As of now, it is expected that Apple Inc. will announce iOS 9, its upcoming operating system, at the company's Worldwide Developers Conference (WWDC) on June 8. According to latest rumors, it is likely that Siri will be more colorful and possibly be smarter.

According to Latin Post, usually the Siri personal assistant available on iOS devices appears black and white while users are interacting with it. However, Siri is colorful on the new Apple Watch. According to 9to5Mac, it is expected that with the launch of iOS 9 update, the Cupertino-based tech titan will make all versions of Siri even more colorful.

A report in CNet says that making Siri more colorful would make it more inviting.

Although no information is available regarding the other tweaks or improvements for Siri, it is expected that the personal assistant may perhaps use some work. Since Siri has been in 2011, it has been undergone several improvement. Nevertheless, both Google as well as Windows Phone have their individual personal assistants, for instance Google Now and Cortana, respectively. According to a test by Gene Munster, an analyst with Piper Jaffray, Apple now wants to concentrate on making Siri smarter because Google Now is more precise compared to Siri.

When Apple introduces Windows 10 later in 2015, it will utilize Cortana on all its devices, counting tablets and PCs. In fact, people who enjoy their Cortana experience on laptop or desktop may possibly also buy a Windows Phone.

An earlier Reuters report stated that Cortana may even appear within iOS devices, forcing Siri to prove she is worth using.

However, Siri is not as advanced as Cortana, which answers questions and even sets up tasks just like Siri. In addition, Cortana also delivers reminders and alerts. In fact, Siri can easily incorporate that feature with a view to match its capabilities with Cortana. In addition, iOS 9 will come with several bug fixes as well as improvements. However, iOS 9 is likely to have fewer new features as Apple is expected to focus on making the OS more stable and reliable.

Apple has already released several iOS 8 updates. While iOS 8.3 is the latest OS available to the public, but Apple is already in the beta phase for iOS 8.4.
