Loading dictionary files in SAPI5IBM TTS

[mohammadrezarashad]

Hello. I successfully used your scripts along with IBM TTS files I extracted from an NVDA add-on to use the TTS as SAPI5. The only thing that I couldn't use its dictionary files for my SAPI5 TTS. Would you please help me find out how to load dictionary files for SAPI5 IBM TTS?
I hope my query is understandable.

I don't think this is possible with the SAPI spec. @datajake1999, thoughts?
