So far my experience is limited to talking books and magazines. However, I am often given the job of the customer and store announcements over the Tannoy system, and my voice has been described as "very cool"
I have O nd A levels alon with Associated Board graded instrumental exams which are Gd 8 Violin and GD 6 Piano. I have sung in all the major choral woks including the scratch Messiah, and have gigged toured recorded and taught drums for over thirty years.
In all the jobs I have had, and amongst freinds and people who don't know me, my voice and vocal abilities have often been commented upon, and recently I have worked on the 'phones for both Peugeot and Debenhms, and am often being asked to talk to clients and customers because of the way I speak and my commitment to my customers.
