An approach:

train the system on a small amount of manually
transcribed speech (.wav and .lab) and then use it to transcribe a
larger amount of untranscribe speech (only with .wav).  If the
confidence level is high enough, then add into the
trainning data and the process will be run iteratively until all the
untranscribe speech is added to the trainning data.
