gTTS slow on generating file
Hi,
I've used this library for almost 2 years. I runt a python script on a RPi3 and now when It start generating mp3 file from TTS conversion it locks for aroung 1 minute or more and no output file is generated. This behaviour seems to be randomic. Is there any issue between gTTS and Google Translation system?
