speakup: lower default software speech rate

Speech synthesis beginners need a low speech rate, and trained people
want a high speech rate.  A medium speech rate is thus actually not a
good default for neither.  Since trained people will typically know how
to change the rate, better default for a low speech rate, which
beginners can grasp and learn how to increase it afterwards
