Guest u4910 Report post Posted 10/22/2019 01:22 PM I am trying to figure out what TTS engines are installed. The doc says to look in the ktTts trace log file. That file seems to be binary. Should it be readable as text? The list of TTS engine names that are installed on the system can be obtained from the VoiceGuide ktTts trace log file. At the beginning of the trace file there will be a section that lists all SAPI engines installed on the system. That section looks something like this: 124244.953 2812 tts voice 0 : Microsoft Mary 124244.953 2812 tts voice 1 : Microsoft Mike 124244.953 2812 tts voice 2 : Microsoft Sam 124244.953 2812 tts voice 3 : Cepstral Allison-8kHz 124244.953 2812 tts voice 4 : Sample TTS Voice The name of the engine is listed after the "tts voice X : " tag. The example listing above shows that the following TTS engines are installed on the system: Microsoft Mary Microsoft Mike Microsoft Sam Cepstral Allison-8kHz Sample TTS Voice Read more at: https://www.voiceguide.com/vghelp/source/html/config_tts.htm Share this post Link to post
SupportTeam Report post Posted 10/22/2019 07:53 PM Can you please post the latest ktTts trace file from your system. The file should be in readable text format, like other VoiceGuide traces. Attaching a sample. 1022_ktTts.txt Share this post Link to post
Guest u4910 Report post Posted 10/22/2019 09:05 PM OK, here is one. But the one you posted is not readable either? 1022_ktTts.txt Share this post Link to post

SupportTeam Report post Posted 10/22/2019 09:42 PM Looks like you have configured TTS system to use Cepstral Callie and looks like its working. The text seems to be static, so you could just copy this .WAV file from VoiceGuide's \temp\ subdirectory: C:\Program Files (x86)\VoiceGuide\temp\tts_2_1.wav copy above to a new place and the set the module to just play that .WAV directly. Looks like there are other modules playing static TTS as well, so those modules can be converted over to just using .WAV also. Traces show that the TTS generation only introduces a delay of between 0.1 - 0.2 second on average (for the TTS that is done here) but playing .WAV directly will reduce CPU load, especially if many channels are trying to do TTS at same time, so you will get overall lower CPU load if any static sound files are played from a from WAV instead of TTS generated each time.

Guest u4910 Report post Posted 10/23/2019 01:46 AM OK thanks. That seemed to work. I always use VIM to edit text files and didn't realize that it wasn't reading the encoding properly. Notepad and Wordpad work fine. I also changed the encoding in the vg.ini and see if that makes it even easier. Share this post Link to post
