pyttsx3 audio output wav file is not saved

Question

Now I tried to save the audio output into wav files (mp3 file cannot play, no sound), but it play the audio but does not save audio files at all. Also this program eventually halted when all files under TTBOD folder are exhausted. I can see the mac wheel spinning when I go to the latest popup window. I suspect the halting might be the reason that mp3 files cannot be save since I can save the .wav file when I only use one document and don't go through all documents. But I am not sure. Can anyone help me to debug the codes? Thank you.
