I am literally the "voice of my company". I do the voice overs for the podcasts, training videos, and phone systems for the company where I am currently employed. Frequently, our clients have told me that I should do voice overs professionally, so here I am.
I do not have any professional voice training other than the obligatory speech class in college. However, I love the theatre and was very active on stage at a very young age. I was able to translate that love to public speaking, corporate training, live demonstrations, online demonstrations, and video training.

I am a professional corporate trainer. It is my job to educate our clients on our products. The majority of the training that I do is online via webinars. Therefore, it is critical that verbal communication skills are excellent. My voice is the only method I have of communicating instrutional material to our clients. I have to make sure that I am clear and concise, yet interesting to listen to. In addition to the live webinars, I do the voice overs for our educational videos. The subject matter is very dry, so it is important that I use the proper tone and inflections to keep them interested.
