While performing a say-all operation I noticed that Orca is not substituting entries I have in my pronunciation dictionary with their respective alternatives.

The pronunciation dictionary is working fine when reading by word or by line but not during a say-all.

It does not appear to matter whether the say-all mode is set to sentance or line and the problem seems to occur regardless of the application being used.

To reproduce; ensure you have some words in your pronunciation dictionary, now enter some text into either gedit or OO Writer, including some of the words you have pronunciation alternatives for, and attempt to read it using both line navigation and with a say-all.  You should observe that the alternate pronunciations are only being used when navigating the text by line.
