This section details on the original issue you should resolve

<issue_title>.say() method not processing more than 1 call</issue_title>
<issue_description>Once the .say() method is called more than once it only finishes the first call then ignores the rest of the calls
How To Reproduce:

import pyttsx3
engine = pyttsx3.init()
engine.say("gig")
engine.runAndWait()
engine.say("gig")

Expected Output:
One reading of the word "gig"
Then runs the .runAndWait() method
And another reading of the word "gig"
Actual Output:
One reading of the word "gig"
Then runs the .runAndWait() method
And then ends the program

And the following code also has this bug:

import pyttsx3
engine = pyttsx3.init()
engine.say("gig")
engine.say("gig")
engine.runAndWait()

Expected Output:
Two readings of the word "gig"
Actual Output:
One reading of the word "gig"
Then runs the .runAndWait() method
And ends

System conditions:
python 3.13.9
pyttsx3:Version: 2.99
Microsoft Windows [Version 10.0.19045.6691]
Vs code version 1.107
Git bash as the terminal in vs code
