Dear all,
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.
Got the mod_unimrcp module which is used to recognize the
speech and synthesize the text to voice.
For building the mod_unimrcp modules done the following steps.
Uncomment the mod_unimrcp line in the modules.conf file
in the FreeSWITCH source
Given make mod_unimrcp-install command.
In modules.conf.xml uncomment the <load
modue="mod_unimrcp"/>
Configured the following dial plan
<extension
name="unimrcp">
<condition field="destination_number"
expression="^4922$">
<action application="answer"/>
<action application="set"
data="tts_engine=unimrcp:nuance5-mrcp1"/>
<action application="set" data="tts_voice=awb"/>
<action application="speak" data="This is our Text
to speech on FreeSWITCH"/> -->
<action application="sleep" data="500"/>
</condition>
</extension>
While making the call to 4922 got the following error in the
FreeSWITCH console.

So need to find a solution for that.
