master Device to your default audio output source so you can hear the audio as you record.
6. Go to Preferences > Sound.
7. Set the Output to Multi-Output Device.
8. Set the Input to iShowU Audio Capture.
9. Open Quicktime and go to File > New Screen Recording.
10. Click the arrow next to the red recording button and select iShowU Audio Capture.
11. Click record.

Profit

You can now record VoiceOver audio along with desktop video to capture those accessibility demos or issues and impress your friends!

You also need to set the output of VoiceOver to 'Multi-Output Device' in the VoiceOver Utility (Application->Utilities->VoiceOver Utility and choose the 'Sound' tab)

And restart VoiceOver - CMD + F5 toggle should do it.
