The first announcement at the Apple October Event was the introduction of the Apple Music voice plan which costs just £4.99 and allows for access to the full Apple Music library with one condition: it must be controlled through Siri. How exactly this will work is unclear: how does the Now Playing UI work, can you control playback through that or do you have to use Siri?

As well as this Apple is adding lots of new playlists with titles which are ‘optimised for voice’. These new playlists are available for all users creating an optimised voice experience for all plans. To help introduce these new voice optimisations there’ll be a new section within the app labeled “Just Ask Siri” featuring tips and playlists designed to aid the user experience.
The new Apple Music Voice Plan will be available in 17 countries on release later this autumn and will feature a free 7-day trial which can be activated within Siri. This trial also has no auto-renewal which for me is a feature I wish was implemented more across trial plans.
