Google is said to be working on artificial intelligence technology that could surpass the capabilities of Apple's Siri voice assistant, a development that comes as Apple prepares to launch the next iteration of its iPad tablet.

Google, the Internet search leader, plans to reveal a new ‘Assistant’ product by the fourth quarter of this year, according to a report by TechCrunch's Alexia Tsotsis, who cited an unnamed source at the company.

The feature will be personalised and make use of Google's data collection regarding how people behave online and will be "less about returning search results and more about accomplishing real-life goals," the report says.

The Android operating system has had voice commands for soem tiem but Google hasn't promoted Voice Commands so many people using the mobile OS haven't played around with it.

Even so, Android Voice Commands, at least in their current state, lack the panache of Apple's Siri. In fact, Apple boasts that you can ask Siri to do things without using choppy or difficult-to-remember commands. So instead of saying something like "Record note, pick up shirt from dry cleaner," you could say, "Remind me to pick up my shirt from the dry cleaner."

However, as Google consolidates individual user data from across its products it have powerful tools to enhance its products, privacy concerns notwithstanding.
