Earlier quoted context omitted.
a) I went to a Talon Voice cheat sheet and copied them out because I didn’t remember them. Is plex not right? b) Talon Voice is a configurable voice engine, the commands are something you setup and people use common shared starter packs and then edit their own, so there isn’t a formal standard, plex might be different in some setups? c) they just have to be sounds you can vocalise which are distinct from each other,…
But all of the other words begin with the letter they represent. Plex ends with it. It sticks out quite a lot. One could make "Pit" be "t", with that logic.
This property is also not true for "sit" or "crunch".
