Why Should I Change the Way I Speak?
If you are happy with the way you speak, don't change it. But if you are not, do something about it.
When you are dissatisfied with something in your appearance, you can alter it, to the extent that is possible. The same is true for your speech. The way you use your voice and the manner in which you deliver your words is based on anatomy, language history, and habit. Your speech is so much more malleable than you may think! You may look good, but it is when you open your mouth and start communicating- that's how people really "see" you. And to a large extent, the way in which you see yourself.
If you speak in a low volume, you may be projecting a lack of self-confidence. People get tired of asking you to repeat yourself, so often don't. That can lead to all types of problems, both socially and professionally.
Speaking too fast can make you seem unsteady and affect credibility and overall presence. Monotones bore people. Trailing off frustrates people. Mumbling also hurts your image as a strong, confident, credible speaker.
Using upspeak or glottal fry make you sound adolescent, and do nothing for your image as a professional. Voices that sound "stuck in the throat" do not lend the kind of expression necessary to close the deal.
If you have an accent that makes it difficult for people to understand you at times, or robs you of your confidence, why not challenge yourself to change
All of these communication issues can be modified. Habits are hard to change by yourself; especially ones that are so deeply connected to your identity. Working with a professional can help you change old habits into ones that will enhance your presence, credibility and influence.
An afternoon tweak of a fancy facial might make you feel and look good for a while, but changing the way you speak and liking the way you sound will have much deeper and longer-lasting results.
