Apple’s Siri seems to be the market leader for mobile voice assistants, beating out popular players like Google’s Assistant.
Siri owns 46% of the mobile voice assistant market — one and half times Google Assistant’s share of the market
Also interesting here is Amazon Alexa and Microsoft Cortana’s rankings are really high, 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, can just only be bought in the Android Play Store.
