Sex, Bombs and Burgers author Peter Nowak explains how Google Voice in Gmail has nothing to do with giving you free phone calls. It’s actually here to help Google perfect the next generation of search.
Yesterday’s most exciting news was Google’s introduction of free voice calls to Gmail. In a nutshell, if you have a Gmail account, you can now make free calls from your computer to real landlines and mobile phones in North America. You can also call the rest of the world for peanuts, with many countries costing only 2c a minute.
The announcement is significant for a number of reasons. For one, it’s direct competition for Skype, which was already pretty direct competition to landline and mobile phone companies. Skype has made calling virtually free – I currently pay about $US35 a year for unlimited calls within North America through its SkypeOut service, which is obviously a fraction of what phone companies charge.
In the US, the computer-based Gmail service works nicely with Google Voice, which is another free calling service that lets smartphone owners use their data plan rather than their voice plan to make calls. In other words, you don’t actually need a voice plan to make phone calls with Google Voice; just the data connection will do. And while the Gmail service is currently shackled to the computer, there’s no realistic reason why it’ll stay that way.
Here’s why Google will beat Skype and every other phone company: to those other companies, it’s still about phone calls and figuring out how to make money from them. But, because the actual cost of making a call over the internet is almost zero, Google can afford to swallow this rather incidental cost as a future investment toward its real business: search.
In Sex, Bombs and Burgers, I talk to Franz Och, the man behind Google Translate. The company’s award-winning and pretty accurate service uses statistical machine translation, an algorithm that studies patterns in different written languages and then predicts the results in another language. The system’s accuracy is predicated entirely on the number of documents it has to work with; the larger the comparison database, the more accurate the translation.
In 2007, the search company launched Google 411, a service that you could call and ask questions, such as the address of a business. The service would send you the requested information back in a text message. The purpose of 411 wasn’t so much for Google to provide you with a rather convoluted information delivery system, but more for the company to gather voice samples to use in building a better voice search system, in the same way that documents were used to build Translate’s database.
Och, in building his original translation system, used United Nations documents because there were millions of them, and they were all already translated into the UN’s six official languages. It was a treasure trove of information. Google 411 was a similar early attempt at building a database and the effort bore fruit with the launch of voice-activated search on the iPhone in 2008, but it wasn’t exactly the same jackpot as the UN documents largely because it wasn’t that useful to consumers.
Google’s computers process the information in your messages for various purposes, including formatting and displaying the information to you, playing you your messages, backing up your messages, and other purposes relating to offering you Google Voice.
That “various purposes” clause is pretty nebulous and can certainly include research and development of search algorithms.
In other words, free phone calls are the jackpot that Google has been looking for. While Skype and phone companies continue to try and find a way to squeeze pennies out of phone calls, for Google it’s extremely valuable to give them away for nothing because it will help the company develop the next generation of search. After all, typing our searches into a web browser is far from the most efficient way of finding information. Saying what we want is much better, and it’s how we’ll primarily be searching in the not-so-distant future.

Update: Google got back to us and are denying this theory entirely. Here’s their statement:
Actually, it is about free calls. We’re not using call phones in Gmail to improve our voice search features. The revenue from international calling will cover the costs of free calls, and we’d encourage you to give your friends overseas a ring!
