It’s funny that I spend so much energy to be careful to mask my natural Philadelphia accent, which just seems to flow from within. Just imagine the horror if I had recorded the commercial for Culligan Water as Culligan Wooder as I grew up saying. But regional dialect aside, I do accents in my work quite regularly.
I have family in London so I find doing a generic British accent comes quite easily. I am one of the voices on the UK Tampax channel, https://www.lauraschreibervoice.com/commercial/, and just get my nephews in my head and out it comes, which sounds really funny when talking about Tampons. I can differentiate between central London and South London, but the way my family sounds is my go to British accent.
I have also worked in a hispanic accent. I had to do a spot for Pandora radio as a Latina girl speaking English. Although Pandora has quite an accomplished bi-lingual roster, they needed someone who sounded solidly 13, and that was me. So, I went with somewhere in between Sophia Vergara and Selma Hayek and I gave them a few versions. As the producer himself was Latino I was so nervous to be accurate and not make it charactery. I gave them my standard three takes and it worked!
I have also worked in an array of regional American accents, from generic Southern to New York. What do I enjoy the most? When my family listens to the spot and is waiting for me to come and then they figure out they have been listening to me all along! Sometimes they say that my voice sounds deeper or that they were confused. I love it. I love that just a subtle change can throw even the people who know me best.
