The 8 Key Elements of Highly Effective Speech

I’d like you to take a moment to experience the following sentence, taken from a recent article exploring the nature of human consciousness: “Neuroplastic mechanisms relevant to the growing number of empirical studies of the capacity of directed attention and mental effort systematically alter brain function.”

Exciting? Hardly! In fact, most of the words you read barely register in your brain, and most of the words you speak barely register in the listener’s brain. In fact, research shows that words are the least important part of communication when you have face-to-face conversations with others. So before you utter another word to another person, memorize this list of the 8 key elements of highly effective speech:

1. Gentle eye contact
2. Kind facial expression
3. Warm tone of voice
4. Expressive hand and body gestures
5. Relaxed disposition
6. Slow speech rate
7. Brevity
8. The words themselves

Effective communication is based on trust, and if we don’t trust the speaker, we’re not going to listen to their words. Trust begins with eye contact because we need to see the person’s face to evaluate if they are being deceitful or not. In fact, when we are being watched, cooperation increases.[1] When we are not being watched, people tend to act more selfishly, with greater dishonesty.[2]

Gentle eye contact increases trustworthiness and encourages future cooperation,[3] and a happy gaze will increase emotional trust.[4] However, if we see the slightest bit of anger or fear on the speaker’s face, our trust will rapidly decrease.[5] But you can’t fake trustworthiness because the muscles around your mouth and eyes that reflect contentment and sincerity are involuntary. Solution: if you think about someone you love, or an event that brought you deep joy and satisfaction, a "Mona Lisa" smile will appear on your face and the muscles around your eyes will soften.

The tone of your voice is equally important when it comes to understanding what a person is really trying to say. If the facial expression expresses one emotion, but if the tone conveys a different one, neural dissonance takes place in the brain, causing the person confusion.[6] The result: trust erodes, suspicion increases, and cooperation decreases.

Researchers at the University of Amsterdam found that expressions of anger, contempt, disgust, fear, sadness, and surprise were better communicated through vocal tone than facial expression, whereas the face was more accurate for communicating expressions of joy, pride, and embarrassment.[7] And in business, a warm supportive voice is the sign of transformational leadership, generating more satisfaction, commitment, and cooperation between other members of the team.[8]

You can easily train your voice to convey more trust to others, and all you have to do is slow down and drop your pitch. This was tested at the University of Houston: when doctors reduced their speaking rate and pitch, especially when delivering bad news, the listener perceived them “as more caring and sympathetic.”[9] Harvard's Ted Kaptchuk also discovered that using a warm voice would double the healing power of a therapeutic treatment.[10]

If you want to express joy, your voice needs to become increasingly melodic, whereas sadness is spoken with a flat and monotonic voice. When we are angry, excited, or frightened, we raise the pitch and intensity of our voice, and there’s a lot of variability in both the speed and the tone. However, if the emotion is incongruent with the words you are using, it will create confusion for the listener.[11]

Gestures, and especially hand movements, are also important because they help orchestrate the language comprehension centers of your brain.[12] In fact, your brain needs to integrate both the sounds and body movements of the person who is speaking in order to accurately perceive what is meant.[13] From an evolutionary perspective, speech emerged from hand gestures and they both originate the same language area of the brain.[14] If our words and gestures are incongruent, it will create confusion in the listener’s brain.[15] Our suggestion: practice speaking in front of a mirror, consciously using your hands to “describe” the words you are speaking.

Before Anyone Else Can Trust You, You Have to Trust Yourself

Is Trust Uniquely Human?

Your degree of relaxation is also reflected in your body language, facial expressions, and tone of voice, and any form of stress will convey a message of distrust. Why? Your stress tells the observer’s brain that there may be something wrong, and that stimulates defensive posturing in the listener. Research shows that even a one-minute relaxation exercise will increase activity in those parts of the brain that control language, communication, social awareness, mood-regulation, and decision-making. [16] Thus, a relaxed conversation allows for increased intimacy and empathy. Stress, however, causes us to talk too much because it hinders our ability to speak with clarity.

When you speak, slow down! Slow speech rates will increase the ability for the listener to comprehend what you are saying, and this is true for both young and older adults.[17] Slower speaking will also deepen that person’s respect for you,[18] Speaking slowly is not as natural as it may seem, and as children we automatically speak fast. But you can teach yourself, and your children to slow down by consciously cutting your speech rate in half. A slow voice has a calming effect on a person who is feeling anxious, whereas a loud fast voice will stimulate excitement, anger, or fear.[19]

Try this experiment: pair up with a partner and speak so slowly that … you … leave … 5 … seconds … of … silence … between … each … word. You’ll become aware of your negative inner speech that tells you that you should babble on endlessly and as fast as possible. It’s a trap, because the listener’s brain can only recall about 10 seconds of content! That’s why, when we train people in Compassionate Communication, we ask participants to speak only one sentence at a time, slowly, and then listen deeply as the other person speaks for ten seconds or less. This exercise will increase your overall consciousness about the importance of the first 7 elements of highly effective communication. Then, and only then, will you truly grasp the deeper meaning that is imparted by each word spoken by others.

But what about written communication, where you only have access to the words? When it comes to mutual comprehension, the written word pales in comparison to speech. To compensate, your brain imposes arbitrary meanings onto the words. You, the reader, give the words emotional impact that often differs from what the writer intended, which is why so many email correspondences get misinterpreted. And unless the writer fills in the blanks with specific emotional words and descriptive speech – storytelling – the reader will experience your writing as being flat, boring, dry, and probably more negative than you intended.

The solution: help the reader “paint a picture” in their mind with your words. Use concrete nouns and action verbs because they are easier for the reader’s brain to visualize. Words like “sunset” or “eat” are easy to see in the mind's eye, but words like “freedom” or “identify” force the brain to sort through too many conceptual frameworks. Instead, our lazy brain will skip over as many words as possible, especially the abstract ones. When this happens the deeper levels of meaning and feeling will be lost.
