Listen to Siri's More Natural Voice in iOS 11
As you'll hear in the video, Siri sounds more human, adopting better pronunciation and different inflection depending on what's being said. There are also a lot of other improvements, which are covered in our Siri video and in the post below.
In iOS 11, Siri uses on-device learning across all of your devices to get a more complete picture of your interests, preferences, and routines. Because Siri now syncs across multiple devices, Siri learns more about you and your interactions with Siri are always the same regardless of whether you're using an iPhone, iPad, or Mac.
Siri can now do things like suggest a topic you might like in Apple News based on Safari browsing habits, or suggest a Calendar reminder for an appointment you've booked in Safari. Siri might also make QuickType word suggestions based on things you've recently viewed -- names of movies or places, for example.
Siri has built in translation capabilities in iOS 11 and can translate English to Chinese, French, German, Italian, and Spanish, plus with music enhancements implemented for HomePod, Siri can play music you like and offer up answers to music-related queries like "What song is this?" or "Who's the drummer in this band?" when you're listening to music.
You can even type to Siri using a new "Type to Siri" Accessibility option. This makes it easier to communicate with Siri when speaking isn't an option.
