We watch more than we listen, particularly when we are with people unlike ourselves. We tend to let instinct drive us and base our judgement on non-verbal attributes. More often than not, an unfortunate turn of phrase, raised voices, or a 'hmmm' in the wrong place will mean something completely unintended, especially in multi-lingual scenarios. Good speakers are practiced at aligning their verbal and nonverbal skills for maximum impact. The key to effective communication is to emphasize spoken words with body language so that what the listener sees and what he hears are the same thing.
Information needs to be listened to, understood, remembered and believed.
Here are some body language strategies you can use to improve your communication techniques. Observe yourself in action. You may sound normal to yourself but to others your voice may be too high-pitched, your eyebrows furrowed or your face set unintentionally in a grimace. Be aware of behavior that may distract your audience. Practise in front of a mirror to get your presentation spot on.
