Kindly I ask your attention.
There are a lot of free programs that can do that, without copying into the program itself. That's bad software you use.
If you are using Firefox, you can download an add-on that can only read the text lines you select in Firefox.
Start your browser, search with different search engines and use different phrases.
Microsoft Text to Speech
Microsoft Text to Speech driver

Free Text to Speech
Best Text to Speech software
Best free Text to Speech software
And so on.
There you will find a lot of links to go for.
When you found the answer you seek, let us known how and/or what.
Hopefully I let you known enough and that you will find the answers you seek!
Good luck and have fun doing it!
Best Regards,
