One part of the programme was talking about companies using voice to enhance part of their brand not only within their advertising but as a whole, using the same voice artist for their radio ads and for their internal staff memos. Therefor increasing and creating consistent brand values throughout every aspect the company.
I found this so interesting because as a graphic designer it is integral for me to realise what a brand is, (not just a logo!) and I had never thought about how important a voice might be to a brand. Although it seems so obviously important now, the programme highlighted that it is often the last thing to be considered by the advertising industry too.
There is also great skill needed to be a voice artists, not just being able to read off a script. (although I think that might play a big part in it!) Often they have to fit vast amounts of information into only a few seconds, condensing their voice but not the quality.
