Hi Pete,<br>
<br>
I&#39;m afraid that the answer&#39;s still the same: use a human.  Here&#39;s an<br>
article describing the state of the art:<br>
<a href="http://www.theregister.co.uk/2009/08/05/spinvox_demo_day/" target="_blank">http://www.theregister.co.uk/2009/08/05/spinvox_demo_day/</a><br>
- the links to previous stories at the bottom provide good background.<br>
<br>

<div><div></div><div><br>
&gt; I apologize, I should have been more clear.  We will be using humans<br>
&gt; to scan the translated results.  But we are looking for a system to<br>
&gt; perform the &quot;first pass&quot; on the audio to hopefully help the human type<br>
&gt; less.<br>
&gt;<br>
&gt; Although the question has been raised if it&#39;s faster to have a human<br>
&gt; just transcribe the whole thing, or fix up what the computer spit out.<br>
&gt; If you have any insights on this, that would be great.<br>

&gt;         Good evening Pete,<br>
&gt;<br>
&gt;         The only way to do this is, I&#39;m afraid, to use a human. We use<br>
&gt;         Amazon&#39;s<br>
&gt;         Mechanical Turk to good effect.<br>
&gt;<br>
&gt;         Cheers --<br>
&gt;<br>
&gt;         Dave<br>
&gt;<br>
&gt;         &gt; Good morning all,<br>
&gt;         &gt;<br>
&gt;         &gt; I realize this is slightly off the FS topic, but I am<br>
&gt;         wondering if<br>
&gt;         &gt; anyone out there has experience with software packages<br>
&gt;         designed for<br>
&gt;         &gt; the transcription of voicemails to text. I&#39;ve used<br>
&gt;         pocketsphinx with<br>
&gt;         &gt; FS to handle IVR menus, but now have the task of figuring<br>
&gt;         out how to<br>
&gt;         &gt; convert recorded phone conversations (voicemails mostly) to<br>
&gt;         text.<br>
&gt;         &gt;<br>
&gt;         &gt; This does not have to be a real-time process, I can store<br>
&gt;         the audio<br>
&gt;         &gt; files and process them over time. This would need to be a<br>
&gt;         software<br>
&gt;         &gt; (preferable open source) solution. ASPs like VoiceCloud<br>
&gt;         would not<br>
&gt;         &gt; work for this application.<br>
&gt;         &gt;<br>
&gt;         &gt; Thanks for any help<br>
&gt;         &gt; -pete<br>
