Not sounding "stupid" at all- yeah I live in the Sunset District in western San Francisco, which has a huge chinese population-most of them do not speak English.
So what happens is a siren first, a message in English next, then a message in chinese last. The thing is-that PA system is not powerful enough to really get out a clear voice message to everyone. I listen now and then to the ham net that checks in at noon to report on what they heard-and most of them report hearing voice, but not understanding the actual message.
