No matter where you are, the last thing you want to hear when you call a 911emergency center is, "I can't understand you." But that can happen when call center dispatchers only speak English, and in the increasingly polyglot American society, some people in distress inevitably can't communicate. Calls in a foreign language are an almost daily occurrence in urban counties across the U.S. So, many 911 centers contract with an emergency translation service. Tom Banse reports from Salem, Oregon.
