Apple has been known to use cryptic invitations to events relating to product launches; the recently issued official invitation to members of the press, reads "Let's talk iPhone!" and is already stirring up rumours.
According to investment firm Piper Jaffray, Apple's invitation to next week's event may be a hint to a fifth generation iPhone with improved voice recognition technology.
Analyst Gene Munster, in a note to investors, also supports the belief that iOS 5 will have much improved voice control functions, a feature that has been long rumoured for the new iPhone generation.
The first reports that Apple was going to incorporate powerful software features related to voice recognition started as early as April 2010, after the company acquired Siri. The yet to be confirmed partnership with Nuance Communication also leads to the same conclusion. Apple is most likely to shake the market with unprecedented voice recognition integration.
Recent hearsay also suggests carriers will collaborate with Apple at the release of the iPhone 5. For customers, this will translate into a subsidised price of between $200 and $300 with a contract.
Particular strong demand comes from Verizon, one of the top US carriers. Verizon's customers first gained access to the iPhone in February 2011, six months after the company's main rival AT&T. Reports show that about 74 per cent of Verizon iPhone buyers would rather wait for the new model than buy the currently available one.
