William,
No, you cannot train it without sighted help. The training process
presents a story on the screen that you are supposed to read to the
computer. As you read the story, the text changes to green if the
computer recognizes it and to red if the text is not recognized. If
the text is not recognized; you need to reread it to the computer.
Also, there is text that needs to be read to the computer in order to
set microphone level. I don't think either set of text is read by
Voiceover but I'll go back an check.
