Speak with Confidence Checklist

5 tips to present with more confidence

Your voice is an integral part of who you are - how you communicate with the world, how you present yourself, how you say what you have to say - or don’t say something.

The tone of your voice can either convey confidence or insecurity, it can be “in tune” with how you feel or the complete opposite.

It can help you convince people that what you have to say is true or make them doubt your sincerity.

It can be a source of joy and energy or utter frustration, if you don’t know how to use it.

Your voice is also a part of your body and therefore influenced by emotional, intellectual and physiological factors.

That's where I come in.

Thank you very very much!! I'm now paying much more attention to the "voice etiquette" and methods you taught in day-to-day situations, plus it gave a good impulse to improve other areas of my life :) I am aware mastering public speaking is a long-term process for me, but this training is the first time I feel I made progress on this! :)” Lara, public policy manager.

“I had two important presentations last week and both of them went well thanks to your coaching sessions :). I am really happy about the progress I made. It was a pleasure working with you.” Bettina, public relations officer.

“Thank you Sonja for everything! I will remember for very long what you have taught me !!! :-)I did not realize the coaching would go further than voice coaching only, which in the end helped me to reach my goals by taking into account the bigger picture. I have also learned a lot about self-branding which I did not realize would be offered as well. “ Sylvie, competition lawyer.
