[Freeswitch-users] Freeswitch 1.6 with Nuance Vocalizer 6.2.3 - "Client connection refused"

[Hector Geraldino]

IIRC it was Vocalizer for Network 5.0 and some other Nuance Speech Server or something like that.

I think requests were being handled by an NSServer process that was started on a different directory. Sorry I cannot be more helpful, but I no longer have access to that environment.

Hi Hector,

Yes, I double checked that the nuance-server is listening on 9200 port. the above [0] [1] [2] [3] messages I can see on the nuance-server side.

On freeswitch side I can see:

I suspect that either something might have been "updated" in Vocalizer and won't recognize what Freeswitch sends it anymore or I am doing something wrong in the extension config:
        <extension name="tts">
                <condition field="destination_number" expression="^tts$">
                        <action application="sleep" data="2000"/>
                        <action application="set" data="default_language=en-GB"/>
                        <action application="set" data="tts_engine=unimrcp:nuance6-mrcp2"/>
                        <action application="set" data="tts_voice=Serena"/>
                        <action application="speak" data="Speak to me."/>
                        <action application="hangup"/>
                </condition>
        </extension>


Can you tell me the Freeswitch and Vocalizer versions it worked for you?

Thank you,
Stefan

Is the Vocalizer for Network/NSS listening on that port?  Can you nmap/telnet to that IP address on port 9200?

I had no issues with using Nuance’s Vocalizer with MRCP using the mod_unimrcp module.

Hi,

I unsuccessfully tried to do TTS on Freeswitch using mod_unimrcp (with specific nuance profile), by connecting to nuance-server.

I started the Nuance server in mrcp mode: [0]

For MRCP v1 I get [1].

For MRCP v2 (using TCP) I get [2].

For nuance nvscmdline I get [3].

The FS unimrcp profiles I used are [4] for v1 and [5] for v2.

Am I missing something here?!
Have anyone tried this lately? Is Freeswitch 1.6 mod_unimrcp working with latest Nuance?

Thank you,
Stefan
