I tried CMU&#x27;s Sphinx without training it first.<p><pre><code>  $ ffmpeg -i changelog-201.mp3 -acodec pcm_s16le -ac 1 -ar 16000 out.wav
  $ pocketsphinx_continuous -infile &#x2F;tmp&#x2F;out.wav &gt; &#x2F;tmp&#x2F;transcript.txt
</code></pre>
The first line of output read<p><pre><code>    i&#x27;m richard have been you&#x27;re listening to the change log and have it type collector who won this bit she&#x27;s long time they&#x27;re both have people get this this episode two zero and the invaders now i&#x27;ve got to purchase this creature
</code></pre>
If anyone knows how to train Sphinx to understand technospeak, I would love to know also.
