<div>I don't pretend to fully understand the build system, but the makefile seems to be trying to go to libs/sphinxbase for files, when that directory doesn't exist.

The mod_pocketsphinx wiki page says that 16Khz is a supported sampling rate, so I'm guessing that there is a special reason why Speex doesn't work, or else that this is a bug.</div>
