Google SS: Failed to Create Session TTS-4

[Wilmar Pérez]

Hi all,

I am just testing unimrcp with Google SS. We have the following:

• Freeswitch 1.10.1 (64bit)
• Admin interface: Fusion PBX 4.5.9. I am not sure this makes much difference but one never knows.

We are just trying to test the out of the box example. 

<action application="speak" data="unimrcp:uni2|en-US-Wavenet-A|Welcome to FreeSWITCH"/>

But we keep getting the following:

2019-10-19 15:48:39.443720 [WARNING] mrcp_client_session.c:1269 (TTS-4) Failed to Create Session TTS-4 <new> [2]

Followed by:

2019-10-19 15:48:39.443720 [ERR] mod_unimrcp.c:1920 (TTS-4) SYNTHESIZER channel error!

2019-10-19 15:48:39.443720 [ERR] switch_ivr_play_say.c:3006 Invalid TTS module unimrcp:unimrcpv2[en-US-Wavenet-A]!

So, we get it, the module is invalid. Then, what do we need to fix? This is our unimrcp_conf.xml:

--------------------------------------------------------------------------------------------------------------------------------

<configuration name="unimrcp.conf" description="UniMRCP Client">

  <settings>

    <!-- UniMRCP profile to use for TTS -->

    <param name="default-tts-profile" value="unimrcpv2"/>

    <!-- UniMRCP profile to use for ASR -->

    <param name="default-asr-profile" value="unimrcpv2"/>

    <!-- UniMRCP logging level to appear in freeswitch.log.  Options are:

  </settings>

  <profiles>

    <X-PRE-PROCESS cmd="include" data="../mrcp_profiles/*.xml"/>

  </profiles>

</configuration>

--------------------------------------------------------------------------------------------------------------------------------

And the profile: (actual IPs are different)

Can anyone please give us a hint into what we can look into?

Hi Wilmar,

The following log statement

Thanks very much Arsen. This has put me in the right track, In fact, our freeswitch installation has a problem. We are fixing it today to test it.
