<p class="MsoNormal">I noticed that there is no grammar model “wsj1” inside /usr/local/freeswitch/grammar/model<o:p></o:p></p>
<p class="MsoNormal">Also I cannot find wsj1 anywhere from the src or freeswitch files online. Does anyone have a tar.gz version of this? So at least I can get past this issue.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Then I decided to follow the Lua directory example: <a href="https://freeswitch.org/confluence/display/FREESWITCH/Lua+ASR+TTS+Directory+Example">

<p class="MsoNormal">==========================================<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Next we create our dictionary and language model file. Change your directory to /usr/local/freeswitch/grammar and create a file called directory.sent<o:p></o:p></p>
<p class="MsoNormal">We are using Matthew Williams and Joe Smith as our examples.<o:p></o:p></p>
<p class="MsoNormal"><s> MATTHEW_WILLIAMS </s><o:p></o:p></p>
<p class="MsoNormal"><s> MATT_WILLIAMS </s><o:p></o:p></p>
<p class="MsoNormal"><s> JOSEPH_SMITH </s><o:p></o:p></p>
<p class="MsoNormal"><s> JOE_SMITH </s><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Type make in the /usr/local/freeswitch/grammar directory.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This should give you the following files.<o:p></o:p></p>
<p class="MsoNormal">ls -la directory<o:p></o:p></p>
<p class="MsoNormal">-rw-r--r-- 1 root root 82 2008-08-13 10:59 directory.dic<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This does not work since the “make” does not work here!<o:p></o:p></p>
<p class="MsoNormal"><o:p></o:p></p>
<p class="MsoNormal">Any ideas?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So far not much luck. I understand that pocketsphinx is not really a production product, however my client would like to make use of it for internal testing only.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any assistance would be great.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
