Apple has been training Siri voice recognition on the Apple TV to recognize movie and TV show titles in country-specific pronunciations, according to a new report from MacPrime (translated link). While Siri is available in more than 30 countries on the iPhone, on the Apple TV it remains limited to eight — Australia, Canada, Great Britain, United States, Germany, France, Spain, and Japan — and is notably not available even in other countries where the same languages are used, such as Switzerland.
Asked why Siri support on the Apple TV was not available in Switzerland, where residents speak German and/or French, Apple responded by explaining that Siri on the Apple TV was designed to “put a special focus on television and film content,” specifically ensuring that it could quickly and accurately recognize film titles and names of actors, directors, producers, and so forth. To achieve this goal, Apple undertook efforts to teach Siri to recognize specific dialect and phonetic pronunciations for each country.
This likely also explains why it has taken longer for Siri support for other features such as Apple Music to arrive on the Apple TV. The report notes that Apple is working on expanding Siri support to other countries, although the company has not given a firm date as to when this will happen.
