This "revolutionary" speech-to-text VoiceMode capability, available on two new Samsung phones, will allow users to speak into the phone and have the phone convert those words directly into text, it said.

"This new technology will significantly change how people interact with their wireless phones," Peter Skarzynski, senior vice president of Samsung Electronics, said.

"For the first time, consumers can dictate messages directly to their wireless phone, substantially simplifying the messaging process," he said.

Using a related system dubbed QuickPhrase, users will also be able to send pre-programmed short messages such as "Call me" or "Will call you later" by simply speaking those words.

Samsung Electronics has overtaken Motorola to become the world's second largest seller of mobile handsets after Nokia.

Its global market share stood at 13.8 percent, compared with Motorola's 13.4 percent and Nokia's 30.9 percent, in the third quarter to September.
