Workers set up a flat screen display at the Samsung exhibit for the Consumer Electronics Show, Monday, Jan. 9, 2012, in Las Vegas. The 2012 International CES trade show, the world's largest consumer electronics exhibition starts Tuesday.

LAS VEGAS — Talking to the TV is usually sign of extreme agitation, mental instability or loneliness. LG Electronics is set to make it a more rational behavior this year, with a range of TVs that respond to speech.

LG will sell a remote with its high-end flat-panel TVs that contains a microphone. You'll be able to speak into the microphone to enter text on the TV for Twitter updates and Web searches. You won't be able to change the channel or control the volume by yelling at the TV.

LG Electronics USA showed the new TVs Monday, a day ahead of the opening of the International Consumer Electronics Show in Las Vegas. Other companies are expected to show off ways to make it easier to tap into the "smarts" of today's TVs.
