An obvious way to detect lies is to keep asking the details. The liar will probably not be able to keep up with all the lies. He or she will not be consistent with all the lies and can be caught this way. It is likely that the person does not give you specific details while lying such as persons involved in the story or places visited. The voice pitch is also not normal.
Carefully examine how they are speaking. If they try to relax, breathe deeply or pause before saying something, it is likely that the next sentence is going to be a lie.

A liar can be easily detected if he or she suddenly changes the topic of conversation. Or if you change the topic suddenly, the liar will not try to get to the original topic while a truthful person will try to clear up things.
