I have a Bachelor's of Science degree in Earth Science and Geology, and a Masters in Information Systems. I am a musician that plays violin, guitar, and piano to varying degrees.
I learned about voice overs through suggestions by customers of mine through the call centers I have worked at and am still employed at now full time as a senior technical agent.
Currently, I use Audacity to record and create MP3 files. If this venture takes off I am willing to upgrade my program to a paid service.
I have great diction, and have been working in a call center environment for 6 plus years. So, I get plenty of practice speaking clearly, and with a pleasant tone. As a technical support person, I do live walk-throughs of the product, and occasionally record short videos for the topic that is discussed.
