speech, it would signal an event so we would stop playing the prompt.<u></u><u></u></span></p>

<p class="MsoNormal">Hello,<u></u><u></u></p>
<div>
<p class="MsoNormal">you are correct. Very large grammars are only feasible with UniMRCP, and there is recognition quality to keep in mind too, which is far better on Nuance or Lumenvox than you can get with Pocketsphinx.<u></u><u></u></p>

<p class="MsoNormal"><u></u> <u></u></p>

<p class="MsoNormal">We use Lumenvox with UniMRCP for most ASR use cases, but with 100,000 options it might very well be the only solution for you.<u></u><u></u></p>
