Why is Siri limited to 8 countries on Apple TV? Apple teaches movie & TV show pronunciations for each country
While Siri voice search is a core feature of the new Apple TV, right now it’s limited to only eight countries: UK, US, Australia, Canada, Germany, France, Spain and Japan. In other regions, the Siri Remote is simply called the Apple TV Remote (not to be confused with the old Apple TV Remote) and pressing the mic button just opens the Search app.
This is despite the fact Siri on iPhone is actually available in 30 countries, so it wasn’t clear why Apple had pinpointed only a subset of those. It turns out, according to a chat with Apple by MacPrime, that there are some clever optimizations Apple makes with Apple TV Siri to improve speech recognition.
