Google has acquired California-based voice messaging start-up SayNow for an undisclosed sum.
The SayNow service enables voice messaging between individuals or groups. SayNow is accessible through Facebook, Twitter, MySpace, Android and iPhone applications.
According to SayNow founders Ujjwal Singh and Nikhyl Singhal, the company's services will be combined with Google Voice.
"We believe combining forces with the Google Voice team will let us innovate in new and unexplored areas," Ujjwal Singh and Nikhyl Singhal said.
The planned acquisition of SayNow is the latest in a string of strategic acquisitions for Google aimed at boosting its competitiveness, particularly with traditional telecoms companies and IP telephony providers like Skype.
In May 2010, Google announced plans to acquire Norwegian internet telephony company Global IP Solutions for $68.2m. In November 2009, Google said it was to acquire internet-based calling software firm Gizmo5 to boost Google Voice.
