Dear all, <br><br>          I am in the process of developing IVR. So just planned to convert my application to handle the TTS voice engine which is supported by FreeSWITCH.<br>          Got the mod_unimrcp module which is used to recognize the speech and synthesize the text to voice.<br>
          For building the mod_unimrcp modules done the following steps.<br>               Uncomment the mod_unimrcp line in the modules.conf file in the FreeSWITCH source<br>               Given make mod_unimrcp-install command.<br>
               In modules.conf.xml uncomment the &lt;load modue=&quot;mod_unimrcp&quot;/&gt; <br>               Configured the following dial plan <br>                    &lt;extension name=&quot;unimrcp&quot;&gt;                                                                                       <br>
        &lt;condition field=&quot;destination_number&quot; expression=&quot;^4922$&quot;&gt;                                                 <br><br>                &lt;action application=&quot;answer&quot;/&gt;<br>                &lt;action application=&quot;set&quot; data=&quot;tts_engine=unimrcp:nuance5-mrcp1&quot;/&gt;<br>
                &lt;action application=&quot;set&quot; data=&quot;tts_voice=awb&quot;/&gt;<br>                &lt;action application=&quot;speak&quot; data=&quot;This is our Text to speech on FreeSWITCH&quot;/&gt;  --&gt;<br>
                &lt;action application=&quot;sleep&quot; data=&quot;500&quot;/&gt;<br>        &lt;/condition&gt;                                                                                               <br>  &lt;/extension&gt;<br>
<br>     While making the call to 4922 got the following error in the FreeSWITCH console.<br><br>       <br clear="all"><pre width="100">[INFO] mod_dialplan_xml.c:418 Processing thangappan-&gt;4922 in context default<br>         [NOTICE] mod_dptools.c:717 Channel [sofia/internal/<a href="mailto:1012@192.168.1.222">1012@192.168.1.222</a>] has been answered<br>
