Use the source and the voice will follow. Google’s voice search for Apple’s iPhone, that is.

Although Google said they were prepared to ring their bells for the new voice search app for the iPhone as early as Friday, Apple’s App Store remained silent to the matter all through the week-end, since the feature was nowhere to be found.

Now sources say that iPhone users should look for the application on Monday, when Apple is expected to render the voice search to go live on their App Store. The reason: some communication issues between the two companies.

The search giant submitted the app for review to Apple Incorporated earlier this week, while on Friday, the latter gave the go-ahead to the voice search tool, leaving everybody to believe that it would hit the App Store that same day.

Nevertheless, the update to the Google Mobile App for the iPhone is conspicuously missing in action, raising questions about Apple’s procedures with regards to third-party developers and their applications for the company’s gadgets.

The voice search software, which will come free of any charge for iPhone users, enables the latter to ask their smartphone any questions, the sound of their voice being afterwards made into a digital file. Then, the file is sent to Google’s servers, which will make out the words before pushing it forward to the company’s search engine.

In a blink of an eye, the iPhone will then display the results for the queries, along with some local information, where possible.
