Summary of the issue:

In NVDA 2019.3 some SAPI4 synthesizers like Syntalk don't work properly. as the final index is not get by Screenreader.
As a result, when focusing some lists or explorer windows, the highlighted element is not reported. Also spelling does not work.

Description of how this pull request fixes the issue:

As the sequence is closed by some synthesizers just after reaching the last string in queue, we simply add 1ms break after all sequences sent to SAPI4 voice.

Testing performed:

The last index in speech sequence is sent to NVDA again. When focusing the desktop or using tab to navigate across elements, all items are now reported properly.
This was ested both on Windows 10 and Windows 7 and confirmed by some users from Poland.

Known issues with pull request:

None issues found.
The drawback is that spelling may prove to slow down a bit after implementing this solution.

Change log entry:

Bug fixes
SAPI4 voices should now properly report once the speak is completed

Added 1ms break after SAPI4 speech sequence as some synthesizers like Syntalk are completing the sequence just after last text, ignoring additional indexing

A similar issue exists at issue 10901.

Except that has to do with SAPI5.
