Australian researchers are examining how the social networking service Twitter can help those who are unable to communicate by speech.

The research's initial findings, conducted at the University of Newcastle, suggested Twitter is an important tool for adults with speech disabilities from stroke, traumatic brain injury, cerebral palsy, autism and motor neurone disease.

Associate Professor Bronwyn Hemsley told local media on Monday that many who use assistive technologies can already make their communication short and succinct, and tend to flourish on Twitter.

"Often, people with little or no functional speech find that listeners try to finish their sentences for them or speak on their behalf," Hemsley said. "They're used to crafting short messages carefully."

"In many ways, Twitter might level the playing field, liberating users from stereotypes and enabling self-advocacy."
