Researchers from the NHMRC Centre of Research Excellence in Speech and Language are calling for 3,000 Australians aged seven and above with experience of stuttering (past or present) to volunteer for the nation's largest ever Genetics of Stuttering Study.
The study aims to pinpoint the genes that predispose individuals to stuttering, which could revolutionise future research into the causes, treatment and prevention of the disorder.
Winner of The Voice Australia 2013 who has lived with stuttering since childhood, Harrison Craig, now 23, Melbourne, is teaming with study researchers and those who stutter nation-wide today, to lend his voice to this worthy cause.
The Murdoch Children's Research Institute, Walter and Eliza Hall Institute of Medical Research, QIMR Berghofer Medical Research Institute, Griffith University and the University of Melbourne are coordinating the Australian arm of this international study which involves 10 investigators at eight sites in Australia, the UK and The Netherlands. Recruitment closes December 2019.
According to Professor Angela Morgan, Co-Chief Study Investigator, speech pathologist and NHMRC Practitioner Fellow, Murdoch Children's Research Institute, Melbourne, boys and girls aged seven and above, together with men and women nation-wide who have a history of stuttering, may volunteer for the study.
"We are urgently seeking volunteers for our ground-breaking -Genetics of Stuttering Study'. Participation in our study is free and easy. Volunteers simply complete a 10-minute online survey and record a short sample of their speech. Those who qualify will be invited to provide a saliva sample for DNA analysis, to enable researchers to unravel the genes that predispose people to stuttering. Study participants will be making a genuine contribution to solving this disorder."
Stuttering is a disability that affects normal verbal fluency, and verbal communication – particularly the rhythm or flow of speech.
Although the exact cause of stuttering is unknown, genetics has been found to play a role, and a number of genetic variants have been identified to date.
"Globally, one per cent of adults stutter, and nearly 70 per cent of people who stutter report a family history of the disorder," said Prof Morgan.
"Importantly, gender is one of the strongest predisposing factors for stuttering. Boys are two-to-five times more likely to stutter than girls, and they are also less likely to recover spontaneously."
Harrison's family first identified his stutter at around four years of age while listening to him speak, and watching him "get stuck" when expressing certain sounds or words. Harrison continued to combat the speech disorder throughout childhood, adolescence, and into adulthood, and still recalls the anxiety he experienced when speaking publicly, or in social situations. Post- diagnosis, Harrison underwent rigorous treatment to learn how to better control his stutter.
"My treatment to date, has been effective to a degree, but I'm not sure free speech will ever come naturally to me. The truth is, to simply speak in social situations can be very exhausting," Harrison said. It was through music that Harrison finally found his true "voice", especially winning The Voice Australia 2013.
"To win The Voice Australia was something so special. I was really overwhelmed with happiness when I won," said Harrison.
Harrison is lending his voice to the Australian Genetics of Stuttering Study "to make a genuine difference to the lives of Australians who, like me, live with stuttering.
"Very little is understood about why people stutter, but I have faith that Professor Morgan and her associate researchers can make strong progress towards unlocking the mysteries of the human brain, and in turn, stuttering," Harrison said.

Sophie, 26, Melbourne works as a geospatial cartographer, designing utility maps for power, rail and gas networks. In her spare time, she pursues photography, singing and playing the guitar. Yet Sophie's honed technical skills and self-confidence have been hard-won, for she has lived with a stutter for most of her life.
At three years of age, Sophie's kindergarten (pre-school) teacher first identified Sophie's 'challenge" with speech – a speech disorder that she would continue to battle throughout her schooling years, and into adulthood.
Sophie, who has a family history of stuttering, has completed a variety of smooth speech courses over the years, and worked with a plethora of speech therapists and speech pathologists to improve her spoken word. Nowadays, her speech has significantly improved, along with her confidence, ten-fold.
Question: Can you talk about your first memory of realising your stutter?
Sophie: I didn't really realise I had a stutter at the time my mother told me it developed, it was more of a slow realisation. I was about 4 or 5 at the time, but I don't think I fully realised it until I was about 9 years old. It frustrated me at times when I couldn't get the words out, and the times this happened became more frequent. It didn't affect me too much during kindergarten or primary school but I became very, very self-conscious about it during high school.
Question: How does your stutter affect you, on a daily basis?
Sophie: I am a lot better than I previously was and I don't take it as hard if I do stutter these days. I have good days and bad days with my speech. Sometimes I can use my technique very well, but sometimes in more stressful days it can be difficult. But I never let my speech hold me back from saying what I want to say.
Question: How have you worked on your speech disorder, over the years?
Sophie: I first started seeing speech pathologists on and off throughout kinder/primary school, but unfortunately it never stuck outside the clinic and it got progressively worse. One of my last speech pathologists let me know about the Smooth Speech Intensive Program held at La Trobe University's Communication Clinic, and my mother and I agreed to go on the waiting list.
I undertook the program at about 14 years old and it was a complete game-changer- we were forced to speak very slowly and learn all the smooth speech techniques designed to make us less likely to stutter, and by the end of it I was completely fluent! But still, I was young and immature and I found it difficult to maintain. One year out of high school, I found myself having a lot of trouble carrying on what they had taught me and my parents recommended that I attend a Speak Easy meeting, a support group for those with a stutter.
