The increasing adoption of artificial intelligence is anticipated to drive growth in the voice user interface (VUI) market in the coming years. Artificial intelligence refers to the ability of machines to simulate human intelligence. VUI leverages AI technology to facilitate user interaction with various devices. The popularity of voice AI is on the rise, largely due to various third-party platforms that enhance customer experience. Consequently, more companies are integrating AI technology into their growth strategies, which, in turn, is propelling the voice user interface market forward. For example, according to the Global AI Adoption Index 2022 survey conducted by IBM, a US-based technology firm, 13% of organizations were more likely to have adopted AI globally in 2022, with 35% of companies reporting AI usage in their operations, marking a four-point increase from 2021. Thus, the rise in artificial intelligence utilization is a significant driver of growth in the voice user interface (VUI) market.

The increasing popularity of smart homes is expected to drive growth in the voice user interface market in the coming years. Smart homes are residences equipped with connected devices and systems that can be controlled remotely and automated to improve comfort, security, energy efficiency, and overall home management. Voice user interfaces enable residents to interact with and manage various connected devices and systems through voice commands and integration with virtual assistants, thereby enhancing safety and security. For example, in 2023, reports from Smarthomlady.com, a US-based provider of smart home technology information, estimated that 68.6% of active smart home device users in the US would be reported, reflecting a 56.6% increase from 2022. Additionally, it is projected that 53.9% of US households will be automated by the smart home sector by 2023. Therefore, the rising popularity of smart homes is a significant factor driving the growth of the voice user interface market.
