A recent study shows that analysis using the soundtrack from a video recording system intended for small children could help researchers to identify children with autism.
"This application makes it possible to monitor the progress of development in a way that completely objective," said Dr. D. Kimbrough Oller, a professor at the Universty of Memphis, as quoted from page Healthday.com.
In that study, Oller and his team in his breast pocket recorder embedding children's clothing. Audio devices to record all the activities the children are in the natural environment throughout the day.
Oller with her team analyzed nearly 1,500 recorded soundtrack of the total 232 children aged ten months to four years.
Then, the system automatically separates voice from the children and the environment around them. The sounds and utterances are classified and assessed using established guidelines on the development of the theory of vocals.
From there, the researchers will be found consistent differences between children and those who previously had been diagnosed with autism or those with language delay. They can also predict the development of the normal child's age.
So what's different between the groups - the group? "The biggest difference is the extent to which children seem to display properly preparing syllables," Oller said.
This research has been published in the online edition of the National Academy of Sciences on July 19 to 23 editions.
One expert called the new research is very promising. "We are at an early stage to see this discovery as a way to detect people with autism," said the chief science officer for Autism Speaks Geraldine Dawson.
"I think this is very promising, but it would be more important if it can continue to study and replicate these findings," he added.
Dawson also said that one plus the value of the audio device is that it can be used at home without going to the hospital. "Not all children on the autism spectrum experience language delays. Vast majority of children with autism have shown some delay in language or early vocalization," Uajr Dawson.
"This could potentially be used for a screening tool," he added.
Before using this application, Dawson said that an analysis of the use vocalizations as observational way.
According to him, the experts agreed that many children who go on to develop autism attitude that experienced delays in conducting initial vocalizations.
"After using this system, the results of the analysis will be more objective," said Dawson.
For the record, according to data from the U.S. Centers for Disease Control and Prevention about one in 110 children in the United States today have suffered from autism. The report notes that a variety of disorders includes the development of communication, social and behavioral.
