RIM rolled out an update to developers working with the prototype version of the handset, allowing them to carry out vocal commands to access a range of functions.
Users will be able to use the personal assistant to call up web pages, find directions, check the weather, schedule meetings, make calls, set reminders and play music, CrackBerry reports.
The BlackBerry 10 operating system, considered the company's last chance to remain competitive in the consumer market, was recently delayed until 2013.
RIM has endured a torrid 12 months due to competition from Apple's iPhone and Google Android devices, but also sluggish sales of its BlackBerry PlayBook tablet and a reputation-damaging service outage last October.
It is yet to be confirmed whether the first BlackBerry 10 devices will feature the new voice technology at launch.
