installing ubuntu 7.4 with speech

[lists at barrettpianos.co.uk]

Hi All

Just joined this list in the hope of some help.

I have the 7.4 ubuntu but am loosing speech when I try to install.

The only instructions I can find relate to previous versions so perhaps this is 
where I am going wrong.
I boot the system and select f5 3 and a couple of returns.  I eventually get 
speech and I land in the orca preferences although the instructions tell me I 
will need to use alt tabb to get there.  

Not sure how I am meant to leave the preferences as the instructions 
mention a "close button".  I am not finding one and tabbing gives me an ok 
or preferences button.  Hitting enter on ok does not seem to have any 
affect.

At this point, continuing with the instructions, I get as far as typing sudo su 
and quitting and restarting orca.  When I type ubiquity I loose speech 
totally.

Just wondering if anyone has any thoughts on what may be happening or 
any instructions that relate to this version?

Also, as I have spent several days at this, if I get some assistance and get 
ubuntu installed, can I reinstate speech after the install and get it to start 
with speech enabelled?

Also, if any one has got this to work, are these speech losses just 
happening around the install or is stability an issue when performing tasks 
e.t.c.

Sorry for the questions but am new at this.

Many thanks
