Maciej Zasadzki ADVICOS Report post Posted 11/10/2025 09:34 AM I have two questions: I have a question regarding the parameter SAPI_TTS_Speed. Specifically: Does this parameter work when using the Google Cloud TTS engine (EngineType=Google) within VoiceGuide, or is it only applicable when using a SAPI-compatible TTS engine? Can the SAPI_TTS_Speed parameter be modified dynamically (for example, as a variable in Evaluate Expression), or can it only be changed statically in the VG.ini file? Would it be possible, for simplifying the call flow, to enable the ASR_NLP parameters directly in the Play module — instead of having to add in a separate Evaluate Expression module variable ASR_NLP_PlayModuleName? Thank you in advance for your help. Share this post Link to post
SupportTeam Report post Posted 11/10/2025 10:09 PM SAPI_TTS_Speed is a setting that can be used on some SAPI engines. it does not affect Google Cloud TTS generation. There is no option to modify it midway through callflow. A Play module in VoiceGuide v7 and prior does have functionality to set parameters. A Run Script module can be used to set multiple parameters in VoiceGuide v7 and prior - using the RvSet and RvSet_RvList API calls. https://www.voiceguide.com/vghelp/source/html/com_rvset.htm https://www.voiceguide.com/vghelp/source/html/com_rvset_rvlist.htm Share this post Link to post
