Boost your leadership: the best techniques for speaking out

Successful public speaking is a prerequisite for leadership. The company is a microcosm made up of postures and communication, with demanding interpersonal skills. Managers need to master the art of speaking in order to establish their legitimacy and win the trust and support of their staff. Fortunately, knowing how to speak is not something you're born with, it's something you learn and work on! Between naturalness, strategy and improvisation, it's a question of acquiring know-how as well as interpersonal skills. So what are the best techniques for successful speaking? Nicolas Bret-Morel, actor, director and trainer specialising in public speaking, explains.

Leadership: elements of definition

Everyone has their own idea of leadership! For some, it's the art of motivating. For others, leadership means results. Still others need to feel inspired by a leader. In any case, the notion of leadership is not new. And neither is its link with communication - by extension, speaking out!

What are the qualities of good leadership?

Nicolas Bret-Morel gives instructions to the actors in his theatre company seated on the edge of the stage.

Successful speaking requires leadership and vice versa. It is therefore essential to identify the key elements of leadership if you are to make an impact when you speak.

Key words in leadership

VISIONARYVision and sharingBeing a leader means having vision and some share with others.
MOTIVATEEncourageOne of the main functions of a leader is to motivate.
EMPATHYEmotional intelligenceWe also talk aboutemotional intelligenceThe ability of leaders to put themselves in other people's shoes and understand their concerns.
CREATIVEImaginationLeaders are able to create an environment that encourages all members of their team to develop their skills and potential. imaginationto contribute to the joint project.
REQUIREMENTSetting an exampleA good leader sets the bar high for his people because he wants to achieve his objectives and get the best out of his team. They must also be exemplary and demanding of themselves.
LEADVisitThe leader must be in the lead to lead and guide to his team.
CREATING A TEAMCollaborateThe leader seeks to work as part of a team to achieve a common goal.
IMPROVEQuestioningThe leader seeks continuous improvement at all times.

To sum up, leadership has nothing to do with hierarchy or with imposing. Rather, it is an attitude adopted by people who want to something different. They pass on their convictions to others through optimism to achieve a common goal.

Identifying and overcoming your own fears: a prerequisite for leadership

Imaginary fears represent 92 % while real fears represent only 8 %.

The lack of leadership skills identified by participants in training courses often stems from their own fears. What we also call limiting beliefs.

A limiting belief is a a body of knowledge, thought or way of life inculcated from childhood. In other words, a package passed on to children by parents, teachers... and by everyone around them. Added to this are the beliefs acquired in adulthood, as a result of life experiences.

The result? A belief system that determines the direction and quality of everyone's life. In both the personal and professional spheres.

The remedy? Replace limiting beliefs with energising beliefs.

Example :

One of the prerequisites for improving leadership skills when speaking is to replace limiting beliefs with energising ones.

Example:

Table presenting the exercise on limiting beliefs. Table header: the limiting belief is "My English is not good enough to express myself in a professional context". Column 1, line 1: How has this belief hindered me before? Column 1, line 2: I have avoided taking part in meetings in English and speaking to English-speaking colleagues or clients. Column 2, line 1: What will it cost me if I continue to maintain it? Column 2, line 2: Lack of opportunities to collaborate on international projects, limited career prospects and isolation in important discussions. Column 3, line 1: If I manage to eliminate it, what will the positive changes be in my life? Column 3, line 2: By taking courses and practising regularly, I'll gain confidence, contribute more actively to international projects and develop my career.

Leadership: develop your strengths for successful speeches

The actor's trick? A state of mind! So, like him, say to yourself: "Nothing is possible without me!

After all, everything starts from what you project onto the other person. To create the conditions for a real encounter, you need to take into account your own state of mind and combine it with the assets that will help you develop your relationship.

4 major assets for your leadership

1/ The look

Firstly, it's only your intention that changes it. In other words, if you think or verbalise your intention, your gaze will translate it in your own way.

Example: "I want to be welcoming and caring".

Secondly, the proximity of your gaze affects its power. So make sure you keep the right distance for the situation.

2/ The voice

90 % of people don't like their voice when they hear it! Why is that?

The main reason is that they don't recognise it. It's a question of resonators and vibrations (larynx, labial, nasal, etc.) perceived by the inner ear.

The other reason: the voice can betray emotions, state of mind and personal history. For example, a low, self-effacing voice is often the sign of a lack of self-confidence.

The voice, through the intonation, volume and rhythm of the sentences, nurtures and animates the conversation and the relationship.

3/ The smile

The smile is universal, regardless of age or culture. Spontaneous, it expresses empathy and benevolence. It makes it easier to "meet" people. Conversely, a "forced" smile is noticeable and conveys a feeling of unease.

4/ Body language

According to a study by Dr Albert Mehrabian, a psychologist at the University of California, the majority of the message retained by those who have listened to it does not concern the words spoken but rather the way in which they were said, expressed and shown. This non-verbal communication is based on body language as a whole: gestures, postures, body and facial expressions.

Improvisation for leadership and public speaking

It's not the role of a leader to improvise, but it's a real quality to know how to improvise.

Improvisation makes a lot of things possible:

  • letting go and welcoming the unexpected
  • to have the right to be someone else
  • play down failure
  • learning to listen and accept what the other person says
  • getting used to getting out of any situation
  • gain confidence in yourself and your ideas
  • train to DARE

Work on your eloquence!

Eloquence is "the art of speaking well". It means pleasing, moving and convincing through the power of the spoken word. The power of the spoken word is the power to sell and to sell yourself. Eloquence is what gets you out of any situation. It's what enables you to be right even when you're wrong!

A few keys to successful speaking:

PleasingUse a gentle, comforting tone.
Being movingLet yourself be natural and let your emotions flow.
Resting and warming upYour body and voice need to be rested, then warmed up with exercises to loosen up the muscles and warm up the resonators.
For example: massage your mouth, lips, cheeks and neck. On a deep breath, recite the vowels continuously to calmly warm up your vocal cords.
InsuranceShow that you're sure of what you're saying, with a steady gaze that doesn't waver. A steady voice too. In theatre, you can use a voice called "from below" (i.e. speaking in a low voice).
SpeechIt should be regular, neither too slow nor too fast. It helps with comprehension.
Being convincingYou need to know your subject. Don't be hesitant, don't seem to be searching for your ideas.
Checklist with 6 pinned notes. Note 1: Pleasing, a gentle, comforting tone. Note 2 : Move, let your emotions speak for themselves. Note 3 : Rest then warm up, warm up the body, facial muscles and resonators. Note 4: Confidence, a frank look, a confident voice. Note 5: Elocution, controlled delivery. Note 6: Convincing, rehearsing and knowing your subject.

Ultimately, everyone can develop their leadership skills and improve their public speaking. This can be done through training. But there is also a particularly beneficial activity for working on your strengths: theatre. Because theatre is all about watching and listening. Looking where you're going, looking at others and listening to them. It's also about being able to catch people's eyes and to move around a space with your gaze. Finally, it's about being able to communicate with an audience through the emotion conveyed by those eyes.
