A new Web site is promising free calls, provided they can listen in.
Pudding Media’s Web site is a beta version of technology the company hopes to offer up to mobile carriers, VoIP phone companies and Web publishers. Software monitors your conversation, looking for keywords which, when spoken, will trigger relevant advertising to pop up on screen. It also uses certain demographic information you provide — gender, age range, and zip code — to ensure relevancy.
In their FAQ page, the company takes pains to note that it’s not actually spying on you. Calls are not recorded and can’t be reconstructed from keywords, nor are any actual humans listening in on the call. It’s all done by software.
