QTextEdit and QLineEdit - Windows Speech Recognition (WSR) Words-Related Commands Not Working

When using Windows Native dictation (Windows Speech Recognition) in
Qt 5.4 examples using QLineEdit and QTextEdit widgets,
dictation works properly, but not word-related commands like:

• Select <word>;
• Correct <word>

There are issues also with sentence-related commands.

There are no such issues with Notepad, WordPad
and Word-2010.

To reproduce:

0. Attatch a microphone.

1. Start a Qt example using QTextEdit or QLineEdit,
i.e. textedit example;

2. Make Setup including Microphone Training, Voice Training, etc
rundll32.exe "%windir%\system32\speech\speechux\SpeechUX.dll",
RunWizard UserEnrollment (Set Up Speech Recognition);

3. Optional - Learn Tutorial
rundll32.exe "%windir%\system32\speech\speechux\SpeechUX.dll",
RunWizard Tutorial (Speech Recognition Tutorial)

4. Run WSR as
Speech Recognition floating window (WSR):

%windir%\speech\common\sapisvr.exe -SpeechUX

5. Dictate some text to textedit example text area;
The text is dictated proprely.

6. Try to use commands like:
Select <word>
Correct <word>

Observe that the commands are not recognized.

7. Repeat dictation with NotePad, WordPad and/or Word.
Observe that the commands used in paragraph 6 are
properly recognized.

The expectation is that
Qt text handling widgets to support WSR commands.
