AI Application Restores Voices for ALS Patients
New software helps individuals with speech impairments communicate using synthetic voice technology.
1Restoring Personal Voice
Anne-Marie Poirier, diagnosed with ALS in 2025, regained the ability to speak through a new AI tool called Vocality. The application simulates her original voice, allowing her to interact naturally with family members. This technology provides a vital emotional connection for patients suffering from progressive neurological diseases that destroy voluntary movement.
2Engineering a Solution
Founders Thomas Houlachi and David Ruiz developed Vocality after witnessing family members struggle with ALS. Houlachi, a biomedical engineering student, sought to reduce the frustration of letter-by-letter typing. The duo spent over two years testing the software with patients to ensure it addressed the specific communication barriers faced by those with impairments.
3Intuitive Communication Mechanism
Vocality allows users to enter only a few keywords, which the AI then expands into complete, coherent sentences. The tool can also listen to ongoing conversations and suggest relevant responses in real-time. By utilizing ElevenLabs technology, the app creates a synthetic voice that closely mimics the user's actual speech patterns and tone.
4Accessibility and Integration
The application is compatible with eye-tracking equipment, enabling individuals with limited mobility to select phrases using only their eyes. It currently supports six languages, including Italian, which allows users to communicate across different linguistic barriers. The software runs partially on-device to enhance privacy by reducing the need to send personal data externally.
5Development and Funding
The startup received $16,000 in support from Propolys, an incubator at Polytechnique Montréal, alongside $150,000 from fundraising and competition prizes. This financial backing supported the development of the iOS and iPad versions launched in June. An Android version is scheduled for release next week, expanding access to a broader user base across North America.
6Patient-Centric Design Process
Unlike many tech startups that prioritize features over user needs, Vocality founders integrated patient feedback throughout the development cycle. Users like Poirier regularly provided input, leading to features such as phrase libraries and repetition functions. This collaborative approach ensures the software remains intuitive and practical for those with rapidly changing physical abilities.
7Broader Clinical Application
While initially designed for ALS patients, Vocality is now utilized by individuals with other conditions, including cerebral palsy and aphasia. The tool serves over 100 daily users across North America. By focusing on authentic expression rather than just text generation, the platform helps maintain the fundamental human experience of speech for those affected.
8Ethical AI Implementation
Houlachi acknowledges public concerns regarding AI in healthcare but emphasizes that Vocality is designed to empower human expression. The firm collaborates with experts to ensure ethical deployment and safety. As the technology evolves, it continues to provide patients with a sense of agency and connection during the progression of incurable neurological illnesses.
