I was driving from southbound on the Dan Ryan (90, 94) and exited onto the Stevenson (55) and noticed that the voice over said “Street Louis” instead of “Saint Louis”. Also, Cermak road was pronounced “CHER-mak” instead of “SIR-mak” as I’m used to.
TTS errors aren’t exactly new though, and ‘street vs saint’ came up on the UK board:

They didn’t really have a solution, so I guess this is just an FYI.
