From Nath on the emacspeak mailing list:
You can try C-e n which will read you the text until you stop the speech
by pressing C-e s but the cursor will stay at the position it was just
before you run the command. Sorry I don’t know the command which will
cause the cursor to move in the same time the text is read.
