Google sees voice search as core

Google has said it sees voice search as a major opportunity for the company in building a presence on the mobile web.

The company's vice president of engineering made the comments during a wide-ranging discussion at the Web 2.0 Expo in San Francisco.

"We believe voice search is a new form of search and that it is core to our business," said Vic Gundotra.

SearchEngineLand editor Greg Sterling agreed: "If done right, it could be a valuable strategic feature for Google."

Mr Gundotra acknowledged to the audience that "voice recognition in the early days was a nice trick but not very usable".

There were early complaints that Google's offering could not understand accents other than American and that results were often garbled.

"Look how far we have come. I get the advantage of looking at daily voice queries coming in and it's amazing. It's working. It's reached a tipping point. It's growing and growing very, very fast and we are thrilled about it," said Mr Gundotra.

He declined to share figures about just how many queries the company deals with via voice search.

However, Mr Gundotra did say: "It's one of those technologies we think gets better with usage.

"We launched it on the iPhone and have seen a 15% jump in accuracy because, as more people use it, we collect more data and our accuracy gets better."

'Queen's English'

In 2002, Google Labs introduced a service that allowed users to search with a simple phone call. The company admitted it "wasn't very useful because the results were displayed on your computer and Google discontinued it".

Six years later, the search giant introduced an improved feature under the Google Mobile App for the iPhone.

It is also available on the Android based T-Mobile G1 and last month was introduced on the BlackBerry as a free download. The New York Times's Gadgetwise blog rated the BlackBerry version the "App of the Week" earlier this week.

Early iterations that worked best with North American accents had problems understanding other accents, including British. BBC technology cCorrespondent Rory Cellan-Jones reported in November last year that his attempts to use it were "pure gibberish".

For example, his query about the next train, West Ealing to Paddington "delivered some useful information about 'neck strain' - but no train times".

Those problems have since been largely ironed out and Google said it was continuing to work on improving the accuracy of the service. This, Mr Sterling said, is crucial if the company wants it to give them the edge in the marketplace.

"My view is voice search could be a strategic differentiator if it works well. It depends on how much better Google's system is compared to, say, Yahoo's or Microsoft's.

"If they come up with a really great version that is really accurate, it could retain users and likely increase search usage for Google," said Mr Sterling.

"Stay tuned"

At Web 2.0, Mr Gundotra also talked about a web-based version of Google's e-mail service, Gmail.

He demonstrated a "technical prototype" on the iPhone and the G1 and said "Stay tuned" for a release date.

Mr Gundotra said the prototype used HTML 5, an as-yet incomplete version of mark up language of the world wide web.

He revealed that Google would create a whole suite of offline apps using HTML 5 and that "we are going to be leaders in taking advantage of HTML 5".

Mr Gundotra also said that engineers were working hard to bring the Chrome browser to the Mac and that while there was no date for delivery, "we are making progress to get it out as fast as we can".

Twitter purchase

During a question and answer session, Mr Gundotra was quizzed on rumours circulating in the blogosphere that Google is looking to buy the micro-blogging service Twitter.

"I'm a big fan of Twitter but we don't as a policy comment on rumour or speculation," he said.

Meanwhile, Twitter co-founder Biz Stone has said that he has been "flooded with requests for a response to the latest internet speculation about where Twitter is headed".

In a blog entitled Sometimes We Talk, Mr Stone wrote: "It should come as no surprise that Twitter engages in discussions with other companies regularly and on a variety of subjects.

"Our goal is to build a profitable, independent company and we're just getting started."

Google introduces phone services

Google has strengthened its mobile services with the debut of a service called Voice that could be a challenge to Skype and other phone firms.

It lets customers make cheap international calls and gives them a speech-to-text feature for voicemail.

The services are available thanks to Google's acquisition of phone firm GrandCentral which gives users a lifelong universal phone number.

"This could be big. Google is seen as disruptive," said analyst Jon Arnold.

"They are a wild card in telecoms and wireless but this is Google and they are very smart at what they do.

"The core of Google's business is search and for a long time the industry was concerned about the GrandCentral acquisition. What was the fit? What was the motivation? It will be interesting to see where they ultimately go with this," said Mr Arnold, principal of analyst firm J Arnold & Associates.


Table stakes

Google Voice is the first major update to GrandCentral, which Google bought for an undisclosed sum, thought to be $50m (£36m) in 2007.

The service gives subscribers one number that lets them route all their phones through - home, office and mobile.

Users also get a single voicemail account regardless of which phone messages are left on.

Google Voice is the latest attempt by the company to reach out beyond online search and advertising.

Domestic calls will be free but international calls will require users to set up a Google Checkout account. Calls to landlines in the UK will cost 2 cents per minute.

EBay's Skype offers free domestic and international calls made over the internet from one computer to another, but there is a charge to landlines and mobile phones.

Skype president Josh Silverman told analysts and investors that "chat and voice will become table stakes". He also revealed that the company is adding 350,000 new users a day and is on track to do more than 100 billion calling minutes in 2009 alone.

Google does not view the service as a threat to Skype or other telecom companies any more than its Google Talk offering, which lets users chat over the internet for free.

"This is about allowing your existing phone to work better," said Craig Walker, now group product manager for real time communications at Google and co-founder of GrandCentral.

"It's not that we are replacing your phone, we are giving [it] the ability to work better," he said.

He declined to say how many users had signed up. Google Voice is currently only available to former GrandCentral users.

"Chore"

Google Voice also allows all voice messages to be turned into text which will then be sent either through an e-mail or an sms.

"Voicemail can be a pretty negative experience for a lot of people," said Mr Walker.

"Now it's about putting the user in control. We will transcribe voicemails and convert it into text and put it in your inbox so that it's searchable and you will always have a record of that voicemail.

"Voicemail need no longer be the chore it has been in the past," he declared.

Mr Walker demonstrated its search capabilities by displaying the 1,000 or so voicemails he had accumulated while testing the system over the past few months.

By typing "pool man" in a search box, he located an old voicemail from December 2008. Returned results were in both text and audio form.

"I would never have been able to find that number. The phone company deletes everything for you after a couple of weeks and the scrap of paper I wrote the number on is long gone. This feature makes your voicemail a pretty powerful tool," said Mr Walker.

Opportunity

Google boss Eric Schmidt said he viewed mobile as the next big opportunity.

At the recent Morgan Stanley Technology Conference in San Francisco, Mr Schmidt said he believed mobile search revenues would over take those on a PC within a few years

"The fact of the matter is that mobile devices are going to be the majority of the way that people get information," he said.

A report in February by the Kelsey Group suggested that "about 20% of U.S. cell phone subscribers are on the mobile web right now and only about 5.2 million are doing searches".

Mr Arnold said that if Google perfected its speech-to-text feature to other languages, all bets were off.

"This could be very powerful given the globalisation of markets. Language is another barrier and when you break that down, the world of communications opens up and globally this has exciting opportunities," he said.
