Subject: [PATCH] Fix console output issue in `tts` function of `synthesizer`
 class

Fix Console Printing Issue in synthesizer Class

This update addresses an issue with the tts function in the synthesizer class where console output, including the array of split sentences, processing time, and real-time factor, was being printed during execution. This was causing unwanted console output when the synthesizer function is run in a thread.

Changes Made:
Added criteria SuppresPrintStatements type boolen to suppress console output generated by the tts function.

Ensured that print statements are only triggered when explicitly required, preventing cluttered console output during threaded execution.
This modification improves the usability of the synthesizer class when integrated into threaded applications and enhances the overall user experience by minimizing unnecessary console output.
