You don't need sighted help compiling a new kernel. It can all be done using gnome terminal. You can get the latest kernel source from kernel.org. There might already be a ubuntu package with speakup in the kernel for all I know. If Orca is working correctly I'm not sure what the big advantage of using speakup is anyway, but it is nice to have around. So if you really must build that kernel, the best way is to have someone talk you through it. Kinda makes me tired just thinking about it. Too early for a nap though!
