#15 Voice recognition using Kaldi

[Kaldi](http://kaldi-asr.org/) is an open-source speech recognition toolkit, which seems to work better than PocketSphinx: * http://suendermann.com/su/pdf/oasis2014.pdf * http://www.mico-project.eu/experiences-from-development-with-open-source-speech-recognition-libraries/ It would be nice if Kaylee could optionally use Kaldi in place of PocketSphinx.
