The default port for esd is 5001.  This can changed via the -port option
to esd (e.g. esd -port 5002).  The ESPEAKER env. variable may take three forms:

1)  machine[.wherever.feh], where esd is running on the default port of machine 
2):NNNN, where NNNN is the esd port on the localhost 
3)  machine[.wherever.feh]:NNNN, where NNNN is the esd port on machine
