Text-to-Speech doesn't follow English's grammatical rules... (Instead of saying {Player} says {Text}, it just says {Player} {Text.})

Same in other languages (it's actually weird that the narrator automatically uses the system language instead of the game language or some other setting, maybe I just didn't find it). Not sure if it actually is a bug though.

The narrator simply takes the text output from the chat and reads it using the system text-to-speech software, which is why it reads it as <player> <message> as opposed to <player> says <message>. Remember though that this would have to be localized were it fixed...
