I have tried using Nsss and pyttsx3 on mac but it says there is an error:
NameError: name ‘objc’ is not defined. Did you mean: ‘object’?

If you look inside a ‘speak’ function I am using both nsss and pyttsx3, when I use nsss it works fine for me, but not with the other. I don’t know what to do, is it supposed to work or change something to be able to run the program using pyttsx3 on mac?
