PanARMENIAN.Net - Google has rolled out a new version of its Google Search app for Android devices, expanding voice control functionality across the platform, Digital Spy said.
The 'OK Google' vocal command can now be used on any tablet or smartphone running the operating system, even when the device is locked.
Once the update has been installed, users can turn on enhanced hotword detection via the Voice subsection of the Settings menu.
The Google Search app has also added an Audio History tool for improved vocal searches. This system learns the user's accent and pronunciation habits to provide more accurate results.
The 'OK Google' hotword, which will play an integral role on smartwatches running the Android Wear OS, first appeared on the Moto X smartphone last year.
Google Search's latest app is available as a free download from Google Play.
