Don't know how you feel? Check your voice - call this number (in Korea only)

Not sure if this is something that is going to ring with users but LG Telecom is releasing a service that allows users to analyse the mood of users by assessing their voice tone.

The emotions are classified by different categories such as happy, sad, bored, true or angry. LG Telecom also provides services like 'couple management center,' where users download the 'affection analysis' system.

Hm - how about: I don't know if I feel angry right now, let me just call this number?
