Melbourne's Fluent, a brain-computer interface startup, has raised $2 million to revolutionize communication for speech-impaired individuals. This cutting-edge technology, developed at the University of Melbourne, offers a non-invasive solution to a long-standing challenge in the field of neurotechnology.
What makes Fluent's approach unique is its focus on capturing the intricate electrical signals in the brain that correspond to speech. Dr. Tim Mahoney, a biomedical engineer and co-founder of Fluent, draws an apt analogy: 'If you think of electrical signals as QR codes: when a person speaks, every individual mouth and jaw movement produces different 'QR codes' in their motor cortex.' This innovative perspective allows the device to interpret these 'QR codes' and convert them into speech, bypassing the need for invasive skull surgery.
The device, inserted under the scalp, operates by capturing brain activity in the motor cortex, the region responsible for speech muscles. Machine learning algorithms then translate this activity into text or audio, enabling individuals with neurological disorders like motor neurone disease and multiple sclerosis to communicate through their thoughts.
One of the standout features of Fluent's technology is its low-risk nature. Dr. Mahoney's research during his PhD demonstrated that the quality of electrical signals captured is comparable whether placed beneath or outside the scalp, eliminating the need for complex surgeries involving electrodes implanted inside the skull. This breakthrough has been validated through preliminary human testing at St Vincent's Hospital Melbourne.
The potential impact of Fluent's technology is immense. By making brain-computer interfaces more accessible and less invasive, it opens up new possibilities for individuals with speech impairments. The collaboration with a Japanese team to build the largest English dataset of its kind further strengthens the technology's accuracy and potential for widespread adoption.
As Fluent moves forward with clinical studies planned for later this year, the startup's journey from a University of Melbourne spinout to a $2 million-funded venture is a testament to the power of innovation. The support from the university's Genesis Pre-Seed Fund, Pacific Channel, Galileo Ventures, and other investors underscores the belief in Fluent's potential to transform lives and redefine the boundaries of neurotechnology.
