Sapi Tts Not Enabled

[iTime]

Hi,

 

I am creating this new ticket to convey the TTS issue only from the existing ticket: (here)

 

you mentioned:

Regarding TTS:

 

ktTel trace shows:

 

020 182804.442 4740 WARN CreateTTSPort returned NULL. SAPI TTS not enabled.

 

You may want to re-install AT&T SAPI tools.

 

If you continue to have issues with TTS please start a new topic on TTS issue.

 

I removed and reinstalled ATT natural (audrey) voice. The engine we use however, is Microsft SAPI: we only bought the voice of ATT Audrey.

 

I installed MS Speech SDK 5.1 and realized that SDK 5.3 is loaded on Windows 2008 64 bit then uninstalled it.

Would this be a problem? The server we use is VM ware, and I hope virtual environment does not cause this TTS problem...

 

Please let me know what else I need to try. (I tried to download Speech 5.3 from Microsoft, but it is not available.)

 

Thanks.

This IVR server is located in a hosting service environment, and I got the following reply from one of the support teams for my question, if we can install/enable Microsoft speech (SAPI engine) on this VMWare environment:

 

After some investigation with our Virtualization team they advised the only way we might be able to install this plugin would be to add a soundcard to the hypervisor then assign it as a resource to the VM as this will require a soundcard. You will be required to provide the sound card. I would advise trying to find one that's hypervisor compatible (assuming such a card exists). Bare in mind this is not something we can guarantee will work.

 

Is this what I need? If so, could you list "compatible" sound card we could install?

 

Thanks.

[SupportTeam]

Sound card is required for correct SAPI operation.

 

From http://www.voiceguide.com/vghelp/source/html/config_tts.htm :

SAPI expects a sound card to be installed on the system. Please ensure a sound card is installed on the system and its drivers configured prior to installing Microsoft SAPI.

 

We do not keep a list of sound cards that can be used. You would need to contact sound card manufacturers to check suitability for your environment.

Any comment on this issue?

 

I tried to find any similar topics in the forum, but there was not anything...

I hope I am not the only one who tries to use HMP + VG with TTS on VMWare with SAPI engine issue...

[SupportTeam]

Most systems do not use VmWare. Only HMP based systems can be used under VMware, but still more people use HMP without WMware then with.

 

Doing a Google search for "vmware compatible sound cards" or similar should bring up a list of relevant results.

 

A good first choice could be the Sound Blaster card.

[iTime]

Does it mean that I need to install a sound card on a machine that hosts the hypervisor environment?

I would like to confirm with you that TTS can be used on a virtual environment (VMWare especially) if a sound card is installed on its physical machine. This is a virtual environment we are using.

 

Thanks.

[SupportTeam]

We've had it reported that this resolved TTS issues in other installations, but not able to confirm whether their virtualisation environment was the same as yours.

We are getting a new sound card and will try to see if that resolves it. I will keep you posted as well.

We have managed to install a sound card on the hosting machine and ported audio resource to this VMWare.

I can now play some demo/sample tools from speech SDK 5.1, such as "VBTTSApplication", or "SampleTTSDHTML" and even could create "wav" file by clicking "save to wav" button.

 

However, I still get this "SAPI not enabled" error on my VG7.3.3_130412.exe (that was provided via the following issue, "White Paper Or Instructions For Sip Integration".)

 

Here is a funny thing: While I was trying any possible trial and error processes to fix this, I removed this custom version of VG and re-installed the release version, VG7.3.2 then I saw it generate "ktTts.txt" file, which I believe SAPI engine was successfully initiated on this version.

I could not try to call with this version and see if TTS plays becase it hung up on me (due to the HMP-related error you have fixed via the 7.3.3), but I believe TTS should work with this version as it created the ktTTs log file.

 

Would you take a look at this issue and see if the 7.3.3 version can also work with SAPI engine?

 

I attach the VG logs created by those two versions of VG just in case.

 

Thanks a lot.

This is one more testing related with the issue posted right above:

 

I tried to install "VG7.3.3_130412" on my local test bed (Windows 7, Dialogic D/4PCI, NO virtual environment) to see if this version of VG affects only HMP driver, and found out it did not create ktTts log either on this environment. So, I guess this TTS issue is somewhat related with this version of VG.

 

Now the problem for my test server is that I uninstalled this "VG7.3.3_130412" and re-installed the previous version of VG (7.3.2), but the server hangs up at the first module upon receiving a call.

I noticied that the VBscript raises a [null] error on

Set vg = CreateObject("vgServices.CommandLink")

(Please see attached log and screen shot)

 

Please also help me get my test server back to life..

 

Thanks.

I think we have found the cause of TTS module not loading.

Please stop VG service and then install this version:

If you still have issues with the module in your script not working then please start a new topic about this, as this is unrelated to TTS module not loading issue.
