What is a good way to convert mp3 files to speex files? I'll favor answers that give an easy solution for converting multiple files at a time and/or maintain good quality for spoken audio. Though any solution will be appreciated since I haven't found even a difficult way that works.

Example for processing all mp3 files in current folder to speex using wide band (input rate converted to 16KHz with best SRC available - SoX):

for f in *.mp3 ; do sox "$f" -r 16k -t wav - | speexenc -w - "${f%.*}.speex" ; done

Depending on preferences change speex option and/or SoX rate converter to appropriate setting. For spoken audio example wide band should be fine
