Speech technology company Nuance, which has been suing Vlingo, said on Tuesday that it is buying the mobile voice-software firm for an undisclosed price.

Of course, now the two firms have nothing but nice things to say about each other.

“Vlingo and Nuance have long shared a similar vision for the power and global proliferation of mobile voice and language understanding,” Vlingo CEO Dave Grannan said in a statement. “As a result of our complementary research and development efforts, our companies are stronger together than alone. Our combined resources afford us the opportunity to better compete, and offer a powerful proposition to customers, partners and developers.”

It wasn’t that long ago that Nuance was asserting that Vlingo’s vision was a little too similar. In August, a jury in one case found that Vlingo did not infringe on Nuance patents. However, Nuance noted at the time that it had other pending actions against Vlingo that it planned to continue pursuing.

Apparently, Apple’s introduction of Siri has convinced the two firms there are bigger fish to fry.

“Inspired by the introduction of services such as Apple’s Siri and our own Dragon Go!, virtually every mobile and consumer electronics company on the planet is looking for ways to integrate natural, conversational voice interactions into their mobile products, applications, and services,” Nuance mobile unit head Mike Thompson said in a statement.

Bygones.

According to a new survey from Vlingo, a company that develops speech-recognition technology for mobile phones, 26 percent of its nationwide sample of 4,816 mobile phone users said they sent texts while driving. This despite laws against Driving While Texting in some seven states and some nasty DWT-related accidents. The states with the highest percentage of DWT drivers: Tennessee (42 percent), New Jersey (35 percent), Alabama (34), Idaho (33) and Oklahoma (31.7).

Ironically, 83 percent of the people surveyed said they feel texting while driving should be illegal.

“In just one year, the public conversation about the issue of DWT has escalated, particularly in the wake of some high-profile accidents,” Dave Grannan, chief executive of Vlingo, said in a statement. “Texting is such an integral component of our daily lives, and the cautionary tales about DWT danger have not stemmed the tide. We predicted last year that this problem would get worse, and it has since more people are texting. The good news is that many state legislatures are starting to take up this issue, and today more advanced technologies exist that can increase safety on the roads.”

My God, if one in four drivers admit to driving while texting, how many more were too ashamed to?
