Saera will continue to be an AI project, and I am hopeful that this will allow for increased functionality (maybe you can eventually 'teach' Saera how to do things she doesn't know how to do).
Changing the official name or changing the name after installation? In the latter case it would be fairly simple, just search and replace "Saera" in a few files.
The beginning of each sentences_<language>.py file contains a line with the espeak command line, of the form Code: espeak_cmdline = "espeak -vCC+f2" , where CC is the two-letter language code. You can also change the 'f' to a 'm' to give Saera a male voice.
espeak_cmdline = "espeak -vCC+f2"
