A new report is citing the A4 processor that is found in every iPhone 4 as the reason why Apple will never bring Siri to the iPhone 4 or the first generation iPad (via CNET). The report suggests that Apple’s system-on-a-chip A5 processor, as found in the iPhone 4S, contains some highly complex noise reduction hardware which is apparently essential for the optimal performance of Siri in noisy environments. The noise-reduction abilities, apparently based on technology called ‘EarSmart’ developed by a small company called Audience
As such, the A4 processor found in the iPhone 4 and iPad 1 does not contain the same noise reduction circuitry and is the reason why owners of these devices hoping for a Siri-upgrade in future versions of iOS will be disappointed. But, there is one more Apple device other than the iPhone 4S that is powered by an A5 processor; the iPad 2. So how is Siri looking for iPad 2 users?
The key question is therefore, will Siri be coming to the iPad 2 in the future, especially given the fact that the device has the chip that is requried to power it? However, even if the iPad 2 is evidenced to be capable of running Siri, there is perhaps no reason for Apple to bring it to the iPad 2, particularly if looking to the future.
If the rumors are to be believed, then the iPad 3 is peeking around the corner and, as with the iPhone 4S, Siri on the iPad 3 would prove to be an excellent selling point in addition to the high resolution display and upgraded cameras.
While Siri on the iPhone 4 was perhaps a question of ability, perhaps Siri on the iPad is simply a question of economics.
