You can add a pause after the letter ‘C’. Text Speaker allows you to enter a customized pause length within your text. Put the cursor at the position where you want to add a pause, then click on the "Edit" menu >> Insert Pause. Use the predefined ‘0.25 seconds’ pause duration.

Now, Text Speaker will take a pause after reading letter ‘C’ and the instructions will be much clearer.

You can also add a comma after the letter ‘C’. The default timing after a comma is half a second.
