I used Audacity for the editing, recording the speech in a few passes
then joining it into one long data stream. I tried clipping
automatically with wavsilence, but it although it did a fairly good job
of the split, I'd have had to clip manually anyway, so I returned to
Audacity and selected and exported the WAV files from the initial stream.

It's a fair amount of work, but being partially sighted, I was very
pleased to see Rockbox making the JB blind accessible, and I wanted to
add something to that effort. If someone has a soundcard with a low
noise mic line that they'd be willing to donate, I'd be willing to do it
again - it's a few hours work, but as you say, it's a nice luxury.

I tried Audacity's built in noise removal facilities, but they made my
voice sound really weird and tinny. If anyone knows of a free tool with
better noise removal, please let me know. Of course the correct
solution is to get a better recording in the first place.

It seemed bearable to me listening on the PC, but people have different
standards, and it probably sounds different on the JB itself.

The patch is at

It's a bit quick and dirty, but it works with the lang files as distributed.

You're welcome.
