Voice search is a smartphone function that allows you to use Google Search by speaking into your mobile device. When using the Google app, this function is known as “OK Google”. Although, recently Google updated its search functionality, revamping the software with a new name: “Google Assistant”. Google Assistant understands language better than voice search alone, using previous queries to derive and predict the context of the next query. However, as most of us already know, you can do more than just search by using voice actions. You can also get directions, set reminders and calendar dates, call friends, access other apps, and change your device’s settings. Google recently spoke out regarding search usage, claiming that approximately 20% of queries through its mobile app and on Android devices are now voice search. As this search method grows in popularity, it’s becoming a far more critical piece of the mobile optimization puzzle.
