Siri

The computer that always listens for voice commands used to be the stuff of science fiction. Google has already initiated Ok Google as a code word to listen for further commands on Android devices, and now iPhone users have the jailbreak tweak OkSiri. Normally, Siri requires a long press of the home button to start listening. With OkSiri installed, an Activator gesture tells Siri to be ready for a custom code word.

Once installed, the first step is to define the code word that will invoke the main Siri screen. By default, this word is set to Ok Siri under Settings -> OkSiri. To change the work or phrase, enter the text and then activate and deactivate Siri the traditional way. With the code word configured, the next procedure requires assigning an Activator gesture to OkSiri. This makes it possible to switch the listening mode on or off.

Siri may have improved a lot since its launch in 2011, but the lack of a "back" button on some of its results can be infuriating. This especially true when you're searching for places such as local restaurants. There is a back button on the "Details" page for each individual restaurant that takes you back to your original query, but there is no way to go back once you have accessed the Maps app for directions.

It seems like a no brainer that you should be able to return to the original Siri results without having to ask the same question over and over. However, this does not work anytime you leave Siri to open a separate app. You can however get back to your original search results by following these instructions:

Apple's overhauled Photos application that debuted with iOS 7 earlier this year introduced automatic photo sorting by date and location. A new patent application that surfaced at the U.S. Patent and Trademark Office on Thursday suggests that Apple wants to improve upon this idea by allowing users to tag photos and search for them using Siri.

The patent, entitled "Voice-Based Image Tagging and Searching," describes how the idea works in its abstract: "The electronic device provides a natural language text string corresponding to a speech input associated with the digital photograph. The electronic device performs natural language processing on the text string to identify one or more terms associated with an entity, an activity, or a location. The electronic device tags the digital photograph with the one or more terms and their associated entity, activity, or location." That is basically a long-winded way of saying that you

iOS users with Siri-enabled devices can now access LyricFind's database of over 2,000 music publishers. Siri learned its new trick after Wolfram|Alpha teamed up LyricFind to add a new lyric query option to its search engine. The new service also allows Wolfram|Alpha users to create word clouds of popular terms used in a certain song. However, this feature does not seem to work on Siri at the moment.

iOS users can get the lyrics to almost any popular song by opening Siri and asking “What are the lyrics to (song title)". For some reason completing this task seems to take Siri longer than usual, and it will also refer you back to the web if it can't locate a title in LyricFind's library.
