synthesis is impossible because the rockbox has access to the headphones
only through the mp3 hardware codec.
To avoid lag, these pieces of pre recorded sounds must be stored in ram.
Again, the thing is not so simple. I have no experience in the rockbox, but
I imagine that when rockbox wants to play a sound, it has to do lot of
1) stop current song (remember where it is)
2) reprogram the codec settings for the sound to be played
3) play the sound
4) reprogram the codec settings back to the song
5) refetch song mp3
The lag should be tolerable if everything is in memory.

One solution I suggest is to record only a small number of short sounds, for
the memory footprint to be minimal.
What about pre recorded numbers or beeps telling where you are in the menu
hierarchy, and then you can navigate with the documentation?

for example, "beep 1" tells you that you are on the root menu over choice
number 1.
"beep 3 5" tells you that you are in menu 3 and submenu or choice number 5
"beep" tells you that you are out of config menu

Of course you have to read your doc to navigate...
