Converting text to mp3

[Linux for blind general discussion]

Well, thank you. I first ran an apt eventually ran an aptitude, it mentioned 2 
python packages with gtts in their name. But here's what happens when I tried 
converting a text item originally from BookShare.
gtts-cli -o making-of-the-president-1968.txt google.mp3
gtts.tts - WARNING - Unable to get language list: 'NoneType' object is not 
subscriptable
Usage: gtts-cli [OPTIONS] <text>

Error: Unable to find token seed! Did https://translate.google.com change?
Back again live. I hope I had the sequence correct? Also, what about those 
errors? Thanks so much in advance
