Hot on the heels of Amazon's Alexa coming to iOS, Siri has more competition in the voice assistant department. The Google Assistant can now be installed as a stand alone app on the iPhone, iPad or iPod touch. While the Google Search app for iOS includes voice capabilities, the full-blown Google Assistant is more sophisticated and powerful.
Apple is poised to launch its own Siri-based personal assistant accessory, which would compete with the Amazon Echo and Google Home. In fact, according to Ming-Chi Kuo at KGI Securities the chances of Apple revealing the new device at WWDC are over 50 percent. This year's developer conference is scheduled for June 5-9 in San Jose.
