AI Solutions for Paralyzed Patient Communication

NEW Brain Implant Helps Voiceless ALS Patient Communicate A milestone in restoring the ability to communicate to people who have lost it, - more than three times as fast as the previous record, - beginning to approach natural conversation speed of ~160 words/min. Study Participant: 68 yo woman with amyotrophic lateral sclerosis (ALS) a degenerative disease that can eventually cause #paralysis. Study published in Nature: - Two #brain #implants with ~120 electrodes to monitor #neural activity. - Trained an algorithm to recognize her intended words over four months, then - Combined that with a #language model that predicts words based on the context. - Using 125,000-words vocabulary, - system decoded attempted speech at the rate of 62 words per min, - with a 24 percent word-error rate. - Accurate enough to generally get the gist of a sentence. These results show a feasible path forward for restoring rapid communication to people with paralysis who can no longer speak. Nature | August 23, 2023 ------------------------- Francis R.

More advancements in healthcare with AI. Engineers develop AI-assisted wearable electronic patch allowing patients who lack the use of vocal cords to communicate verbally. A new bioelectric system invented by UCLA bioengineers can translate larynx muscle movements into audible speech. The device uses machine learning to correlate muscle movements with words, achieving nearly 95% accuracy. Designed as a non-invasive, wearable technology, it offers an alternative to current voice disorder treatments. The research team aims to expand the device’s vocabulary and test it on individuals with speech disorders. This technology could significantly aid those with dysfunctional vocal cords or recovering from related surgeries. https://lnkd.in/en7dKANd

Dr. David Moses and his colleagues have pulled off a miracle with A.I.: allowing paralyzed patients to "speak" through a video avatar in real time — using brain waves alone. In today's episode, David details how ML makes this possible 🤯 David: • Is an adjunct professor at the University of California, San Francisco. • Is the project lead on the BRAVO (Brain-Computer Interface Restoration of Arm and Voice) clinical trial. • The success of this extraordinary BRAVO project led to an article in the prestigious journal Nature and YouTube video that already has over 3 million views. Today’s episode does touch on specific machine learning (ML) terminology at points, but otherwise should be fascinating to anyone who’d like to hear how A.I. is facilitating real-life miracles. In this episode, David details:  • The genesis of the BRAVO project. • The data and the ML models they’re using on the BRAVO project in order to predict text, speech sounds and facial expressions from the brain activity of paralyzed patients. • What’s next for this exceptional project including how long it might be before these brain-to-speech capabilities are available to anyone who needs them. The SuperDataScience Podcast is available on all major podcasting platforms and a video version is on YouTube.

Ann Johnson, who suffered a brain stem stroke at age 30, was left with locked-in syndrome, paralyzed and mostly not able to speak for nearly 20 years. Recently, she became the first patient to benefit from a revolutionary AI-driven brain implant that decodes her brain signals, converting them to speech and facial expressions through a computerized avatar. While Johnson formerly communicated at 14 words per minute using a device that read her slight head movements, this new implant allows her avatar to articulate almost 80 words per minute. Researchers from the University of California San Francisco and the University of California Berkeley developed this neurotechnology, though similar advancements from Austrian researchers faced controversies. Johnson's involvement in the study has provided her a renewed sense of purpose and connection to society. Source: University of California San Francisco

Incredible- With the help of AI, a paralyzed woman got her voice back A recent breakthrough in medical technology has allowed a paralyzed woman to regain her ability to speak using a brain implant and an AI-powered digital avatar. This implantable device, developed by researchers led by UCSF neurosurgeon Edward Chang, translates brain signals into modulated speech and facial expressions. Here are the key details about this remarkable achievement :- -Implantable Device: The brain implant is a small panel of electrodes that is implanted onto the patient's brain. It is powered by artificial intelligence and is capable of decoding the patient's thoughts into synthesized speech and facial expressions. -Translation of Brain Signals: The implant translates the patient's brain signals into modulated speech and facial expressions, allowing the patient to communicate through a digital avatar. This breakthrough technology enables the patient to express herself and communicate with others, even though she is paralyzed. Restoring Communication: This innovation has given the paralyzed woman her voice back after 18 years of being unable to speak due to a stroke. It offers hope to other paralyzed patients who have lost their ability to communicate verbally. -Impact of AI: The use of artificial intelligence in this brain implant technology has significantly advanced the field of assistive communication devices for paralyzed individuals. By harnessing the power of AI, this device can accurately decode and translate the patient's thoughts into speech and facial expressions. This groundbreaking achievement demonstrates the potential of AI-powered brain implants in restoring communication abilities for paralyzed individuals. It opens up new possibilities for improving the quality of life for those who have lost their ability to speak. #ai #artificialintelligence #futureofai #artificalintelligencenow #technology #innovation #aiusecases #ml #machinelearning #deeplearning
