According to a recent Apple Insider report, the iPhone's voice quality chip supplier Audience has recently revealed in a note to its investors that the next-generation iPhone - the iPhone 5, as it is widely referred to in reports - was "unlikely" to be equipped with the company's chips.

In its note to the investors, Audience highlighted that its voice quality chip will be left out of the iPhone 5, saying that that the company "now believes that it is unlikely that the OEM will enable Audience's processor IP in its next generation mobile phone."

The company also added alongside that it was "not aware of any intended changes by this OEM to its use of Audience's processors or processor IP in prior generations of the OEM's mobile phones."

The disclosure by Audience comes as a surprise because of the fact that Audience's earSmart voice and audio circuitry was earlier integrated in the A5 chip which powers the iPhone 4S, and the stand-alone Audience chips were used by Apple in all the earlier models of the iPhone, the iPhone 4 included.

With Audience revealing in its note to investors that its noise-suppression tech will be given a miss on iPhone 5 - which will likely be unveiled by Apple at a September 12 press event, and will probably hit the markets by September 21 -, Apple Insider is speculating that the forthcoming iPhone will apparently feature Apple's own in-house voice quality tech
