Keep your voice down
A low-pitched voice inspires confidence from those around you, according to a study from McMaster University in Canada. You don’t have to fake it—relax before a speech or important telephone call by keeping your lips together and repeating “um hum” a few times, suggests Forbes body language expert Carol Kinsey Goman. Stress can constrict your vocal cords, making your voice come out higher than usual.
Look coworkers in the eye
People often make eye contact only 30 percent of the time, according to an analysis by communications analytics company Quantified Impressions of more than 3,000 people speaking to individuals and groups. To make an emotional connection, you should at least double that, says company president Noah Zandan. Try holding someone’s gaze for ten seconds at a time for one-on-one conversations, and for 3 to 5 seconds in group settings.
