Siri owns 46% of the mobile voice assistant market - one and half times Google Assistant's share of the market
Apple's Siri is apparently the market leader for mobile voice assistants, beating out popular players like Google's Assistant.
This may come as a surprise to some, since Android has a much larger share of the market and Siri is often considered inferior in terms of user experience and capabilities. But Google has been struggling to build awareness about its smart assistant (Google Assistant is on 400 million Android devices as of 2017, according to Voicebot.ai) and as this chart from Statista shows, Siri's first-to-market strategy has made it tough for others to catch up.
Also interesting here is Amazon Alexa and Microsoft Cortana's high rankings, considering neither one is automatically integrated into a smartphone. Alexa's particularly impressive 10% share accounts for the people who use the voice assistant through the Alexa app in order to access their Echo smart speakers - a capability that wasn't even possible until 2017. Cortana, meanwhile, can now only be bought in the Google Play Store.
