Hello. i highly appreciate the information you provided, and i have applied the changes recommended by you. The issue of the GrammarPolice turned out to be something completely not GTA V / LSPDFR / GrammarPolice related. If it helps anyone facing similar issues, please very thoroughly inspect your microphone settings, i was pretty sure that my microphone settings were correct. but after checking for third time, I've realized the default microphone was somehow changed to one in my webcam, which caused the poor detection. Switching back to my normal microphone fixed the issue! :p
