I hop around so many apps -- I thought I'd better come up with a better way to do TTS(at least for me).
I created an applet that I can access from my system tray -- whatever text may be highlighted in another app --if I right-click this from system tray and 'play' the text is read back via SAPI.
If you'd like to try --download and follow these instructions:
1) Download TTSAnyAppTray_SE.exe to Desktop or Documents folder:
2) Run TTSAnyAppTray_SE.exe to extract the software
(must be done as Administrator). This creates a folder
called MyItzyBits under same folder as downloaded to in step 1.
3) Double click ..\MyItzyBits\TTSAnyAppTray.exe
4) Highlight some text in most any application
5) Click the '►' icon in your system tray and 'Play' from that
TTSAnyAppTray.exe has additional options:
ReadBrackets ~ check to read numeric footnote, e.g.,  - default behavior is to not read these type items.
ReadParens ~ check to read numerics found inside parens, e.g., Robert Louis Stevenson(1850-1898) default behavior is to not read these type items.
Phonetics ~ click to open a window which stores ~ saves a list of phonetics "swaps", for example "WAR I=WAR ONE, etc.
ProcessQuit.exe, TTSAnyAppTray.exe, TTSAnyApp.exe

Of course, a truly thinner TTS would be a Kindle. But, on our budget that may be a while. Meanwhile...
The phonetics are now "saveable". Try changing "(default)" to a specific name and then pressing OK. If you then click the '...' -- you bring that file up and edit your own set of phonetics. If you want to have multiple copies -- save as a different name.
Note: If you want to download additional~updated phonetics files -- download to same directory as to which you downloaded software and extracted (step 2)
