Umm, no. I know of the game but never played or even seen it. I guess the Lex name is kinda obvious choice though cause in both cases it is a play on lexicon. This style of noises on "speech" is kinda my goto nowadays. I think the inspiration mainly comes from Animal Crossing even though their system is way more in depth than my "just record a bunch of syllables and play them randomly on start of a word". And as a funny trivia, these syllables are what from Finnish words for few cat and dog family species. The sound quality is quite horrible too. They were recorded with a laptop mic and the room is way too echoey too since I moved quite recently and don't have curtains etc on my office.
