Michael Rosen asks William Laven about how he has learnt to embrace language and life with a stammer. For the first 10 years of his life, William Laven went to speech therapy with a stammer that was so severe he could not form a full sentence. Fast forward to today, William is now a 23-year-old podcast founder, Tedx speaker, stammer advocate, awareness raiser and campaigner. He is devoted to improving expectations for those with speech impediments, to challenge the stigma surrounding stammers, and to encourage children with stammers to believe in themselves. When it comes to his own stammer, he now believes it’s his superpower! Produced for BBC Audio Bristol by Becky Ripley
