wow-that worked!  I tried that in the past with another speech and didn't like 
16 kHz sampling but with this mp3 it works fine.  I dropped the
re-sampling spec and the r switch and kept it mono:

lame -m m -b 24 --mp3input original.mp3 compressed.mp3


Thanks for all the help!

To be honest we are expecting --scale to be used with a float number 
(ex: 0.5 or 1.1), but not with a negative number, so there might be a 
parsing problem regarding this in Lame (I'll try to check it).

Regarding your situation, I'd suggest you to try first an encoding 
without specifying the output sampling rate. This will let Lame choose 
it based on the target bitrate and its own knowledge of its compression 
abilities.
As an example, in mono and targetting 24kbps, current Lame version would 
choose to use a sampling rate of 16kHz, which will probably sound better 
than 22kHz.
