9to5Mac are reporting that Apple may be bringing Siri to the Mac desktop this Fall as part of OS X 10.12.
On a report on their website they say;
When a user clicks the Siri button, a dark, transparent Siri interface will appear in the top right corner of the screen, as shown in our mockup by Michael Steeber. This interface will feature colorful sound waves to indicate speech input. The interface design in testing is not finalized and may still change before the summer introduction, according to sources.
Siri on the Mac will have its own pane in System Preferences and users are said to also have the option to choose a keyboard shortcut for activating the service. Like with recent versions of iOS, users will be able to enable Siri at the first startup of OS X 10.12, according to sources. If the Mac running the new OS X version is plugged into power, a “Hey Siri” command will work much like with recent iPhone and iPad models.
It's not clear how this could be integrated into third party apps such as Pro Tools, but it's likely to include basic functionality such as file and other OS based commands across the entire operating system.
If you are an iOS user then you may have had mixed results when using Siri, asking it to call your Mum and finding it playing a track by Moby instead.. or even worse! If it did work on Pro Tools then who knows what could happen unintentionally - imagine sitting in the control room tracking a vocal and saying 'that's not very good' and finding the track deleted! It's enough to send one into a cold sweat.
