Lizzie Waterworth is the voice of Horrid Henry (for which she was BAFTA nominated), but she is also a voice artist in many other shows and video games, and has been working in the industry for 20 years. Recently she branched out into books, by writing 'How to Talk so People Will Listen' which offers practical advice to help children find their voice and boost confidence when speaking in front of other people. I spoke to her about her career and about the voice industry in general.
