<p>Hi Jerry,</p>
<p>This is the OOV utterance problem — here is the relevant Pocketsphinx FAQ entry:</p>

<p>Thank you!<br />
I will see that. ^_^</p>
<p>hi!</p>
<p>I saw the doc .But It’s difficult to understood for this: <strong>“However, since a phone loop should give us better rejection than confidence scores, I propose that we implement a phone loop in the FlatLinguist as a first attempt. It should be fairly easy to expand the unknown word <unk> into an all-phone self-looping network. As a starter, context-independent phones will be used, since context-dependency was shown to not matter in this case. If a result contains the <unk> word, the utterance can possibly be out-of-grammar. We leave it to the application developer to determine that. “.</strong></p>
<p>1.what the “phone loop” mean?</p>
<p>2.how to use “<strong><unk></strong>“? Is there a sampleCode for Implementation Details?</p>
<p>thx a lot~</p>

<p>Hi Jerry,</p>
<p>Since these are questions about the implementation of Pocketsphinx it would be better to ask them at the CMU Sphinx site.</p>

<p>Updated: you can now handle out of vocabulary rejection using Politepix’s <a href="/shop/rejectodemo" rel="nofollow">Rejecto</a> plugin for OpenEars.</p>
