Siri leads the virtual assistant world with a 35% market share

Market research from Futuresource consulting claims that Siri is the world's leading virtual assistant with a 35% share of the global market.

Given that Apple's Siri ships by default in basically every Apple device sold these days, the proliferation of Siri doesn't really come as a surprise. What is perhaps more surprising is that in second place was Microsoft's Cortana, which came in with a 22% share. This is, of course, thanks to Windows 10, Cortana having been retired from Xbox.

Google Assistant and Amazon's Alexa hold 9% and 4% market shares respectively. The report states:

Across the leading assistant platforms, Apple's Siri presently holds 35% share globally, reflecting the continued success of the iPhone and the newly released AirPods Pro. Google Assistant and Amazon Alexa hold 9% and 4% market share respectively, due in part to shipments across their 1st party products. Microsoft retired Cortana from Xbox, however, its domination in Windows 10 PCs ensures that Cortana holds 22% market share worldwide. Microsoft is switching strategy to make Cortana more enterprise targeted, with tighter integration into Office 365 and its suite of productivity tools. In China, Baidu's DuerOS posted strongest growth, rising 6% year-on-year to command 15% market share in 2019.

The report notes that whilst some products now include support for multiple assistants, many vendors have been unsurprisingly reluctant to cooperate. Looking forward, it believes that the Voice Interoperability Initiative, a program created to give customers choice through multiple, interoperable voice services, will change this.

The research also commended the advance in speech synthesis, in particular, the move towards neutral Text-To-Speech, and even Amazon's dabbling with emotions in Alexa. Interestingly enough, it believes that beyond the superficial, more natural-sounding virtual assistants actually increase consumers' expectations of their capability, leading to increased engagement.

Overall, shipments of virtual assistants (which for the most part will simply track device shipments for companies like Apple) was up 25% YoY to 1.1 billion in 2019. It is expected that the market could exceed 2.5 billion by 2023.
