End-user spending for the worldwide virtual personal assistant (VPA)-enabled wireless speaker market will reach $2.1 billion by 2020, up from $360 million in 2015, according to Gartner, Inc. (www.gartner.com). By 2020, 3.3% of global households are forecast to have adopted a VPA-enabled wireless speaker.
"Last year, the VPA speaker market essentially consisted of end-user spending focused entirely on Amazon Echo, a wireless speaker with an array of embedded microphones to capture and respond to users' far-field voice commands for Amazon's VPA — Alexa. Later, Amazon introduced the Tap and Echo Dot," said Werner Goertz, research director at Gartner. "By 2020, competitors' products and third-party implementations of leading VPAs (Google Assistant, Apple's Siri and Microsoft's Cortana) will likely have ramped up.”
VPA speakers, especially those that are wall-powered, allow for multiple devices to be owned by a household and installed in a home. The value of the device is derived from the ease of use and the natural, intuitive interaction model. If this value is recognized by all household members, it will drive the desire to have terminal access throughout the entire house, not just in one room.
"A significant number of households could therefore have more than one unit, or even one per room," said Goertz. "With smaller form factors, price erosion over the years and potential subsidization models, we expect that 75 percent of households with VPAs will have one, 20% will have two, and 5% will have three or more devices by 2020.”
Today's VPAs are limited in vocabulary and contextualization, but they will improve in the future. While speech-to-text conversion has matured since the early days of voice recognition, it is the semantic interpretation of the spoken word, the contextualization of the vocal expression and the rendering of a meaningful response that still require optimization.
Gartner expects that by 2020, a natural-language interaction could be delivered that satisfies users and creates scenarios with significantly improved value. Consequently, adoption of VPA interaction, especially in commercial applications, will occur and drive unit sales for VPA speakers.
"The widespread adoption and proliferation of VPA speakers could result in a significant number of online shopping orders in the home being initiated from a VPA speaker, rather than a laptop or mobile device," said Goertz. "Vendors that are able to create an intimate, familiar relationship with the user will be able to contextualize ordering to the extent that preferred products will be proposed, and processing details will already be captured. As a result, the user's propensity to purchase products and services using VPA systems should increase, transactional friction could be reduced and the overall user experience would be improved."
