Siri iPhone 4S

Apple’s A5 processor includes noise-reduction circuitry licensed from a start-up called Audience, and a chip analyst believes that fact resolves an iPhone 4S mystery and explains why the iPhone 4 lacks the Siri voice-control system.

Stephen Shankland of CNET reports:

“Apple’s A5 processor includes noise-reduction circuitry licensed from a start-up called Audience, and a chip analyst believes that fact resolves an iPhone 4S mystery and explains why the iPhone 4 lacks the Siri voice-control system

Audience revealed details of its Apple partnership in January, when it filed paperwork for an initial public offering (IPO) of stock. Teardown work from iFixit and Chipworks revealed a dedicated Audience chip in the iPhone 4, but the iPhone 4S integrates Audience’s “EarSmart” technology directly into the A5 processor, the company’s S-1 filling said.”

Audience when put on paperwork for its initial public offering (IPO) of stock, work of iFixit and Chipworks shows compatible Audience chip in the iPhone 4, as we know iPhone 4S integrates Audience’s EarSmart technology direct to the A5 processor. The Audience’s noise reduction technology for iPhone 4S works only with handset held up near the speaker’s mouth. The iPhone 4S  “EarSmart” tech is built into the A5 processor which is responsible to tackle ‘fair-field speech, it shows that it will catch sound from few feet. It does’nt mean that iPhone 4 isn’t eligible of running Siri well it seems second element leading to Apple’s decision to continue assistant 4S feature only. One more thing can be added to the reason probably won’t see Siri opened up to older devices in the near future.
