Several years ago I spent over two months working out how to integrate Text To Speech and Speech To Text (TTS/STT) into any windows program I wrote in Delphi, originally for a powerful flat-file search engine. Does anyone know if TTS/STT is useful on windows 10+ or have any use?

I was thinking about redeveloping the search engine into a stand alone program which can be used as a fast and light query tool with trigger functions, it can be made into a "reply bot" or used with a server like Apache, but without the old IBM mainframe mentality being readopted as "AI" and "social media" everywhere today. low-level Independent and secure droid like systems sound more fun to develop.
