Effective communicators use the full range of the voice (tone, quality, musicality of the sound, pitch and volume, pause and emphasis and resonance of the vocal presentation) to enhance whether others will be willing to listen and the way the message is cognitively and emotionally perceived.
The ability to produce sound and create speech emerges from a complex process of the use of breath, the vocal folds inside the larynx and the oral cavity which acts as an air resonator. The oral cavity does much to shape and to enhance quality of sound and tone in voice. Tension in modern day life often creates obstacles for the optimal use of the voice. Negative emotion and stress impedes breathing and constricts the muscles around the larynx impacting vocal quality. The shaping of the pharynx and oral cavity may also be jeopardised by habitual holding patterns created by underlying emotions such as anger or fear, i.e a clenched jaw or a stiff tongue. When the shaping of this air resonator is limited by such emotional patterns, tone will be negatively influenced. This could mean that while you have a perfectly rational and sound message to deliver, interference in these aspects could undermine the message, rendering it dull, lacking conviction or worse, communicating the underling feelings of aggression.
While there are no specific standards and each case is different, shaped by a multitude of factors including culture, common mistakes are speech rate that is too fast, a lack of resonance and lack of use of modulation making messages monotonous and dull. Typically, leaders who are able to manage their stress both mentally and physically are best at enhancing their vocal quality and clarity. Tiredness, resentment or stress in the vocal tone can also be quickly spread through a team with viral speed.
Language is obviously what gives the sound meaning. Choice of words, use of emphasis, structure of messages all have vital importance to how a message is perceived. We know for instance that use of strong and direct emotive words, reflects emotion of the individual but also illicits that emotional response in others. This can be used both positively and negatively. While this can be inspirational in a speech, it can also be detrimental in casual discussions. Strong statements like “she is never on time”, leaves people hopeless with no room for improvement. Small adjustments to word choice can create a more Resonant communication message. For example “ She tends to be late. Would you mind finding out what is causing this?” The intention of the message is similar but the expression and delivery is more positive and effective.
Voice and linguistic choices are of direct importance in good leadership. Leaders are often not aware of the impact of these two hidden tools and yet, all humans respond to the presence or absence of these elements. Monica Singer , head of of Strate said in Leadership Fables: “Communicate who you are and be aware that the words you use become and you become the words you use.”
