I really wish all the voice dictation/transcription had better language support. I'd really like to be able to say "Send a message to <my wife> in Spanish" and have it use Spanish dictation, and similarly to say "Read the last message in Spanish" when I'm using CarPlay. Perhaps at some point soon it will just get good enough that it'll detect which language is being used automatically, but right now it's pretty annoying for dual-language households.
