I have sang for different choirs for 12 years now (I currently sing as a deep bass for the University of Mary Washington), I also sing for a celtic band and have to present and describe things about the band and the instruments to the audience. I worked for a radio for 3 years in Chile while in College doing commercials, announcing and had my own little show as well. I also worked as a bilingual tour guide in the Chilean Patagonia for more than 10 years handling big groups of people and talking for hours every day.
Same as before, I have sang for different choirs for 12 years now and received training for that for many years, I also sing for a celtic band and have to present and describe things to the audience. I worked for a radio for 2 years in Chile while in College doing commercials, announcing and had my own little show as well; I went to several classes to improve in those areas.
I have skills with people as I'm used to deal with big groups (when I was a tour guide) so I have experience playing with my voice to make them more interested in what I'm telling them. I also have 2 master dregrees in both Physical and Chemical Oeanography so documentaries work perfectly for me as well. As a singer for a celtic band, I have to imitate celtic accents and also be funny.
