How to fix the problem with text-to-speech recognition?

Question

VBScript

Hello, tell me how to fix this problem, it says: "Class is not registered"
In the script it was written: CreateObject("SPEECH.SpVoice")
I understand that the class is not registered, I went into speech recognition > There was no Russian language for text-to-speech recognition.
I installed TTS from the Internet, the computer accepted it, but even after rebooting it did not display it in speech recognition
