One of the biggest issues faced by teachers all over the world is voice problems that are caused by straining. As we attempt to project our voices across large classrooms and excited students, we are putting our voices at risk on a daily basis.
While working in schools, I have met many experienced professionals who have had to have surgery to remove nodules on their throat that have developed after years of over-straining.
I, myself, experienced the first-hand effects of this during one day of parent consultations when my voice completely disappeared. I wasn’t sick and there were no warning signs, it was as though my voice box just gave up and stopped working.
And, as you can imagine, trying to conduct meetings with parents when you have no voice is a pretty challenging task!
Over the years, I have looked into and discovered some useful strategies to help to protect my voice, like sipping warm water and speaking in a lower pitch.
However, the most effective strategy I have discovered is voice amplifiers. These save you from ever needing to project your voice across large spaces and will help you to take the best care of your voice and end the many years of abuse from over-straining.
Below is a recommended list of 12 voice amplifiers to help you to consider the best option for you and your teaching situation. I have also ranked the options by price, quality, and design to help you in the decision-making process.
